Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Company and Nature of Business | Note 1. The Company and Nature of Business Description of Business Sight Sciences, Inc. (the “Company”) was incorporated in the State of Delaware in 2010. The Company is located and headquartered in Menlo Park, California and has principal commercial offices in Southlake, Texas. The Company is an ophthalmic medical device company focused on the development and commercialization of surgical and nonsurgical technologies for the treatment of prevalent eye diseases. The Company’s Surgical Glaucoma segment's product portfolio features the OMNI® Surgical System, a device that facilitates the performance of both canaloplasty and trabeculotomy with a single device and single corneal incision to reduce intraocular pressure in adult patients with primary open-angle glaucoma. The Company’s Dry Eye segment's product portfolio consists of the TearCare® System ("TearCare") for ophthalmologists and optometrists. TearCare is a wearable eyelid technology that delivers highly targeted and adjustable heat to the meibomian glands of the eyelids in adult patients with evaporative dry eye disease due to meibomian gland disfunction. Initial Public Offering In July 2021, the Company completed an initial public offering (“IPO”) of its common stock in which the Company issued and sold 10,000,000 shares of its common stock, and sold an additional 1,500,000 shares of common stock upon the full exercise of the underwriters’ option to purchase additional shares of the Company's common stock. These sales occurred at the initial public offering price of $ 24.00 per share. The Company received net proceeds of approximately $ 252.2 million from the IPO, after deducting underwriting discounts and commissions of $ 19.3 million and offering costs of $ 4.5 million, of which $ 0.4 million were incurred as of December 31, 2020. Immediately prior to the closing of the IPO, all then-outstanding shares of redeemable convertible preferred stock were converted into 25,534,404 shares of common stock. Further, all outstanding redeemable convertible preferred stock warrants were converted into warrants to purchase 659,028 shares of common stock, which resulted in the reclassification of the convertible preferred stock warrant liability to additional paid-in capital. In connection with the Company’s IPO, the Company’s certificate of incorporation was amended and restated to provide for 200,000,000 authorized shares of common stock with a par value of $ 0.001 per share and 10,000,000 authorized shares of preferred stock with a par value of $ 0.001 per share. Stock Split In July 2021, the Company effected a 2-for-1 stock split of its issued and outstanding shares of common stock and a proportional adjustment to the existing conversion ratios for each series of the Company’s redeemable convertible preferred stock. Accordingly, all share and per share amounts for all periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the redeemable convertible preferred stock conversion ratios. Significant Risks and Uncertainties Since inception, the Company has incurred losses and negative cash flows from operations. As of December 31, 2021, the Company had an accumulated deficit of $ 153.0 million and recorded a net loss of $ 63.0 million for the year then ended and expects to incur future additional losses. If the Company’s revenue levels from its products are not sufficient or if the Company is unable to secure additional funding when desired, the Company may need to delay the development of its products and scale back its business and operations. The Company believes that its existing sources of liquidity will satisfy its working capital and capital requirements for at least 12 months from the issuance of its financial statements. Failure to generate sufficient revenues, achieve planned gross margins, or control operating costs will require the Company to raise additional capital through equity or debt financing. Such additional financing may not be available on acceptable terms, or at all, and could require the Company to modify, delay, or abandon some of its planned future expansion or expenditures or reduce some of its ongoing operating costs, which could harm its business, operating results, financial condition, and ability to achieve its intended business objectives. The ongoing COVID-19 pandemic has impacted, and is expected to continue to impact, demand for the Company's products, which are used in procedures and therapies that are considered elective. COVID-19 may also, directly or indirectly, have an unfavorable impact on other areas of the Company's business including, but not limited to, supply chain, sales, third party manufacturing, research and development costs and clinical studies. The full effect of the COVID-19 pandemic on the Company's financial condition and results of operations remain highly uncertain and cannot be predicted with confidence, and will depend on certain developments, including the duration and severity of the COVID-19 pandemic and its potential variants. The impact on the Company's customers and suppliers and the range of governmental and community reactions to the pandemic are uncertain. The Company may continue to experience reduced customer demand or constrained supply that could materially adversely impact business, financial condition, results of operations, liquidity and cash flows in future periods. |

Accounting Policies [Abstract] | |
Significant Accounting Policies | Note 2. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP). The Company’s consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sight Sciences UK, Ltd. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expense during the reporting period. The most significant estimates related to inventory excess and obsolescence, the selection of useful lives of property and equipment, determination of the fair value of stock option grants, the fair value of the redeemable convertible preferred stock warrants, and provisions for income taxes and contingencies. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and makes adjustments when facts and circumstances dictate. These estimates are based on information available as of the date of the financial statements. Actual results could differ from these estimates and such differences could be material to the Company’s financial position and results of operations. Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, redeemable convertible preferred stock, short-term and long-term debt and redeemable convertible preferred stock warrant liability. The Company states accounts receivable, accounts payable, and accrued and other current liabilities at their carrying value, which approximates fair value due to the short time to the expected receipt or payment. The carrying amount of the Company’s short-term debt approximates its fair value as the effective interest rate approximates market rates currently available to the Company. The redeemable convertible preferred stock warrant liability associated with the Company’s redeemable convertible preferred stock was carried at fair value based on unobservable market inputs. The carrying value of the warrants continued to be adjusted until the completion of the IPO, which occurred in July 2021. At that time, the preferred stock warrant liability was adjusted to fair value and reclassified to additional paid-in capital. Concentration of Credit Risk Financial instruments that subject the Company to concentration of credit risk consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are deposited with a high-quality financial institution. Deposits at this institution may, at times, exceed federally insured limits. Management believes that this financial institution is financially sound and, accordingly, that minimal credit risk exists. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company relies on third-party contract manufacturers for the manufacture of all of our commercial products currently available for sale. Disruption in production would have a negative impact on the Company’s financial position, results of operations and cash flows. For the years ended December 31, 2021 and 2020, there were no customers that represented 10 % or more of the Company's revenue. Deferred Offering Costs Deferred offering costs, consisting of legal, accounting and other fees and costs relating to the Company’s IPO, were deferred until completion of the IPO. As of December 31, 2020, deferred offering costs of $ 0.4 million were capitalized and are included in “Other noncurrent assets”. In July 2021, upon closing of the IPO, total deferred costs of $ 4.5 million were offset against the Company's IPO proceeds in additional paid in capital. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash and cash equivalents. Cash and cash equivalents are recorded at cost, which approximate fair value. As of December 31, 2021 and 2020, cash consists primarily of checking and savings deposits. The Company’s cash balances exceed those that are federally insured. To date, the Company has not recognized any losses caused by uninsured balances. Accounts Receivable and Provision for Doubtful Accounts Accounts receivable are stated at invoiced amounts, net of estimated provisions for doubtful accounts. The majority of customers are not extended credit and, therefore, time to maturity for receivables is short. The Company makes estimates of the collectability of customer accounts and provisions based primarily on analysis of historical trends and experience and changes in customers’ financial condition. The Company uses its judgment, based on the best available facts and circumstances, and records a provision against amounts due to reduce the receivable to the amount that is expected to be collected. These specific provisions are reevaluated and adjusted as additional information is received that impacts the amount reserved. To date, the Company has not experienced material credit-related losses. The provision for doubtful accounts was $ 0.6 million and $ 0.3 million as of December 31, 2021 and 2020, respectively. Inventory Inventory represents finished goods purchased from a third-party manufacturer and is valued at the lower of cost or net realizable value. Cost is determined using actual costs on a first-in, first-out basis for all inventory. Net realizable value is determined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company regularly reviews inventory quantities in consideration of actual loss experiences, projected future demand, and remaining shelf life to record a provision for excess and obsolete inventory when appropriate. The Company’s policy is to write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected lower of cost or net realizable value, and inventory in excess of expected requirements. The estimate of excess quantities is judgmental and primarily dependent on the Company’s estimates of future demand for the particular product. Property and Equipment, net Property and equipment are recorded at cost, less accumulated depreciation. Repairs and maintenance costs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, typically two to five years . When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. Construction-in-process assets consist primarily of tools and equipment that have not yet been placed in service. These assets are stated at cost and are not depreciated. Once the assets are placed into service, assets are reclassified to the appropriate asset class based on their nature and depreciated in accordance with the useful lives above. Impairment of Long-Lived Assets The Company assesses long-lived assets, including property and equipment, whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. If indicators of impairment exist, an impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition are less than their carrying amount. Impairment, if any, is measured as the amount by which the carrying amount of the long-lived assets exceeds their fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. The Company did no t record any impairment of long-lived assets for the years ended December 31, 2021 and 2020. Leases Contractual arrangements that meet the definition of a lease are classified as operating or finance leases and are recorded on the balance sheets as both a right-of-use asset (“ROU asset”) and lease liability, calculated by discounting fixed lease payments over the lease term at the Company’s incremental borrowing rate (“IBR”). Lease ROU assets and lease obligations are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company currently does not have any finance leases. Operating lease ROU assets are adjusted for (i) payments made at or before the commencement date, (ii) initial direct costs incurred, and (iii) tenant incentives under the lease. As the implicit rates for the operating leases are not determinable, the Company uses an IBR based on the information available at the respective lease commencement dates to determine the present value of future payments. IBR represents the interest rate that the Company would expect to incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis with similar terms and payments, in an economic environment where the leased asset is located. The Company considers a lease term to be the noncancelable period that it has the right to use the underlying asset, including any periods where it is reasonably certain the Company will exercise any option to extend the contract. Lease costs for minimum lease payments for operating leases are recognized on a straight-line basis over the lease term. Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. Variable lease payments that do not depend on an index or rate are recognized as lease costs when incurred. In measuring the ROU assets and lease liabilities, the Company has elected to combine lease and non-lease components. The Company does not recognize ROU assets or lease liabilities for short-term leases, if any, having initial terms of 12 months or less at lease commencement as an accounting policy election, and recognizes rent expense on a straight-line basis over the lease term for these types of leases. Redeemable Convertible Preferred Stock Warrants The Company’s redeemable convertible preferred stock warrants were classified as liabilities as the underlying redeemable convertible preferred stock was considered contingently redeemable and the Company was obligated to transfer assets to the holders upon occurrence of a deemed liquidation event. The warrants were recorded at fair value upon issuance and subject to remeasurement to fair value at each balance sheet date, with changes in fair value recognized as other expense in the statements of operations. The warrants liability was recorded as other noncurrent liabilities in the balance sheets. The Company continued to adjust the warrant liability for changes in fair value until the conversion of redeemable convertible preferred stock into common stock. At the time of conversion, the liability associated with the redeemable convertible preferred stock warrants was converted into warrants to purchase common stock and reclassified to additional paid-in capital. As a result of the conversion in the current year, the redeemable convertible preferred stock warrant liability was settled and will no longer be subject to remeasurement. Redeemable Convertible Preferred Stock The Company recorded its redeemable convertible preferred stock at fair value on the dates of issuance, net of issuance costs. A redemption event will be deemed to have occurred upon the liquidation or winding-up of the Company, a greater than 50% change in control, or sale of substantially all of the assets of the Company. In the event of a change of control of the Company, proceeds received from the sale of such shares will be distributed in accordance with the liquidation preferences set forth in the Company’s amended and restated certificate of incorporation, unless the holders of redeemable convertible preferred stock otherwise agree or have converted their shares into shares of common stock. Therefore, redeemable convertible preferred stock was classified outside of stockholders’ equity in the balance sheets, as events triggering the liquidation preferences are not solely within the Company’s control. During the current year, the holders of the redeemable convertible preferred stock agreed to have their shares converted into shares of common stock. At the time of conversion, the balances were reclassified to common stock and additional paid-in capital. Common Stock Warrant The Company’s common stock warrant is classified in equity as it meets all criteria for equity classification. The fair value of the common stock warrant was calculated using the BackSolve Method and is recorded at fair value upon issuance in additional paid-in capital in the consolidated balance sheets. The common stock warrant is not remeasured after the issuance date. Revenue Recognition The Company applies the following five steps in order to determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its arrangements: • Identify the contract with a customer, • Identify the performance obligations in the contract, • Determine the transaction price, • Allocate the transaction price to performance obligations in the contract, and • Recognize revenue as the performance obligations are satisfied. Revenue recognized during the years ended December 31, 2021 and 2020 relates entirely to the sale of the Company’s products within the Surgical Glaucoma and Dry Eye segments. These sales are primarily to hospitals, medical centers, and ECPs throughout the United States through sales representatives and distributors. The Company’s revenue arrangements consist of a single performance obligation. Revenue is recognized at the point in time when control of the promised goods transfer to the Company’s customers. Revenue is measured at the amount of consideration expected to be received in exchange for the transfer of goods. The amount of revenue that is recognized is based on the transaction price, which represented the invoiced amounts and includes estimates of variable consideration, such as discounted, where applicable. The Company does not offer right of return, except in the case where items are defective as manufactured, and the company does not typically provide customers with a right to a refund. The amount of variable consideration included in the transaction price may be constrained and is included only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Payment terms, typically 30 days, are offered to customers and do not include a significant financing component. The Company extends credit to customers based upon their financial condition and credit history and generally require no collateral. The Company does not have any contract balances related to product sales. Shipping and handling costs incurred for the delivery of goods to customers are included in cost of goods sold. In cases where the Company bills shipping and handling cost to customers, the Company classifies those amounts in net revenue. As a practical expedient, the Company recognizes the incremental costs of obtaining contracts, such as sales commissions, as an expense when incurred since the amortization period of the asset we otherwise would have recognized is one year or less. Sales commissions are recorded within selling, general, and administrative expenses in the statements of operations. Cost of Goods Sold The Company purchases its products from third-party manufacturers. Cost of goods sold consists primarily of costs related to materials, manufacturing overhead costs, reserves for excess, and obsolete and non-sellable inventories. Cost of goods sold also includes depreciation expense for production equipment and certain direct costs, such as shipping and handling costs. Research and Development The Company expenses research and development costs as incurred. Research and development expenses consist primarily of product development, clinical studies to develop and support the Company’s products, regulatory expenses, medical affairs, and other costs associated with products and technologies that are in development. Research and development expenses include employee compensation, including stock-based compensation, supplies, consulting, prototyping, testing, materials, travel expenses, depreciation, and an allocation of facility overhead expenses. Selling, General and Administrative Selling, general and administrative expenses include compensation, employee benefits, and stock-based compensation for executive management, finance administration, and human resources; facility costs (including rent); bad debt costs; professional service fees; and other general overhead costs, including depreciation to support the Company’s operations. Advertising Expense The Company expenses advertising costs as incurred. Advertising expenses for fiscal years 2021 and 2020 were $ 2.1 million and $ 0.8 million, respectively, included in selling, general, and administrative expenses in the statements of operations and comprehensive loss. Accounting for Payroll Protection Program In March 2020, Congress established the Paycheck Protection Program (“PPP”) to provide relief to small businesses during COVID-19 as part of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The legislation authorized the U.S. Treasury to use the Small Business Association’s (“SBA’s”) small business lending program to fund forgivable loans that qualifying businesses could spend to cover payroll, mortgage interest, rent, and utilities during the “Covered Period” defined as the 8-week period starting on the date the PPP loan proceeds are received. Upon meeting certain criteria as specified in the PPP program, the loans are eligible for partial or total forgiveness. In May 2020, the Company applied for and received a PPP loan for the amount $ 2.2 million from SBA. The PPP loan was fully forgiven in June 2021. U.S. GAAP does not contain authoritative accounting standards for forgivable loans provided by governmental entities to a for-profit entity. Absent authoritative accounting standards, interpretative guidance issued and commonly applied by financial statement preparers allows for the selection of accounting policies amongst acceptable alternatives. The Company determined it most appropriate to account for the PPP loan proceeds as an in-substance government grant by analogy to International Accounting Standards 20 (“IAS 20”) Accounting for Government Grants and Disclosure of Government Assistance . Under this guidance, a forgivable loan from government is treated as a government grant when there is reasonable assurance that the entity will meet the terms for forgiveness of the loan. While IAS 20 does not define “reasonable assurance”, this concept in practice is analogous to “probable” as defined in Financial Accounting Standards Board (“FASB”) ASC 450-20-20 under U.S. GAAP, which is the definition the Company has applied to its expectations of PPP loan forgiveness. Under IAS 20, government grants are recognized in earnings on a systematic basis over the periods in which the Company recognizes costs for which the grant is intended to compensate (i.e. qualified expenses). Further, IAS 20 permits for the recognition in earnings either separately under a general heading such as other income, or as a reduction of the related expenses. The Company has elected to recognize this government grant income as a reduction of the related expenses, and recognized $ 0.1 million, $ 0.3 million and $ 1.8 million as a reduction of cost of revenue, research and development and selling, general and administrative expenses, respectively for the year ended December 31, 2020. Stock-Based Compensation The Company measures and records the expense related to stock-based payment awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and uses the straight- line method to recognize stock-based compensation, and accounts for forfeitures as they occur. The Company selected the Black-Scholes-Merton (“Black-Scholes”) option-pricing model as the method for determining the estimated fair value for stock options. The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions, which determine the fair value of share-based awards, including the option’s expected term, expected volatility of the underlying stock, risk-free interest rate and expected dividend yield. Currency Remeasurement Foreign currency transaction gains and losses are recorded in other expense, net in the Company’s statements of operations and such amounts have not been material for all periods presented. Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Management makes an assessment of the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all off a deferred tax asset will not be realized. Due to the Company's historical operating performance and the recorded cumulative net losses in prior fiscal periods, the net deferred tax assets have been fully offset by a valuation allowance. The Company recognizes uncertain income tax positions at the largest amount that is more likely than not to be sustained upon audit by relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Changes in recognition or measurement are reflected in the period in which judgment occurs. The Company's policy is to recognize interest and penalties related to the underpayment of income tax as a component of provision for income taxes. Comprehensive Loss Comprehensive loss represents all changes in stockholders’ deficit except those resulting from distributions to stockholders. There have been no items qualifying as other comprehensive income (loss) and, therefore, for all periods presented, there was no difference between comprehensive loss and the Company’s reported net loss. Net loss per share attributable to common stockholders Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company considers all series of its redeemable convertible preferred stock and restricted stock awards to be participating securities as the holders are entitled to receive dividends on a pari passu basis in the event that a dividend is paid on common stock. Under the two-class method, the net loss attributable to common stockholders is not allocated to the redeemable convertible preferred stock or restricted stock awards as the holders of the Company’s redeemable convertible preferred stock and restricted stock awards do not have a contractual obligation to share in losses. Basic and diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period without consideration of potentially dilutive securities. The Company’s potentially dilutive shares, which consist of outstanding common stock options, restricted stock awards, common stock warrants, redeemable convertible preferred stock and redeemable convertible preferred stock warrants were excluded in the computation of diluted net loss per share for the period as the result would be anti-dilutive. Emerging growth company and smaller reporting company The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as well as a "smaller reporting company, as defined by the Securities and Exchange Commission per Rule 12b-2 of the Exchange Act. As such the Company is eligible for exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including reduced reporting and extended transition periods to comply with new or revised accounting standards for public business entities. The Company has elected to avail themselves of this exemption and, therefore, will not be subject to the timeline for adopting new or revised accounting standards for public business entities that are not emerging growth companies, and will follow the transition guidance applicable to private companies. Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. The guidance is effective for the Company beginning in the first quarter of 2023. The Company is evaluating the impact of adopting this guidance and does not expect to have a material impact on the Company’s financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , that simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intra-period tax allocation and modified the methodology for calculating income taxes in an interim period. It also clarifies and simplifies other aspects of the accounting for income taxes. The guidance is effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022 with early adoption permitted. The Company is evaluating the effect of this new guidance and does not expect it to have material impact on the Company’s financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. The amendment is effective for all entities through December 31, 2022. LIBOR is used to calculate the interest on borrowings under the Company’s term loan and revolving line of credit with MidCap Financial Services. The Company is evaluating the effect of this new guidance and does not expect it to have material impact on the Company’s financial statements. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | Note 3. Fair Value Measurements The Company reports all financial assets and liabilities and nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to measurements involving significant unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows: Level 1—Inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2—Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the related assets or liabilities. Level 3—Inputs are unobservable inputs for the asset or liability. The level in the fair value hierarchy within which a fair value measurement in its entirety is based on the lowest-level input that is significant to the fair value measurement in its entirety. The financial statements as of December 31, 2021 and 2020, do not include any nonrecurring fair value measurements relating to assets or liabilities. As of December 31, 2021, there were no liabilities that are measured at fair value on a recurring basis. The following table sets forth the fair value measurements of financial liabilities as of December 31, 2020 (in thousands): As of December 31, 2020 Level 1 Level 2 Level 3 Total Liabilities: Redeemable convertible preferred stock warrants liabilities $ — $ — $ 2,112 $ 2,112 Total liabilities measured at fair value $ — $ — $ 2,112 $ 2,112 The Company measures the redeemable convertible preferred stock warrants using Level 3 unobservable inputs within the Black-Scholes option-pricing model. The key assumptions include the fair value of redeemable convertible preferred stock, volatility, the risk-free interest rate, expected term (remaining contractual term of the warrants) and dividend yield. The Company has limited historical volatility information available, and the expected volatility was based on actual volatility for comparable public companies projected over the expected terms of the warrants. The Company did not apply a forfeiture rate to the warrants as there is not enough historical information available to estimate such a rate. The risk-free interest rate was based on the U.S. Treasury yield curve at the time of the grant over the expected term of the warrants. Refer to Note 9 for the assumptions used. The Company measures the fair value of outstanding debt for disclosure purposes on a recurring basis. As of December 31, 2021 and 2020, total debt of $ 32.7 million and $ 32.0 million is reported at amortized cost, respectively. This outstanding debt is classified as Level 2 as it is not actively traded. The amortized cost of the outstanding debt approximates the fair value. The Company determines the fair value of the redeemable convertible preferred stock warrants quarterly, with subsequent gains and losses from remeasurement of Level 3 financial liabilities recorded through other expense, net in condensed statements of operations and comprehensive loss. A summary of the changes in the fair value of the Company’s Level 3 financial instruments for the years ended December 31, 2021 and 2020, is as follows (in thousands): Redeemable convertible preferred stock warrants liabilities Balance – December 31, 2019 $ 236 Issuance of redeemable convertible preferred stock warrants 1,812 Change in fair value 136 Expiration of redeemable convertible preferred stock warrants ( 72 ) Balance – December 31, 2020 2,112 Change in fair value 6,861 Conversion of preferred stock warrants to common stock warrants upon the closing of the IPO ( 8,973 ) Balance – December 31, 2021 $ — |

Debt Disclosure [Abstract] | |
Debt | Note 5. Debt In January 2019, the Company entered into credit and security agreements with MidCap Financial Services, or the Lender, which provided a maximum of $ 25.0 million credit facility consisting of a $ 20.0 million senior secured term loan (the "2019 Term Loan") and a $ 5.0 million 2019 revolving loan (the "2019 Revolver" and collectively with the 2019 Term Loan, the “2019 MidCap Credit Facility”). In November 2020, the Company entered into amended and restated credit and security agreements with the same institution, which replaced the 2019 MidCap Credit Facility, and provided for a maximum of $ 40.0 million credit facility consisting of a $ 35.0 million senior secured term loan (the "2020 Term Loan") and a $ 5.0 million revolving loan (the "2020 Revolver and collectively with the 2020 Term Loan, the “2020 MidCap Credit Facility”). The obligations under the MidCap Loan Agreements are guaranteed by the Company's current and future subsidiaries, subject to exceptions for certain foreign subsidiaries. Obligations under the agreements are secured by substantially all assets of the Company, including material intellectual property. Additionally, the Company is subject to customary affirmative and negative covenants as defined in the credit agreement, including covenants that limit or restrict the ability to, among other things, incur indebtedness, grant liens, merge or consolidate, make investments, dispose of assets, make acquisitions, pay dividends or make distributions, repurchase stock and enter into certain transactions with affiliates, in each case subject to certain exceptions. The agreements also have financial covenants that relate to minimum trailing revenue targets, which began in November 2020, and are tested on a monthly basis. As of December 31, 2021, the Company was in compliance with all financial and non-financial covenants. The MidCap Loan Agreements each contain events of default that include, among others, non-payment of principal, interest or fees, breach of covenants, inaccuracy of representations and warranties, cross-defaults and bankruptcy and insolvency events. 2020 Term Loan The 2020 Term Loan has a five-year term and has a stated floating interest rate which equates to reserve- adjusted LIBOR + 7.00 %. The effective interest rate at December 31, 2021 was 12.94 %. The 2020 Term Loan is split into three tranches as follows: (i) the Tranche One Loans provide for $ 12.0 million in term loans which are deemed to have been converted from Tranche One Loans that were drawn and outstanding under the 2019 Term Loan immediately prior to entering into 2020 MidCap Credit Facility, (ii) the Tranche Two Loans provided for up to $ 2.0 million in term loans which are deemed to have been converted from Tranche Two Loans that were drawn and outstanding under the 2019 Term Loan immediately prior to entering into 2020 MidCap Credit Facility, and (iii) the Tranche Three Loans provided for up to $ 21.0 million in new term loans. The Company borrowed $ 21.0 million under the Tranche Three Loans in November 2020. The 2020 Term Loan requires monthly interest-only payments , which began in December 2020. Principal payments are scheduled to begin in December 2022, however, the interest-only period can be extended by an additional 24 months provided that the Company is in compliance with certain financial covenants and other terms as defined in the MidCap Loan Agreements. The Company currently has the ability to and intends to extend the interest-only period through December 2023. In conjunction with entry into the 2020 MidCap Credit Facility, the Company issued a 10-year warrant to the Lender to purchase 300,000 shares of the Company’s Series F redeemable convertible preferred stock (the “2020 Warrant”) at an exercise price of $ 21.88 per share (see Note 9). The estimated fair value at issuance of the 2020 Warrant of $ 1.8 million. The 2020 Warrant was recorded at the fair value as a debt discount and as a warrant liability. In addition, the Company incurred $ 0.5 million of issuance costs paid to the Lender in conjunction with the 2020 Term Loan which represents a debt discount. The Company concluded that the 2020 Term Loan represented a modification of the 2019 Term Loan and accounted for the 2020 Term Loan as debt modification. A final payment fee of 6 % of the amounts borrowed is payable at the end of the term or when the borrowings are repaid in full. A long-term liability is being accreted using the effective interest method for the final payment fee over the term of the loan agreement. The borrowings are collateralized by a security interest in substantially all of the Company’s assets. The Company accrued $ 0.9 million and $ 0.5 million as of December 31, 2021 and 2020, respectively, related to accretion of final payment due at maturity per the agreement using the effective interest rate method. 2020 Revolver The 2020 Revolver has a four-year term and has a stated floating interest rate which equates to reserve- adjusted LIBOR plus 4.50 %. An unused line fee of 0.5 % is payable monthly based on the average unused balance and a collateral management fee of 0.5 % is payable monthly based on the outstanding balance of the 2020 Revolver. The Company can request to increase the 2020 Revolver commitment amount to $ 15.0 million under the term of the agreement. As of December 31, 2021, $ 5.0 million was available to be drawn under the 2020 Revolver. Long-term and short-term debt as of December 31, 2021 and 2020 was as follows (in thousands): As of December 31, 2021 2020 2020 Term Loan $ 35,000 $ 35,000 Total principal payments due 35,000 35,000 Less: debt discount related to warrant liability and issuance costs ( 2,344 ) ( 3,045 ) Total amounts outstanding 32,656 31,955 Less: Current portion — — Total accrued and other current liabilities $ 32,656 $ 31,955 The repayment schedule relating to the Company’s principal debt as of December 31, 2021, is as follows (in thousands): Amount 2022 — 2023 ( 1,458 ) 2024 ( 17,500 ) 2025 ( 16,042 ) Total repayments $ ( 35,000 ) |

Commitments and Contingencies | Note 6. Commitments and Contingencies Operating Lease Obligations The Company’s leases include facility leases and storage leases. In determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date if the rate implicit in the lease is not readily determinable. The Company estimates its incremental borrowing rate based on qualitative factors including company specific credit offers, lease term, general economics, and the interest rate environment. In September 2019, the Company entered into a noncancelable operating lease for approximately 10,823 square feet of primary office space, which expired on July 31, 2021 , without the option to extend. On February 5, 2021, the Company entered into a lease to renew the corporate headquarters in Menlo Park, California. The lease commenced on August 1, 2021 and is for a term of 37 months from the commencement date. The Company recorded an aggregate right-of-use ("ROU") asset and lease liability of $ 1.5 million. The ROU asset and corresponding lease liability were estimated using a weighted-average incremental borrowing rate of 13.59 %. Total base rent is approximately $ 1.6 million under the lease agreement. The Company recognizes rent expense on a straight-line basis over the noncancelable lease term. The Company’s rent expense was $ 0.7 million and $ 0.7 million for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021, the remaining lease term for the lease was 2.6 years. Operating lease expense and supplemental cash flow information related to operating leases for the years ended December 31, 2021 and 2020 were as follows (in thousands): Year Ended December 31, 2021 2020 Operating lease expense $ 702 $ 663 Cash paid for operating leases 657 694 New operating lease assets obtained in exchange for 1,537 — Aggregate future minimum lease payments at December 31, 2021 under these noncancelable operating leases was as follows (in thousands): As of December 31, 2021 2022 $ 693 2023 706 2024 462 Total future minimum lease payments $ 1,861 Less: imputed interest ( 311 ) Present value of future minimum lease payments $ 1,550 Less: current portion of operating lease liability ( 510 ) Operating lease liabilities - noncurrent $ 1,040 Indemnification In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and provide for general indemnifications. The Company’s exposure under these agreements is unknown because it involves claims that may be made against the Company in the future, but that have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification obligations. However, the Company may record charges in the future as a result of these indemnification obligations. The Company indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits, while the director is or was serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The term of the indemnification period lasts as long as a director may be subject to any proceeding arising out of acts or omissions of such director in such capacity. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds director liability insurance. This insurance allows the transfer of risk associated with the Company’s exposure and may enable it to recover a portion of any future amounts paid. The Company believes that the fair value of these indemnification obligations is minimal. Accordingly, the Company has not recognized any liabilities relating to these obligations as of December 31, 2021 and 2020. Contingencies From time to time, we may become involved in legal proceedings arising in the ordinary course of business. We are not currently a party to any material legal proceedings. |

Redeemable Convertible Preferred Stock Warrants 2019 Warrants Under the 2019 Term Loan, the Company issued the 2019 Warrants to purchase shares of its Series C redeemable convertible preferred stock. At initial recognition, the warrants were recorded at fair value and were subject to remeasurement at each balance sheet date. Subsequent to the IPO in 2021, the outstanding warrants were converted to common stock, which resulted in the re-classification of the convertible preferred stock warrant liability to additional paid-in-capital. As of December 31, 2020, the estimated fair value of the warrants was $ 0.3 million. The fair value was calculated using the Black-Scholes option-pricing model with the following assumptions: December 31, 2020 Expected term (in years) 8.1 – 8.5 Expected volatility 42.18 % – 42.63 % Risk-free interest rate 2.33 % – 2.49 % Dividend yield – 2020 Warrant In conjunction with entering into the 2020 Term Loan agreement, the Company issued the 2020 Warrant to purchase 300,000 shares of its Series F redeemable convertible preferred stock. The warrant was immediately exercisable at an exercise price per share of $ 21.88 and expires 10 years from its date of issuance. The estimated fair value of the warrant on the date of issuance was $ 1.8 million. As of the issuance date, the fair value was calculated using a Multi-scenario Method with Discounts for Lack of Marketability for each class of security. At initial recognition, the warrant was recorded at its estimated fair values and was subject to remeasurement at each balance sheet date. Upon the completion of the IPO, the outstanding warrant was converted to purchase 600,000 shares of common stock, which resulted in the re-classification of the convertible preferred stock warrant liability to additional paid-in capital. In August 2021, the warrant was net exercised and the Company issued 431,708 shares of common stock. At December 31, 2020, the estimated fair value of the 2020 Warrant was $ 1.8 million. The fair value of the redeemable convertible preferred stock warrants was determined using the following assumptions: December 31, 2020 Term (in years) 0.58 – 2.58 Expected volatility 55.9 % - 65.6 % Risk-free interest rate 0.08 % - 0.18 % |

Equity Incentive Plans | Note 11. Equity Incentive Plans 2011 Stock Option Plan and 2021 Equity Incentive Plan In 2011, the Company established its 2011 stock option plan (the “2011 Plan”) that provided for the granting of stock options to employees and nonemployees of the Company. In July 2021, the Company’s Board of Directors and stockholders adopted and approved the 2021 Equity Incentive Plan, (the “2021 Plan”). Under the 2021 Plan, the Company had the ability to issue incentive stock options ("ISOs"), nonqualified stock options ("NSOs"), stock appreciation rights, dividend equivalent rights, restricted stock awards, and restricted stock unit awards. Options under the 2021 Plan could be granted for periods of up to 10 years. For incentive stock options granted to a grantee who, at the time the option is granted, owns stock representing more than 10% of the voting power of all classes of stock of the Company or any parent or subsidiary of the Company, the term of the incentive stock option may be granted for periods of up to five years. The ISOs and NSOs will be granted at a price per share not less than the fair value at the date of grant. The exercise price of an ISO granted to a 10% stockholder shall not be less than 110% of the estimated fair value of the shares on the date of grant, as determined by the board of directors. Options granted to new hires generally vest over a four-year period, with 25% vesting at the end of one year and the remaining vesting monthly thereafter; options granted as merit awards generally vest monthly over a four-year period. The Company reserved 5,200,000 shares of common stock for future issuance under the 2021 Plan. The Company’s 2011 Stock Plan was terminated in connection with the IPO and no further grants will be made under the 2011 Plan from the date that the 2021 Plan became effective. The terms under the 2011 Plan are consistent with those described above for the 2021 Plan. The Company had the ability to issue ISOs, NSOs, stock appreciation rights, dividend equivalent rights, restricted stock awards, and restricted stock unit awards. At December 31, 2021 and 2020, there were 5,321,687 shares and 451,670 shares, respectively, of common stock available for issuance under the 2021 and 2011 Plans, respectively. Stock Option Awards The following table summarizes stock option activity under the 2011 and 2021 Plans: Number of Weighted-Average Exercise Price Weighted-Average Average Intrinsic Value Outstanding, December 31, 2020 3,137,776 $ 0.94 6.8 $ 18,656 Grants 2,487,253 11.35 Forfeited/cancelled ( 150,520 ) 3.77 Exercised ( 477,564 ) 0.78 Outstanding, December 31, 2021 4,996,945 $ 6.05 7.6 $ 58,420 Vested and exercisable as of December 31, 2021 2,098,249 $ 2.22 5.6 $ 32,268 Vested and expected to vest as of December 31, 2021 4,963,575 $ 6.09 7.6 $ 57,895 The weighted-average grant-date fair values of options granted during the year ended December 31, 2021 and 2020 was $ 11.35 and $ 2.90 per share, respectively. The aggregate intrinsic value of options exercised were $ 7.3 million during the year ended December 31 , 2021. The aggregate intrinsic value was calculated as the difference between the exercise prices of the underlying options and the estimated fair value of the common stock on the date of exercise. As of December 31, 2021, the unrecognized stock-based compensation of unvested opti ons was $ 23.3 million, which is expected to be recognized over a weighted-average period of 3.29 years. Determination of fair value The Company estimated the fair value of stock options using the Black-Scholes option-pricing model. The fair value of stock options is recognized on a straight-line basis over the requisite service periods of the awards. The fair value of stock options was estimated using the following weighted-average assumptions: Years ended December 31, 2021 2020 Expected term (in years) 4.99 – 6.18 5.85 - 6.08 Expected volatility 56.74 % – 61.08 % 48.27 %- 55.64 % Risk-free interest rate 0.47 % – 1.33 % 0.33 %- 1.77 % Dividend yield – – Expected Term The expected term is calculated using the simplified method, which is available if there is insufficient historical data about exercise patterns and post vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant or for each vesting tranche for awards with graded vesting. The midpoint of the vesting date and the maximum contractual expiration date is used as the expected term under this method. For awards with multiple vesting tranches, the time from grant until the midpoints for each of the tranches may be averaged to provide an overall expected term. Expected Volatility The Company used an average historical stock price volatility of a peer group of publicly traded companies to be representative of its expected future stock price volatility, as the Company did not have any trading history for its common stock. For purposes of identifying these peer companies, the Company considered the industry, stage of development, size, and financial leverage of potential comparable companies. For each grant, the Company measured historical volatility over a period equivalent to the expected term. Risk-Free Interest Rate The risk-free interest rate is based on the implied yield currently available on US Treasury zero-coupon issues with remaining terms equivalent to the expected term of a stock award. Expected Dividend Rate The Company has not paid, and does not anticipate paying, any dividends in the near future. Accordingly, the Company has estimated the dividend yield to be 0 %. Restricted Stock Units RSUs are share awards that entitle the holder to receive freely tradable shares of the Company’s common stock upon vesting. The RSUs cannot be transferred, and the awards are subject to forfeiture if the holder’s employment terminates prior to the release of the vesting restrictions. The RSUs generally vest over a four-year period with straight-line vesting in equal amounts on an annual basis, provided the employee remains continuously employed with the Company. The fair value of the RSUs is equal to the closing price of the Company’s common stock on the grant date. The following table summarizes restricted share award activity: Number of Weighted-Average Grant Date Fair Value Per Share Outstanding, December 31, 2020 — $ — Grants 53,250 22.91 Forfeited/cancelled — — Vested — — Outstanding, December 31, 2021 53,250 $ 22.91 There were no RSUs granted prior to 2021. During the year ended December 31, 2021, the Company recorded stock-based compensation of less than $ 0.1 million related to the RSUs. As of December 31, 2020, there was $ 1.2 million of total unrecognized compensation cost related to the RSUs that is expected to be recognized over a weighted-average period of 3.75 years. Stock Based Compensation The following is a summary of stock-based compensation expense by function (in thousands): Years Ended December 31, 2021 2020 Cost of goods sold $ 71 $ 20 Research and development 495 84 Selling, general and administrative 4,517 393 Total stock-based compensation expense $ 5,083 $ 497 2021 Employee Stock Purchase Plan In July 2021, the Board of Directors and stockholders also adopted and approved the 2021 Employee Stock Purchase Plan (the “ESPP”). The Company reserved 850,000 shares of common stock for future issuance under the ESPP. As of December 31, 2021, no shares of common stock have been purchased under the ESPP. |

Net Loss per Share Attributable to Common Stockholders | Note 12. Net Loss per Share Attributable to Common Stockholders Basic net loss per share is computed by dividing the net loss by the weighted-average number of common shares outstanding for the period. As the Company reported a net loss for the years ended December 31, 2021 and 2020, basic net loss per share is the same as diluted net loss per share as the inclusion of potentially dilutive shares would have been antidilutive if included in the calculation. The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders (in thousands, except share and per share data): Year Ended December 31, 2021 2020 Numerator: Net loss attributable to common stockholders $ ( 62,960 ) $ ( 34,693 ) Denominator: Weighted-average shares of common stock 26,734,097 9,356,218 Net loss per share attributable to common $ ( 2.36 ) $ ( 3.71 ) The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share attributable to common stockholders for the period presented because including them would have been antidilutive: December 31, 2021 2020 Redeemable convertible preferred stock — 12,767,202 Redeemable convertible preferred stock warrants — 329,514 Options to purchase common stock 4,996,945 3,137,776 Restricted stock units 53,250 — Total 5,050,195 16,234,492 |

The income tax effect of temporary differences that give rise to deferred tax assets and (liabilities) consist of the following (in thousands): December 31, 2021 2020 Deferred tax assets: Net operating loss carryforwards $ 35,186 $ 22,208 Deferred compensation 1,812 899 Research and development credits 1,497 1,071 Operating lease liability 405 138 Provision for bad debt 163 75 Provision for excess and obsolete inventories 28 282 Other 104 19 Gross deferred tax assets 39,195 24,692 Less: Valuation allowance ( 38,804 ) ( 24,543 ) Deferred tax assets, net of valuation allowance 391 149 Operating lease right-of-use assets ( 391 ) ( 135 ) Fixed Assets — ( 14 ) Deferred tax liabilities: ( 391 ) ( 149 ) Net deferred tax assets $ — $ — Internal Revenue Code (IRC) Section 382 limits the use of federal net operating losses and income tax credit carryforwards in certain situations where changes occur in stock ownership of a company. If the Company should have an ownership change of more than 50% of the value of the Company’s capital stock, utilization of the carryforwards could be restricted. The reconciliation of the statutory federal income tax rate to the Company’s effective tax rate is as follows (in thousands): December 31, 2021 2020 Tax at statutory federal rate 21 % 21 % State tax, net of federal benefit 5 % 5 % Research and development credit 1 % 1 % Change in valuation allowance ( 24 )% ( 27 )% Other ( 3 )% — Effective tax rate — — A valuation allowance is recorded when it is more likely than not that some portion of the deferred tax assets will not be realized. As of each reporting date, the Company’s management considers all evidence, both positive and negative, that could affect management’s view with regard to future realization of deferred tax assets. As of December 31, 2021 and 2020, a full valuation allowance for deferred tax assets was recorded as management believes it is more likely than not that all of the deferred tax assets will not be realized in the future. At December 31, 2021, and 2020, the Company has a net operating loss carryforward for federal income tax purposes of approximately $ 136.8 million and $ 85.3 million, respectively. At December 31, 2021 and 2020, the Company has a net operating loss carryforward for state income tax purposes of approximately $ 126.6 million and $ 83.5 million, respectively. Net operating losses prior to 2018 of $ 14.8 million will expire, if not utilized, beginning in 2032 for federal and state income tax purposes. As of December 31, 2021 and 2020, the Company has federal research and development income tax credit carryforwards of approximately $ 1.2 million and $ 0.8 million, respectively. As of December 31, 2021 and 2020, the Company has state research and development income tax credit carryforwards of approximately $ 0.9 million and $ 0.9 million, respectively. The Federal income tax credits begin to expire in 2032. The Company has a full valuation allowance on research and development tax credits as of December 31, 2021 and 2020. The state research and development credits can be carried forward indefinitely. The total amount of uncertain tax positions (UTP) on research and development tax credits is $ 0.6 million and $ 0.4 million as of December 31, 2021 and 2020, respectively. The Company does not expect any significant change to the UTP balances in the next 12 months . The following table summarizes the activity related to the unrecognized tax benefits (in thousands): December 31, 2021 2020 Unrecognized tax benefits at the beginning of the year $ 417 $ 304 Additions based on tax positions related to the current year 163 113 Additions for tax positions of prior years — — Unrecognized tax benefits at the end of the year $ 580 $ 417 The Company does not have any material uncertain tax positions as of December 31, 2021 and does not expect any significant change to such balances in the next twelve months.

Segment Reporting [Abstract] | |
Segment Information | Note 14. Segment Information The Company has two reportable operating segments which are determined on the basis of product portfolio: Surgical Glaucoma and Dry Eye. The operating and reportable segments were determined based on how the Company’s Chief Executive Officer, its Chief Operating Decision Maker (“CODM”), views and evaluates the Company’s operations. The CODM allocates resources to and evaluates the financial performance of each operating segment primarily based on gross profit and gross profit margin. Surgical Glaucoma segment includes sales of the Company’s OMNI® Surgical System for use in minimally invasive glaucoma procedures. Dry Eye segment includes sales of the Company’s TearCare® System and related components. The following table summarizes select operating results information for each reportable segment (dollars in thousands): Year Ended December 31, 2021 2020 Revenue Surgical Glaucoma $ 46,496 $ 26,000 Dry Eye 2,460 1,640 Total 48,956 27,640 Cost of goods sold Surgical Glaucoma 6,473 7,069 Dry Eye 2,137 2,140 Total 8,610 9,209 Gross profit Surgical Glaucoma 40,023 18,931 Dry Eye 323 ( 500 ) Total 40,346 18,431 Operating expense 91,824 50,619 Loss from operations ( 51,478 ) ( 32,188 ) Interest income — 30 Interest expense ( 4,366 ) ( 2,403 ) Other expense, net ( 6,928 ) ( 71 ) Loss before income tax $ ( 62,772 ) $ ( 34,632 ) The Company does not allocate any income and expenses beyond revenue and cost of goods sold to the reportable operating segments in its reporting to the CODM. No asset information is provided for reportable operating segments because they are not reviewed by the CODM on segment basis. Substantially all of the Company’s revenue is generated from sales in the United States. |

Summary of Significant Accoun_2
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |
Dec. 31, 2021 | |
Accounting Policies [Abstract] | |
Basis of Accounting | Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP). The Company’s consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Sight Sciences UK, Ltd. All intercompany balances and transactions have been eliminated in consolidation. |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expense during the reporting period. The most significant estimates related to inventory excess and obsolescence, the selection of useful lives of property and equipment, determination of the fair value of stock option grants, the fair value of the redeemable convertible preferred stock warrants, and provisions for income taxes and contingencies. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, and makes adjustments when facts and circumstances dictate. These estimates are based on information available as of the date of the financial statements. Actual results could differ from these estimates and such differences could be material to the Company’s financial position and results of operations. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, accrued liabilities, redeemable convertible preferred stock, short-term and long-term debt and redeemable convertible preferred stock warrant liability. The Company states accounts receivable, accounts payable, and accrued and other current liabilities at their carrying value, which approximates fair value due to the short time to the expected receipt or payment. The carrying amount of the Company’s short-term debt approximates its fair value as the effective interest rate approximates market rates currently available to the Company. The redeemable convertible preferred stock warrant liability associated with the Company’s redeemable convertible preferred stock was carried at fair value based on unobservable market inputs. The carrying value of the warrants continued to be adjusted until the completion of the IPO, which occurred in July 2021. At that time, the preferred stock warrant liability was adjusted to fair value and reclassified to additional paid-in capital. |
Concentration Of Credit Risk | Concentration of Credit Risk Financial instruments that subject the Company to concentration of credit risk consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are deposited with a high-quality financial institution. Deposits at this institution may, at times, exceed federally insured limits. Management believes that this financial institution is financially sound and, accordingly, that minimal credit risk exists. The Company has not experienced any losses on its deposits of cash and cash equivalents. The Company relies on third-party contract manufacturers for the manufacture of all of our commercial products currently available for sale. Disruption in production would have a negative impact on the Company’s financial position, results of operations and cash flows. For the years ended December 31, 2021 and 2020, there were no customers that represented 10 % or more of the Company's revenue. |
Deferred Offering Costs | Deferred Offering Costs Deferred offering costs, consisting of legal, accounting and other fees and costs relating to the Company’s IPO, were deferred until completion of the IPO. As of December 31, 2020, deferred offering costs of $ 0.4 million were capitalized and are included in “Other noncurrent assets”. In July 2021, upon closing of the IPO, total deferred costs of $ 4.5 million were offset against the Company's IPO proceeds in additional paid in capital. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash and cash equivalents. Cash and cash equivalents are recorded at cost, which approximate fair value. As of December 31, 2021 and 2020, cash consists primarily of checking and savings deposits. The Company’s cash balances exceed those that are federally insured. To date, the Company has not recognized any losses caused by uninsured balances. |
Accounts Receivable and Provision for Doubtful Accounts | Accounts Receivable and Provision for Doubtful Accounts Accounts receivable are stated at invoiced amounts, net of estimated provisions for doubtful accounts. The majority of customers are not extended credit and, therefore, time to maturity for receivables is short. The Company makes estimates of the collectability of customer accounts and provisions based primarily on analysis of historical trends and experience and changes in customers’ financial condition. The Company uses its judgment, based on the best available facts and circumstances, and records a provision against amounts due to reduce the receivable to the amount that is expected to be collected. These specific provisions are reevaluated and adjusted as additional information is received that impacts the amount reserved. To date, the Company has not experienced material credit-related losses. The provision for doubtful accounts was $ 0.6 million and $ 0.3 million as of December 31, 2021 and 2020, respectively. |
Inventory | Inventory Inventory represents finished goods purchased from a third-party manufacturer and is valued at the lower of cost or net realizable value. Cost is determined using actual costs on a first-in, first-out basis for all inventory. Net realizable value is determined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The Company regularly reviews inventory quantities in consideration of actual loss experiences, projected future demand, and remaining shelf life to record a provision for excess and obsolete inventory when appropriate. The Company’s policy is to write down inventory that has become obsolete, inventory that has a cost basis in excess of its expected lower of cost or net realizable value, and inventory in excess of expected requirements. The estimate of excess quantities is judgmental and primarily dependent on the Company’s estimates of future demand for the particular product. |
Property, Plant and Equipment | Property and Equipment, net Property and equipment are recorded at cost, less accumulated depreciation. Repairs and maintenance costs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, typically two to five years . When assets are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the balance sheet and any resulting gain or loss is reflected in operations in the period realized. Construction-in-process assets consist primarily of tools and equipment that have not yet been placed in service. These assets are stated at cost and are not depreciated. Once the assets are placed into service, assets are reclassified to the appropriate asset class based on their nature and depreciated in accordance with the useful lives above. |
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The Company assesses long-lived assets, including property and equipment, whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable. If indicators of impairment exist, an impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition are less than their carrying amount. Impairment, if any, is measured as the amount by which the carrying amount of the long-lived assets exceeds their fair value. Fair value is determined through various valuation techniques, including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. The Company did no t record any impairment of long-lived assets for the years ended December 31, 2021 and 2020. |
Leases | Leases Contractual arrangements that meet the definition of a lease are classified as operating or finance leases and are recorded on the balance sheets as both a right-of-use asset (“ROU asset”) and lease liability, calculated by discounting fixed lease payments over the lease term at the Company’s incremental borrowing rate (“IBR”). Lease ROU assets and lease obligations are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company currently does not have any finance leases. Operating lease ROU assets are adjusted for (i) payments made at or before the commencement date, (ii) initial direct costs incurred, and (iii) tenant incentives under the lease. As the implicit rates for the operating leases are not determinable, the Company uses an IBR based on the information available at the respective lease commencement dates to determine the present value of future payments. IBR represents the interest rate that the Company would expect to incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis with similar terms and payments, in an economic environment where the leased asset is located. The Company considers a lease term to be the noncancelable period that it has the right to use the underlying asset, including any periods where it is reasonably certain the Company will exercise any option to extend the contract. Lease costs for minimum lease payments for operating leases are recognized on a straight-line basis over the lease term. Lease liabilities are increased by interest and reduced by payments each period, and the ROU asset is amortized over the lease term. Variable lease payments that do not depend on an index or rate are recognized as lease costs when incurred. In measuring the ROU assets and lease liabilities, the Company has elected to combine lease and non-lease components. The Company does not recognize ROU assets or lease liabilities for short-term leases, if any, having initial terms of 12 months or less at lease commencement as an accounting policy election, and recognizes rent expense on a straight-line basis over the lease term for these types of leases. |
Redeemable Convertible Preferred Stock Warrants | Redeemable Convertible Preferred Stock Warrants The Company’s redeemable convertible preferred stock warrants were classified as liabilities as the underlying redeemable convertible preferred stock was considered contingently redeemable and the Company was obligated to transfer assets to the holders upon occurrence of a deemed liquidation event. The warrants were recorded at fair value upon issuance and subject to remeasurement to fair value at each balance sheet date, with changes in fair value recognized as other expense in the statements of operations. The warrants liability was recorded as other noncurrent liabilities in the balance sheets. The Company continued to adjust the warrant liability for changes in fair value until the conversion of redeemable convertible preferred stock into common stock. At the time of conversion, the liability associated with the redeemable convertible preferred stock warrants was converted into warrants to purchase common stock and reclassified to additional paid-in capital. As a result of the conversion in the current year, the redeemable convertible preferred stock warrant liability was settled and will no longer be subject to remeasurement. Redeemable Convertible Preferred Stock The Company recorded its redeemable convertible preferred stock at fair value on the dates of issuance, net of issuance costs. A redemption event will be deemed to have occurred upon the liquidation or winding-up of the Company, a greater than 50% change in control, or sale of substantially all of the assets of the Company. In the event of a change of control of the Company, proceeds received from the sale of such shares will be distributed in accordance with the liquidation preferences set forth in the Company’s amended and restated certificate of incorporation, unless the holders of redeemable convertible preferred stock otherwise agree or have converted their shares into shares of common stock. Therefore, redeemable convertible preferred stock was classified outside of stockholders’ equity in the balance sheets, as events triggering the liquidation preferences are not solely within the Company’s control. During the current year, the holders of the redeemable convertible preferred stock agreed to have their shares converted into shares of common stock. At the time of conversion, the balances were reclassified to common stock and additional paid-in capital. |
Common Stock Warrant | Common Stock Warrant The Company’s common stock warrant is classified in equity as it meets all criteria for equity classification. The fair value of the common stock warrant was calculated using the BackSolve Method and is recorded at fair value upon issuance in additional paid-in capital in the consolidated balance sheets. The common stock warrant is not remeasured after the issuance date. |
Revenue Recognition | Revenue Recognition The Company applies the following five steps in order to determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its arrangements: • Identify the contract with a customer, • Identify the performance obligations in the contract, • Determine the transaction price, • Allocate the transaction price to performance obligations in the contract, and • Recognize revenue as the performance obligations are satisfied. Revenue recognized during the years ended December 31, 2021 and 2020 relates entirely to the sale of the Company’s products within the Surgical Glaucoma and Dry Eye segments. These sales are primarily to hospitals, medical centers, and ECPs throughout the United States through sales representatives and distributors. The Company’s revenue arrangements consist of a single performance obligation. Revenue is recognized at the point in time when control of the promised goods transfer to the Company’s customers. Revenue is measured at the amount of consideration expected to be received in exchange for the transfer of goods. The amount of revenue that is recognized is based on the transaction price, which represented the invoiced amounts and includes estimates of variable consideration, such as discounted, where applicable. The Company does not offer right of return, except in the case where items are defective as manufactured, and the company does not typically provide customers with a right to a refund. The amount of variable consideration included in the transaction price may be constrained and is included only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized under the contract will not occur in a future period. Payment terms, typically 30 days, are offered to customers and do not include a significant financing component. The Company extends credit to customers based upon their financial condition and credit history and generally require no collateral. The Company does not have any contract balances related to product sales. Shipping and handling costs incurred for the delivery of goods to customers are included in cost of goods sold. In cases where the Company bills shipping and handling cost to customers, the Company classifies those amounts in net revenue. As a practical expedient, the Company recognizes the incremental costs of obtaining contracts, such as sales commissions, as an expense when incurred since the amortization period of the asset we otherwise would have recognized is one year or less. Sales commissions are recorded within selling, general, and administrative expenses in the statements of operations. |
Cost Of Goods Sold | Cost of Goods Sold The Company purchases its products from third-party manufacturers. Cost of goods sold consists primarily of costs related to materials, manufacturing overhead costs, reserves for excess, and obsolete and non-sellable inventories. Cost of goods sold also includes depreciation expense for production equipment and certain direct costs, such as shipping and handling costs. |
Research and Development | Research and Development The Company expenses research and development costs as incurred. Research and development expenses consist primarily of product development, clinical studies to develop and support the Company’s products, regulatory expenses, medical affairs, and other costs associated with products and technologies that are in development. Research and development expenses include employee compensation, including stock-based compensation, supplies, consulting, prototyping, testing, materials, travel expenses, depreciation, and an allocation of facility overhead expenses. |
Selling, General and Administrative Expense | Selling, General and Administrative Selling, general and administrative expenses include compensation, employee benefits, and stock-based compensation for executive management, finance administration, and human resources; facility costs (including rent); bad debt costs; professional service fees; and other general overhead costs, including depreciation to support the Company’s operations. |
Advertising Expense | Advertising Expense The Company expenses advertising costs as incurred. Advertising expenses for fiscal years 2021 and 2020 were $ 2.1 million and $ 0.8 million, respectively, included in selling, general, and administrative expenses in the statements of operations and comprehensive loss. |
Accounting for Payroll Protection Program | Accounting for Payroll Protection Program In March 2020, Congress established the Paycheck Protection Program (“PPP”) to provide relief to small businesses during COVID-19 as part of the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. The legislation authorized the U.S. Treasury to use the Small Business Association’s (“SBA’s”) small business lending program to fund forgivable loans that qualifying businesses could spend to cover payroll, mortgage interest, rent, and utilities during the “Covered Period” defined as the 8-week period starting on the date the PPP loan proceeds are received. Upon meeting certain criteria as specified in the PPP program, the loans are eligible for partial or total forgiveness. In May 2020, the Company applied for and received a PPP loan for the amount $ 2.2 million from SBA. The PPP loan was fully forgiven in June 2021. U.S. GAAP does not contain authoritative accounting standards for forgivable loans provided by governmental entities to a for-profit entity. Absent authoritative accounting standards, interpretative guidance issued and commonly applied by financial statement preparers allows for the selection of accounting policies amongst acceptable alternatives. The Company determined it most appropriate to account for the PPP loan proceeds as an in-substance government grant by analogy to International Accounting Standards 20 (“IAS 20”) Accounting for Government Grants and Disclosure of Government Assistance . Under this guidance, a forgivable loan from government is treated as a government grant when there is reasonable assurance that the entity will meet the terms for forgiveness of the loan. While IAS 20 does not define “reasonable assurance”, this concept in practice is analogous to “probable” as defined in Financial Accounting Standards Board (“FASB”) ASC 450-20-20 under U.S. GAAP, which is the definition the Company has applied to its expectations of PPP loan forgiveness. Under IAS 20, government grants are recognized in earnings on a systematic basis over the periods in which the Company recognizes costs for which the grant is intended to compensate (i.e. qualified expenses). Further, IAS 20 permits for the recognition in earnings either separately under a general heading such as other income, or as a reduction of the related expenses. The Company has elected to recognize this government grant income as a reduction of the related expenses, and recognized $ 0.1 million, $ 0.3 million and $ 1.8 million as a reduction of cost of revenue, research and development and selling, general and administrative expenses, respectively for the year ended December 31, 2020. |
Stock-Based Compensation | Stock-Based Compensation The Company measures and records the expense related to stock-based payment awards based on the fair value of those awards as determined on the date of grant. The Company recognizes stock-based compensation expense over the requisite service period of the individual grant, generally equal to the vesting period and uses the straight- line method to recognize stock-based compensation, and accounts for forfeitures as they occur. The Company selected the Black-Scholes-Merton (“Black-Scholes”) option-pricing model as the method for determining the estimated fair value for stock options. The Black-Scholes option-pricing model requires the use of highly subjective and complex assumptions, which determine the fair value of share-based awards, including the option’s expected term, expected volatility of the underlying stock, risk-free interest rate and expected dividend yield. |
Currency Remeasurement | Currency Remeasurement Foreign currency transaction gains and losses are recorded in other expense, net in the Company’s statements of operations and such amounts have not been material for all periods presented. |
Income Tax | Income Taxes The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and the tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Management makes an assessment of the likelihood that the resulting deferred tax assets will be realized. A valuation allowance is provided when it is more likely than not that some portion or all off a deferred tax asset will not be realized. Due to the Company's historical operating performance and the recorded cumulative net losses in prior fiscal periods, the net deferred tax assets have been fully offset by a valuation allowance. The Company recognizes uncertain income tax positions at the largest amount that is more likely than not to be sustained upon audit by relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Changes in recognition or measurement are reflected in the period in which judgment occurs. The Company's policy is to recognize interest and penalties related to the underpayment of income tax as a component of provision for income taxes. |
Comprehensive Income | Comprehensive Loss Comprehensive loss represents all changes in stockholders’ deficit except those resulting from distributions to stockholders. There have been no items qualifying as other comprehensive income (loss) and, therefore, for all periods presented, there was no difference between comprehensive loss and the Company’s reported net loss. |
Net loss per share attributable to common stockholders | Net loss per share attributable to common stockholders Basic and diluted net loss per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The Company considers all series of its redeemable convertible preferred stock and restricted stock awards to be participating securities as the holders are entitled to receive dividends on a pari passu basis in the event that a dividend is paid on common stock. Under the two-class method, the net loss attributable to common stockholders is not allocated to the redeemable convertible preferred stock or restricted stock awards as the holders of the Company’s redeemable convertible preferred stock and restricted stock awards do not have a contractual obligation to share in losses. Basic and diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period without consideration of potentially dilutive securities. The Company’s potentially dilutive shares, which consist of outstanding common stock options, restricted stock awards, common stock warrants, redeemable convertible preferred stock and redeemable convertible preferred stock warrants were excluded in the computation of diluted net loss per share for the period as the result would be anti-dilutive. |
Emerging Growth Company | Emerging growth company and smaller reporting company The Company is an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012, as well as a "smaller reporting company, as defined by the Securities and Exchange Commission per Rule 12b-2 of the Exchange Act. As such the Company is eligible for exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies, including reduced reporting and extended transition periods to comply with new or revised accounting standards for public business entities. The Company has elected to avail themselves of this exemption and, therefore, will not be subject to the timeline for adopting new or revised accounting standards for public business entities that are not emerging growth companies, and will follow the transition guidance applicable to private companies. |
New Accounting Pronouncements Not Yet Adopted | Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available-for-sale debt securities. The guidance is effective for the Company beginning in the first quarter of 2023. The Company is evaluating the impact of adopting this guidance and does not expect to have a material impact on the Company’s financial statements and related disclosures. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , that simplifies the accounting for income taxes by eliminating certain exceptions related to the approach for intra-period tax allocation and modified the methodology for calculating income taxes in an interim period. It also clarifies and simplifies other aspects of the accounting for income taxes. The guidance is effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022 with early adoption permitted. The Company is evaluating the effect of this new guidance and does not expect it to have material impact on the Company’s financial statements. In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. The amendment is effective for all entities through December 31, 2022. LIBOR is used to calculate the interest on borrowings under the Company’s term loan and revolving line of credit with MidCap Financial Services. The Company is evaluating the effect of this new guidance and does not expect it to have material impact on the Company’s financial statements. |
