Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business Operations	1. Organization and Business Operations Second Sight Medical Products, Inc. (“Second Sight,” the “Company,” “we,” “us,” “our” or similar terms) has developed, manufactured and marketed implantable visual prosthetics that are intended to deliver useful artificial vision to blind individuals. We are a recognized global leader in neuromodulation devices for blindness, and are committed to developing new technologies to treat the broadest population of sight-impaired individuals. Our principal offices are located in Los Angeles, California. In 2007, Second Sight formed Second Sight Medical Products (Switzerland) Sàrl, initially to manage clinical trials and sales and marketing in Europe, the Middle East and Asia-Pacific, and more recently for the research of future technologies. As the laws of Switzerland require at least two 99.5 0.5 100 Leveraging our 20 years of experience in neuromodulation for vision, we are developing the Orion ® • We have a good safety profile • The efficacy data is encouraging No peer-reviewed data is available yet for the Orion system. We are currently negotiating the clinical and regulatory pathway to commercialization with the FDA as part of the Breakthrough Devices Program. Product and Clinical Development Plans By further developing our visual cortical prosthesis, Orion, we believe we may be able to significantly expand our market to include nearly all profoundly blind individuals. The principal notable exceptions for potential use of the Orion are those who are blind due to otherwise currently treatable diseases, individuals who are born blind, or blindness due to direct damage of the visual cortex, which is rare. However, of the estimated 36 million blind people worldwide, there are approximately 5.8 million people who are legally blind due to causes that are not otherwise treatable. We continue to develop and refine our estimates of the potential addressable market size as we evaluate the commercial prospects for Orion using a combination of published sources, third party market research, and physician feedback. We currently estimate over 500,000 individuals in the US are legally blind due to retinitis pigmentosa, glaucoma, diabetic retinopathy, optic nerve disease and eye injury. Of this population, we estimate the potential US addressable market is between 50,000 and 100,000 individuals with bi-lateral blindness at the light-perception level or worse. Our marketing approvals by the FDA and other regulatory agencies will ultimately determine the subset of these patients who are eligible for the Orion based on our clinical trials and the associated results. Our objective in designing and developing the Orion visual prosthesis system is to bypass the optic nerve and directly stimulate the part of the brain responsible for human vision. A six-subject Early Feasibility Study of the Orion device is currently underway at UCLA and Baylor. Our 24 month results for the six subjects indicate a good safety profile with encouraging efficacy data and benefits in helping subjects perform their daily living tasks. We believe these data results are encouraging and support advancement of Orion into a larger pivotal clinical study. Early promising results are not necessarily indicative of results which may be obtained in our larger Orion clinical trials. In November 2017, the FDA granted Breakthrough Devices Program designation for the Orion. This designation is given to a few select medical devices in order to provide more effective treatment of life-threatening or irreversibly debilitating diseases or conditions. This program is intended to help patients have more timely access to these medical devices by expediting their development, assessment, and review. On February 26, 2021, the U.S. Food and Drug Administration (FDA) approved the Argus 2s Retinal Prosthesis System, a redesigned set of external hardware (glasses and video processing unit) initially for use in combination with previously implanted Argus II systems for the treatment of retinitis pigmentosa (RP). The Company expects that the Argus 2s will be adapted to be the external system for the next generation Orion Visual Cortical Prosthesis System currently under development. In addition to ergonomic improvements, the Argus 2s system offers significantly more processing power, potentially allowing for improved video processing. A decision on when or if to begin production of the newly approved hardware is under evaluation. Liquidity and Capital Resources From inception, our operations have been funded primarily through the sales of our common stock and warrants, as well as from the issuance of debt, convertible debt, research and clinical grants, and limited product revenue generated from the sale of our Argus II product. Funding of our business since 2019 has been primarily provided by: • On June 25, 2021, we closed an underwritten public offering of 11,500,000 5.00 53.3 million • On March 23, 2021, we closed our private placement to seven institutional investors of 4,650,000 6.00 24.5 million • On December 8, 2020, we borrowed $ 1 million • On May 5, 2020, we closed our underwritten public offering of 7,500,000 1.00 6.7 million We were awarded a $ 1.6 million 6.4 million 1.4 million 1.4 million 0.3 million Our financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. We estimate that currently available cash will provide sufficient funds to enable the Company to meet its planned obligations for at least eighteen months. Our ability to continue as a going concern is dependent on our ability to develop profitable operations through implementation of our business initiatives and/or raise additional capital, however, there can be no assurances that we will be able to do so. We were notified by the Nasdaq stock market regarding our non-compliance with one of the continued listing requirements of the Nasdaq Capital Market. We have subsequently satisfied the Nasdaq compliance listing requirement.

Accounting Policies [Abstract]
Basis of Presentation, Significant Accounting Policies and Recent Accounting Pronouncements	2. Basis of Presentation, Significant Accounting Policies and Recent Accounting Pronouncements Basis of Presentation These unaudited interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and following the requirements of the United States Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. In our opinion, the unaudited interim financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial position and our results of operations and cash flows for periods presented. The balance sheet as of December 31, 2020 has been derived from our audited balance sheet included in our annual report on Form 10-K for the year ended December 31, 2020 as filed with the SEC on March 16, 2021. These statements do not include all disclosures required by GAAP and should be read in conjunction with our financial statements and accompanying notes for the fiscal year ended December 31, 2020, contained in our Annual Report on Form 10-K. The results of the interim periods are not necessarily indicative of the results expected for the full fiscal year or any other interim period or any future year or period. Reverse Stock Split On December 31, 2019 we effected a reverse stock split of the outstanding shares of our no par value common stock and outstanding warrants to purchase our common stock by a ratio of 1-for-8 The accompanying consolidated financial statements and notes thereto give retrospective effect to the reverse stock split for all periods presented. All issued and outstanding common stock, options and warrants exercisable for common stock, restricted stock units, and per share amounts contained in our consolidated financial statements have been retrospectively adjusted. Significant Accounting Policies Segment Reporting. On March 31, 2020, due to the COVID-19 pandemic and related inability to secure additional funding, we laid off the majority of our employees and reduced our operating expenses significantly to allow for our continuing business operations. In the six months ended June 30, 2020, due to our focus on Orion and wind down of selling and marketing activities related to Argus II, we recorded impairment charges to our inventory of $ 0.5 million 0.7 million 0.2 million Our significant accounting policies are set forth in Note 2 of the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2020. Recently Issued Accounting Pronouncements We do not believe that any recently issued, but not yet effective, accounting standards, if adopted, will have a material effect on the financial statements.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4. Fair Value Measurements The authoritative guidance with respect to fair value establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels, and requires that assets and liabilities carried at fair value be classified and disclosed in one of three categories, as presented below. Disclosure as to transfers in and out of Levels 1 and 2, and activity in Level 3 fair value measurements, is also required. Level 1. Observable inputs such as quoted prices in active markets for an identical asset or liability that we have the ability to access as of the measurement date. Financial assets and liabilities utilizing Level 1 inputs include active-exchange traded securities and exchange-based derivatives. Level 2. Inputs, other than quoted prices included within Level 1, which are directly observable for the asset or liability or indirectly observable through corroboration with observable market data. Financial assets and liabilities utilizing Level 2 inputs include fixed income securities, non-exchange based derivatives, mutual funds, and fair-value hedges. Level 3. Unobservable inputs in which there is little or no market data for the asset or liability which requires the reporting entity to develop its own assumptions. Financial assets and liabilities utilizing Level 3 inputs include infrequently-traded non-exchange-based derivatives and commingled investment funds, and are measured using present value pricing models. Cash equivalents, which includes money market funds, are the only financial instrument measured and recorded at fair value on our consolidated balance sheet, and they are valued using Level 1 inputs. Assets measured at fair value on a recurring basis are as follows (in thousands) Total Level 1 Level 2 Level 3 June 30, 2021 (unaudited): Money market funds $ 73,818 $ 73,818 $ — $ — December 31, 2020: Money market funds $ 3,122 $ 3,122 $ — $ —

Risk And Uncertainties
Risk and Uncertainties	9. Risk and Uncertainties COVID-19 has directly and indirectly adversely affected Second Sight and will likely continue to do so for an uncertain period of time. In March and April 2020 we laid off a substantial majority of our employees as a result of COVID-19 and an inability to obtain financing. We retained approximately 11 of our employees to oversee current operations. The cumulative effects of COVID-19 on the Company cannot be predicted at this time, but could include, without limitation: • reputational damages of the Company and its products; • inability to raise additional funds to finance and continue our operations; • inability to maintain adequate facilities; • inability to retain and hire experienced personnel; • inability to finalize our plan for and enroll patients into our proposed pivotal clinical trial; • material delays or inability to complete development and commercialization of Orion; • inability to satisfy Nasdaq’s continued listing requirements and exposure to delisting if not remedied; and • other uncertain events that may have negative impact effect on our operations.

Commitments and Contingencies Disclosure [Abstract]
Litigation, Claims and Assessments	10. Litigation, Claims and Assessments Four oppositions filed by Pixium Vision are pending in the European Patent Office, each challenging the validity of a European patent owned by us. The outcomes of the challenges are not certain, however, if successful, they may affect our ability to block competitors from utilizing our patented technology. We believe a successful challenge will not have a material effect on our ability to manufacture and sell our products, or otherwise have a material effect on our operations. As described in the Company’s 10-K for the year ended December 31, 2020, the Company had entered into a Memorandum of Understanding (“MOU”) for a proposed business combination with Pixium Vision SA (“Pixium”). In response to a press release by Pixium dated March 24, 2021, and subsequent communications between us and Pixium, our Board of Directors determined that the business combination with Pixium was not in the best interest of our shareholders. On April 1, 2021, we gave notice to Pixium that we were terminating the MOU between the parties and seeking an amicable resolution of termination amounts that may be due, however no assurance can be given that an amicable resolution will be reached. We accrued $ 1,000,000 1,000,000 5,217,659.60 6,162,760 In November 2020, we and Pixium retained Oppenheimer & Co. Inc. as placement agent for a proposed private placement of securities in connection with the Business Combination. On April 1, 2021, we received an invoice from Oppenheimer for more than $ 1.86 million 6.5 27.9 million On or about July 19, 2021 Martin Sumichrast filed a complaint with the Superior Court of the State of California, County of Los Angeles—Central District, claiming that he is entitled to compensation for services, as well as exemplary and other damages in an amount to be determined at trial but not less than $ 2 million We are party to litigation arising in the ordinary course of business. It is our opinion that the outcome of such matters will not have a material effect on our results of operations, however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These unaudited interim financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and following the requirements of the United States Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. In our opinion, the unaudited interim financial statements have been prepared on the same basis as the audited financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial position and our results of operations and cash flows for periods presented. The balance sheet as of December 31, 2020 has been derived from our audited balance sheet included in our annual report on Form 10-K for the year ended December 31, 2020 as filed with the SEC on March 16, 2021. These statements do not include all disclosures required by GAAP and should be read in conjunction with our financial statements and accompanying notes for the fiscal year ended December 31, 2020, contained in our Annual Report on Form 10-K. The results of the interim periods are not necessarily indicative of the results expected for the full fiscal year or any other interim period or any future year or period.
Reverse Stock Split	Reverse Stock Split On December 31, 2019 we effected a reverse stock split of the outstanding shares of our no par value common stock and outstanding warrants to purchase our common stock by a ratio of 1-for-8 The accompanying consolidated financial statements and notes thereto give retrospective effect to the reverse stock split for all periods presented. All issued and outstanding common stock, options and warrants exercisable for common stock, restricted stock units, and per share amounts contained in our consolidated financial statements have been retrospectively adjusted.
Significant Accounting Policies	Significant Accounting Policies Segment Reporting. On March 31, 2020, due to the COVID-19 pandemic and related inability to secure additional funding, we laid off the majority of our employees and reduced our operating expenses significantly to allow for our continuing business operations. In the six months ended June 30, 2020, due to our focus on Orion and wind down of selling and marketing activities related to Argus II, we recorded impairment charges to our inventory of $ 0.5 million 0.7 million 0.2 million Our significant accounting policies are set forth in Note 2 of the financial statements in our Annual Report on Form 10-K for the year ended December 31, 2020.
