Accounting Policies [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Nature of Operations National Vision Holdings, Inc. (“NVHI,” the “Company,” “we,” “our,” or “us”) is a holding company whose operating subsidiaries include its indirect wholly owned subsidiary, National Vision, Inc. (“NVI”) and NVI’s direct wholly owned subsidiaries. We are a leading value retailer of eyeglasses and contact lenses in the United States and its territories. We operated 1,145 and 1,082 retail optical locations as of September 28, 2019 and December 29, 2018 , respectively, through our five store brands, including America’s Best Contacts and Eyeglasses (“America’s Best”), Eyeglass World, Vista Optical locations on U.S. Army/Air Force military bases (“Military”) and within Fred Meyer stores, and our management and services arrangement with Walmart (“Legacy”). Basis of Presentation We prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and, therefore, do not include all information and disclosures required by U.S. GAAP for complete consolidated financial statements. The condensed consolidated balance sheet as of December 29, 2018 has been derived from the audited consolidated balance sheet for the fiscal year then ended. These condensed consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 28, 2019 , the consolidated results of operations and comprehensive income, the statements of changes in stockholders’ equity for the three and nine months ended September 28, 2019 and September 29, 2018 , and its statements of cash flows for the nine months ended September 28, 2019 and September 29, 2018 . Certain information and disclosures normally included in our annual consolidated financial statements have been condensed or omitted; however, we believe that the disclosures included herein are sufficient for a fair presentation of the information presented. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the fiscal year ended December 29, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2019. The Company’s significant accounting policies are set forth in Note 1 within those consolidated financial statements. We use the same accounting policies in preparing interim condensed consolidated financial information and annual consolidated financial statements. There were no changes to our significant accounting policies during the nine months ended September 28, 2019 , except for the adoption of Accounting Standards Update (“ASU”) 2016-02, Leases. See “Adoption of New Accounting Pronouncements” below for further discussion. The condensed consolidated financial statements include our accounts and those of our subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation. Fiscal Year Our fiscal year consists of 52 or 53 weeks ending on the Saturday closest to December 31. Fiscal year 2019 contains 52 weeks and will end on December 28, 2019 . All three and nine month periods presented herein contain 13 and 39 weeks, respectively. All references to years and quarters relate to fiscal periods rather than calendar periods. Seasonality The consolidated results of operations for the three and nine months ended September 28, 2019 and September 29, 2018 are not necessarily indicative of the results to be expected for the full fiscal year due to seasonality and uncertainty of general economic conditions that may impact our key end markets. Historically, our business has realized a higher portion of net revenue, income from operations, and cash flows from operations in the first fiscal quarter, and a lower portion of net revenue, income from operations, and cash flows from operations in the fourth fiscal quarter. The seasonally larger first quarter is attributable primarily to the timing of our customers’ personal income tax refunds and annual health insurance program start or reset periods. Seasonality related to fourth quarter holiday spending by retail customers generally does not impact our business. Our quarterly consolidated results may also be affected by the timing of new store openings, store closings, and certain holidays. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Asset Impairment We evaluate impairment of long-lived tangible and right of use (“ROU”) store assets at the store level, which is the lowest level at which independent cash flows can be identified, when events or conditions indicate the carrying value of such assets may not be recoverable. In making this evaluation, we may consider multiple factors including financial performance of the stores, regional and local business climates, future plans for the store operations and other qualitative factors. If the store's projected undiscounted net cash flows expected to be generated by the related assets over the shorter of the remaining useful life or the remaining term of the lease are less than the carrying value of the subject assets, we then measure impairment based on a discounted cash flow model and market-based indications of value of the ROU asset and record an impairment charge as the excess of carrying value over estimated fair value. As directed in the accounting guidance for long-lived assets held and used, we use entity-specific assumptions related to our anticipated use of the assets when developing the projected undiscounted cash flows. We identified indicators of impairment of certain stores and recorded $3.5 million and $7.4 million of related asset impairment charges during the three and nine months ended September 28, 2019 , respectively, in Corporate/Other. These impairment charges were primarily driven by lower than projected customer sales volume in certain stores. The estimated fair value of the impaired assets was $14.6 million as of September 28, 2019 ; this value includes fair value estimates related to impairments recorded in the first and second quarters of 2019. The cash flows used in the estimation were discounted to fair value using a rate of 8% . A significant decrease in the estimated cash flows would lead to a lower fair value measurement, as would a significant increase in the discount rate. The market-based indications of value of ROU assets were based on third-party information without adjustment. These measurements were classified as Level 3 measurements in the fair value hierarchy. Income Taxes Our income tax rate for the three months ended September 28, 2019 reflected our statutory federal and state rate of 25.6% , offset by a discrete benefit of $6.3 million associated primarily with stock option exercises. Our income tax benefit for the nine months ended September 28, 2019 reflected income tax expense at our statutory federal and state rate of 25.6% , offset by a discrete benefit of $7.7 million associated primarily with stock option exercises. In comparison, the income tax rate associated with the three and nine months ended September 29, 2018 was reduced by $13.9 million and $18.0 million respective income tax benefit resulting from stock option exercises. Secondary Offering and Common Stock Repurchase On August 7, 2019, the Company entered into an Underwriting Agreement by and among the Company, KKR Vision Aggregator L.P. (the “Selling Stockholder”), and Goldman Sachs & Co. LLC, as underwriter (the “Underwriter”), relating to an underwritten offering of 9,149,908 shares of the Company’s common stock, par value $0.01 per share. The offering was completed on August 12, 2019. In connection with the offering, our Board of Directors authorized, and the Company completed, a repurchase of 819,134 shares out of the 9,149,908 shares of common stock subject to the offering from the Underwriter at $30.52 per share, which was the price the Underwriter purchased the shares from the Selling Stockholder in the offering. The Company did not receive any proceeds from the offering. As a result of this underwritten offering and concurrent share repurchase, the Selling Stockholder no longer owns any shares of our common stock as of September 28, 2019 . The secondary offering constituted a vesting event whereby a final portion of the performance-based options vested and the remaining portion of unvested performance options awarded under the 2014 Stock Incentive Plan was forfeited. Refer to Note 5. “Stock Incentive Plans.” for further information on stock based compensation activity for the nine months ended September 28, 2019. As a result of the offering, we incurred $4.2 million of non-cash stock-based compensation expense during the three months ended September 28, 2019 . We additionally recorded $1.1 million in long-term cash incentive compensation expense and $0.4 million in offering related expenses in selling, general and administrative (“SG&A”) during the three months ended September 28, 2019 . Adoption of New Accounting Pronouncements Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases . This new guidance establishes a ROU model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with such classification affecting the pattern of expense recognition in the statement of operations. Disclosure of key information about leasing arrangements is also required. We adopted ASU No. 2016-02, as amended, as of December 30, 2018 (the first day of fiscal year 2019 ), using the modified retrospective transition approach without adjusting the comparative periods presented. We elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward historical lease classification for leases in existence as of the adoption date, to not assess whether any expired or existing contracts are leases or contain leases and to not assess whether unamortized initial direct costs for existing leases meet the definition of initial direct costs. In addition, we elected the practical expedients to not separate lease components from non-lease components and to not apply this new guidance to leases with terms of less than 12 months. Upon adoption, we recorded operating lease liabilities of approximately $349.7 million as of December 30, 2018 . The Company treated tenant improvement allowances (“TIAs”) and deferred rent of $28.6 million and $11.9 million , respectively, as of December 30, 2018 as reductions of lease payments used to measure ROU assets and recorded $308.5 million of lease ROU assets upon adoption. The difference between the additional lease assets and lease liabilities net of the deferred tax impact was $0.5 million , which was recorded as an adjustment to fiscal year 2019 opening retained earnings. Adoption of this new guidance did not result in significant changes to our results of operations or cash flows. See Note 8 . “Leases” for additional information. Future Adoption of Accounting Pronouncements Cloud Computing. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This new guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years and may be adopted on a prospective or retrospective basis. The Company is in the process of assessing the new guidance. Credit Losses . In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This new guidance requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Initial adoption of ASU 2016-13 is required to be reported on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption, except for certain provisions that are required to be applied prospectively. This guidance is effective for fiscal years beginning after December 15, 2019, and for interim reporting periods within those fiscal years. The Company is in the process of assessing the new guidance.

Fair Value Measurements of Fina

Fair Value Measurements of Financial Assets and Liabilities	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements of Financial Assets and Liabilities	The Company uses a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect pricing based upon a reporting entity’s own market assumptions. The Company is required to measure certain assets and liabilities at fair value or disclose the fair values of certain assets and liabilities recorded at cost. Accounting standards define fair value as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated assuming the transaction occurs in the principal or most advantageous market for the asset or liability and includes consideration of non-performance risk and credit risk of both parties. A three-tier fair value hierarchy prioritizes the inputs used in measuring fair value. These tiers include: • Level 1 - Valuation inputs are based upon unadjusted quoted prices for identical instruments traded in active markets. • Level 2 - Valuation inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the instruments. • Level 3 - Valuation inputs are unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are determined using model-based techniques that include discounted cash flow models and similar techniques. The fair value estimates of financial instruments are not necessarily indicative of the amounts we might pay or receive in actual market transactions. The use of different market assumptions and/or estimation methodologies may have a material impact on the estimated fair value amounts. Cash, Cash Equivalents and Restricted Cash The carrying amount of cash and cash equivalents approximates fair value due to the short-term maturity of the instruments. All cash and cash equivalents are denominated in U.S. currency. Accounts Receivable, Net The carrying amount of accounts receivable approximates fair value due to the short-term nature of those items and the effect of related allowances for doubtful accounts. Accounts Payable and Other Payables and Accrued Expenses The carrying amounts of accounts payable and other payables and accrued expenses approximate fair value due to the short-term nature of those items. Long-term Debt - Term Loan and Revolving Credit Facility Since the borrowings under the Term Loan (as defined below) and revolving credit facility utilize variable interest rate setting mechanisms such as LIBOR, the fair values of these borrowings are deemed to approximate the carrying values. Refer to Note 4 . “Long-term Debt” for additional information on the Term Loan and revolving credit facility. Finance Lease Obligations The fair value of finance lease obligations is based on estimated future contractual cash flows discounted at an appropriate market rate of interest (Level 2 inputs). The estimated fair values of our finance leases were $39.4 million and $30.7 million as of September 28, 2019 and December 29, 2018 , respectively, compared to carrying values of $34.2 million and $24.5 million , respectively. Interest Rate Derivatives The Company is party to three pay-fixed and receive-floating interest rate swap agreements to offset the variability of cash flows in LIBOR-indexed debt interest payments, subject to a 1.0% floor, attributable to changes in the benchmark interest rate from March 13, 2017 to March 13, 2021 related to its credit agreement. During the first quarter of 2019 , in accordance with the original agreements with the counterparties, the notional amount of the first derivative decreased from $140.0 million to $105.0 million . There were no other changes in the terms of the arrangements. We recognize as assets or liabilities at fair value the estimated amounts we would receive or pay upon a termination of interest rate swaps prior to their scheduled expiration dates. Fair value is based on information that is model-driven and whose inputs are observable (Level 2 inputs). Cumulative unrealized losses on derivative instruments are recorded in accumulated other comprehensive loss (“AOCL”), net of tax. As of September 28, 2019 , the Company expects to reclassify $4.7 million of unrealized losses on derivative instruments, net of tax, from AOCL into earnings in the next 12 months as the derivative instruments mature. See Note 12 . “Accumulated Other Comprehensive Loss” for further details. Changes in the cash flows of each derivative are expected to be highly effective in offsetting the changes in interest payments on a principal balance equal to the derivative’s notional amount, attributable to the hedged risk. Our hedges have been deemed highly effective since inception as a result of our quarterly hedge effectiveness testing. Our cash flow hedge position related to interest rate derivative contracts is as follows: In thousands Notional Amount Maturity Date Other Payables and Accrued Expenses Other Liabilities AOCL, Net of Tax (1) As of $ 430,000 March 2021 $ 6,260 $ 3,214 $ 4,921 As of $ 465,000 March 2021 $ 3,130 $ 3,505 $ 2,810 (1) Includes stranded tax benefit of $2.1 million within AOCL from adopting provisions of the Tax Cuts and Jobs Act of 2017 during the year ended December 30, 2017.

Revenue from Contract with Customer [Abstract]
Revenue From Contracts with Customers	Revenue from Contracts with Customers The Company’s revenues are recognized either at the point of sale or upon delivery and customer acceptance, paid for at the time of sale in cash, credit card, or on account with managed care payors having terms generally between 14 and 120 days , with most paying within 90 days . Our point in time revenues include 1) retail sales of prescription and non-prescription eyewear, contact lenses and related accessories to retail customers (including those covered by managed care), 2) eye exams and 3) wholesale sales of inventory in which our customer is another retail entity. Revenues recognized over time primarily include product protection plans, eye care club memberships and management fees earned from our legacy partner. The following disaggregation of revenues is based on the timing of revenue recognition: Three Months Ended Nine Months Ended In thousands September 28, 2019 September 29, 2018 September 28, 2019 September 29, 2018 Revenues recognized at a point in time $ 394,709 $ 352,245 $ 1,211,942 $ 1,075,355 Revenues recognized over time 37,193 35,180 110,626 105,577 Total net revenue $ 431,902 $ 387,425 $ 1,322,568 $ 1,180,932 Refer to Note 10 . “Segment Reporting” for the Company’s disaggregation of net revenue by reportable segment. As the reportable segments are aligned by similar economic factors, trends and customers, the reportable segment disaggregation view best depicts how the nature, amount and uncertainty of revenue and cash flows are affected by economic factors. Contract Assets and Liabilities The Company’s contract assets and contract liabilities primarily result from timing differences between the performance of our obligations and the customer’s payment. Accounts Receivable Accounts receivable associated with revenues consist primarily of trade receivables and credit card receivables. Trade receivables consist primarily of receivables from managed care payors and receivables from major retailers. While we have relationships with almost all vision care insurers in the United States and with all of the major carriers, currently, a relatively small number of payors comprise the majority of our managed care revenues, subjecting us to concentration risk. Trade receivables and credit card receivables are included in accounts receivable, net, on our condensed consolidated balance sheets, and are presented separately in Note 2 . “Details of Certain Balance Sheet Accounts.” Accounts receivable are reduced by allowances for amounts that may become uncollectible. Estimates of our allowance for uncollectible accounts are based on our historical and current operating, billing, and collection trends. Impairment losses (i.e., bad debt expense) recognized on our receivables were approximately $2.4 million and $6.3 million for the three and nine months ended September 28, 2019 , respectively, and $1.7 million and $5.0 million for the three and nine months ended September 29, 2018 , respectively. Unsatisfied Performance Obligations (Contract Liabilities) Our retail customers generally make payments for prescription eyewear products at the time they place an order. Amounts we collect in advance for undelivered merchandise are reported as unearned revenue in the accompanying condensed consolidated balance sheets. Unearned revenue at the end of a reporting period is estimated based on delivery times throughout the current month and generally ranges from four to 10 days . All unearned revenue at the end of a reporting period is recognized in the next fiscal period. Our contract liabilities also consist of deferred revenue on services and plans obligations, primarily product protection plans and eye care club memberships. The unamortized portion of amounts we collect in advance for these services and plans is reported as deferred revenue in the accompanying condensed consolidated balance sheets (current and non-current portions). Our deferred revenue balance as of September 28, 2019 was $79.3 million . We expect future revenue recognition of this balance of $20.3 million , $42.2 million , $13.4 million , $3.2 million , and $0.2 million in fiscal years 2019 , 2020 , 2021 , 2022 , and thereafter , respectively. We recognized $27.9 million and $83.2 million of previously deferred revenues during the three and nine months ended September 28, 2019 , respectively and $26.5 million and $78.5 million during the three and nine months ended September 29, 2018 , respectively.

Leases

Leases [Abstract]
Leases	Leases We lease our stores, laboratories, distribution centers, and corporate offices. These leases generally have noncancellable lease terms of between five and 10 years , with an option to renew for additional terms of one to 10 years or more. The lease term includes renewal option periods when the renewal is deemed reasonably certain after considering the value of the leasehold improvements at the end of the noncancellable lease period. Most leases for our stores provide for a minimum rent and typically include escalating rent over time with the exception of Military for which lease payments are variable and based on a percentage of sales. For Vista Optical locations in Fred Meyer stores, we pay fixed rent plus a percentage of sales after certain minimum thresholds are achieved. The Company’s leases generally require us to pay insurance, real estate taxes and common area maintenance expenses, substantially all of which are variable and not included in the measurement of the lease liability. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company does not consider its management and services agreement with its legacy partner to contain a lease arrangement. Our lease arrangements include TIAs, which are contractual amounts received from a lessor for improvements made to leased properties by the Company. For operating leases, TIAs are treated as a reduction of the lease payments used to measure the ROU assets in the accompanying consolidated balance sheet as of September 28, 2019 (non-current liabilities as of December 29, 2018 ), and are amortized as a reduction in rental expense over the life of the respective leases. For finance leases, a lease ROU asset is recorded as property and equipment and corresponding amounts are recorded as finance lease debt obligations at an amount equal to the lesser of the net present value of minimum lease payments to be made over the lease term or the fair value of the property for leases in existence as of fiscal year end 2018 and at the net present value of the minimum lease payments to be made over the lease term for new finance leases entered into subsequent to fiscal year end 2018 . We rent or sublease certain parts of our stores to third parties. Our sublease portfolio consists mainly of operating leases with our ophthalmologists and optometrists within our stores.

We used the incremental borrowing rate on December 30, 2018, for operating leases that commenced prior to that date. (a) TIA of $34.2 million and deferred rent of $14.2 million are treated as reductions of lease payments used to measure ROU assets as of September 28, 2019.

As a majority of our leases are five-year and 10-year leases, we determined a lease discount rate for such tenors and determined this discount rate is reasonable for leases that were entered into during the period. (b) The discount rate on finance leases is higher than operating leases because the present value of minimum lease payments was higher than the fair value of leased properties for certain leases entered into prior to adoption of ASC 842.

These costs were approximately $18.0 million , $14.9 million and $13.9 million during the fiscal years ended 2018 , 2017 and 2016 , respectively.
Leases	Leases We lease our stores, laboratories, distribution centers, and corporate offices. These leases generally have noncancellable lease terms of between five and 10 years , with an option to renew for additional terms of one to 10 years or more. The lease term includes renewal option periods when the renewal is deemed reasonably certain after considering the value of the leasehold improvements at the end of the noncancellable lease period. Most leases for our stores provide for a minimum rent and typically include escalating rent over time with the exception of Military for which lease payments are variable and based on a percentage of sales. For Vista Optical locations in Fred Meyer stores, we pay fixed rent plus a percentage of sales after certain minimum thresholds are achieved. The Company’s leases generally require us to pay insurance, real estate taxes and common area maintenance expenses, substantially all of which are variable and not included in the measurement of the lease liability. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The Company does not consider its management and services agreement with its legacy partner to contain a lease arrangement. Our lease arrangements include TIAs, which are contractual amounts received from a lessor for improvements made to leased properties by the Company. For operating leases, TIAs are treated as a reduction of the lease payments used to measure the ROU assets in the accompanying consolidated balance sheet as of September 28, 2019 (non-current liabilities as of December 29, 2018 ), and are amortized as a reduction in rental expense over the life of the respective leases. For finance leases, a lease ROU asset is recorded as property and equipment and corresponding amounts are recorded as finance lease debt obligations at an amount equal to the lesser of the net present value of minimum lease payments to be made over the lease term or the fair value of the property for leases in existence as of fiscal year end 2018 and at the net present value of the minimum lease payments to be made over the lease term for new finance leases entered into subsequent to fiscal year end 2018 . We rent or sublease certain parts of our stores to third parties. Our sublease portfolio consists mainly of operating leases with our ophthalmologists and optometrists within our stores.

(a) TIA of $34.2 million and deferred rent of $14.2 million are treated as reductions of lease payments used to measure ROU assets as of September 28, 2019.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Other Agreements In the fourth quarter of 2018, the Company renewed an eyeglass lenses supply agreement with a trade vendor effective June 2019. The Company also renewed certain other agreements with the vendor, including a cloud computing service arrangement. As a result, as previously disclosed, this arrangement includes minimum purchase commitments of approximately $30.0 million over the four year term. Additionally, during the nine months ended September 28, 2019 , we entered into minimum purchase commitments with our trade vendors of approximately $17.0 million annually through 2021. Legal Proceedings From time to time, the Company is involved in various legal proceedings incidental to its business. Because of the nature and inherent uncertainties of litigation, we cannot predict with certainty the ultimate resolution of these actions and, should the outcome of these actions be unfavorable, the Company’s business, financial position, results of operations or cash flows could be materially and adversely affected. The Company reviews the status of its legal proceedings and records a provision for a liability when it is considered probable that both a liability has been incurred and the amount of the loss can be reasonably estimated. This review is updated periodically as additional information becomes available. If either or both of the criteria are not met, we reassess whether there is at least a reasonable possibility that a loss, or additional losses, may be incurred. If there is a reasonable possibility that a loss may be incurred, we disclose the estimate of the amount of the loss or range of losses, or that an estimate of loss cannot be made. The Company expenses its legal fees as incurred. On January 29, 2016 , FirstSight, our wholly-owned specialized health maintenance organization, was named as a defendant in a proposed class action filed on behalf of all persons who paid for an eye examination from an optometrist at a Walmart location in California from November 5, 2009 through the date of the resolution of the litigation. The complaint alleges in particular that FirstSight participated in arrangements that caused the illegal delivery of eye examinations to the plaintiffs, and that FirstSight thereby violated, among other statutes, the Unfair Competition and False Advertising laws of California. In March 2017 , the Court granted a motion to dismiss previously filed by FirstSight. The plaintiffs filed an appeal to the U.S. Court of Appeals for the Ninth Circuit in April 2017. In July 2018, the U.S. Court of Appeals for the Ninth Circuit vacated in part, and reversed in part, the district court’s dismissal and remanded for further proceedings. In October 2018, the plaintiffs filed a second amended complaint with the district court seeking, among other claims, unspecified damages and attorneys’ fees, and in November 2018, FirstSight filed a motion to dismiss. The Company believes that the claims are without merit and intends to continue to vigorously defend the litigation. In May 2017 , a complaint (the “1-800 Contacts Matter”) was filed against the Company and other defendants alleging, on behalf of a proposed class of consumers who purchased contact lenses online, that 1-800 Contacts, Inc. entered into a series of agreements with the other defendants, including AC Lens, the Company’s subsidiary, to suppress certain online advertising and that each defendant thereby engaged in anticompetitive conduct in violation of the Sherman Antitrust Act. The Company has settled the 1-800 Contacts Matter for $7.0 million , without admitting liability. Accordingly, the Company recorded a charge for this amount during the second quarter of fiscal year 2017. On November 8, 2017 , the court in the 1-800 Contacts Matter entered an order preliminarily approving the settlement agreement, subject to a settlement hearing. Pursuant to this order, the Company deposited 50% of the settlement amount, or $3.5 million , into an escrow account, to be distributed subject to and in accordance with the terms of the settlement agreement and any further order of the court. In February 2019 , we were served with a lawsuit by a former employee who alleges, on behalf of himself and a proposed class, several violations of California wage and hour laws and seeks unspecified alleged unpaid wages, monetary damages, injunctive relief and attorneys’ fees. On March 21, 2019, we removed the lawsuit from state court to the United States District Court for the Northern District of California. The plaintiff moved to remand the action to state court on April 18, 2019, and the Court denied this motion on July 8, 2019. On July 22, 2019, the plaintiff filed an amended complaint. On July 26, 2019, the parties filed a joint stipulation wherein the Company denied all claims in the amended complaint but joined the plaintiff in seeking a stay of further proceedings in the lawsuit based on the parties’ agreement to attend early mediation in an effort to avoid further costs and expenses of protracted litigation. Mediation has been scheduled in the first quarter of 2020. The Company continues to believe that the plaintiff’s amended complaint lacks merit and will vigorously defend the litigation.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting The Company provides its principal products and services through two reportable segments: Owned & Host and Legacy. The “Corporate/Other” category includes the results of operations of our other operating segments, AC Lens and FirstSight, as well as corporate overhead support. The “Reconciliations” category represents other adjustments to reportable segment results necessary for the presentation of consolidated financial results in accordance with U.S. GAAP. The following is a summary of certain financial data for each of our segments. Reportable segment information is presented on the same basis as our condensed consolidated financial statements, except for net revenue and associated costs applicable to revenue, which is presented on a cash basis, including point of sales for managed care payors and excluding the effects of unearned and deferred revenue, consistent with what the chief operating decision maker (“CODM”) regularly reviews. Asset information is not included in the following summary since the CODM does not regularly review such information for the reportable segments. Our reportable segment profit measure is earnings before interest, tax, depreciation and amortization (“EBITDA”), or net revenue, less costs applicable to revenue, less selling, general and administrative costs. Depreciation and amortization, asset impairment, litigation settlement and other corporate costs that are not allocated to the reportable segments, including interest expense and debt issuance costs are excluded from segment EBITDA. There are no transactions between our reportable segments. We measure assets in our reportable segments on the same basis as consolidated assets. There have been no changes from prior periods in the measurement methods used to determine reportable segment profit or loss, and there have been no asymmetrical allocations to segments. As the reportable segments are aligned by similar economic factors, trends and customers, this disaggregation view best depicts how the nature, amount, and uncertainty of revenue and cash flows are affected by economic factors.

During the nine months ended September 28, 2019 , sales associated with our legacy partner arrangement represented 9.3% of consolidated net revenue. This exposes us to concentration of customer risk.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted average common shares outstanding for the period and includes the dilutive impact of potential new common shares issuable upon vesting and exercise of stock options and vesting of restricted stock units.

	Sep. 28, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation We prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and, therefore, do not include all information and disclosures required by U.S. GAAP for complete consolidated financial statements. The condensed consolidated balance sheet as of December 29, 2018 has been derived from the audited consolidated balance sheet for the fiscal year then ended. These condensed consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 28, 2019 , the consolidated results of operations and comprehensive income, the statements of changes in stockholders’ equity for the three and nine months ended September 28, 2019 and September 29, 2018 , and its statements of cash flows for the nine months ended September 28, 2019 and September 29, 2018 . Certain information and disclosures normally included in our annual consolidated financial statements have been condensed or omitted; however, we believe that the disclosures included herein are sufficient for a fair presentation of the information presented. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the fiscal year ended December 29, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 27, 2019. The Company’s significant accounting policies are set forth in Note 1 within those consolidated financial statements. We use the same accounting policies in preparing interim condensed consolidated financial information and annual consolidated financial statements. There were no changes to our significant accounting policies during the nine months ended September 28, 2019 , except for the adoption of Accounting Standards Update (“ASU”) 2016-02, Leases. See “Adoption of New Accounting Pronouncements” below for further discussion. The condensed consolidated financial statements include our accounts and those of our subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year Our fiscal year consists of 52 or 53 weeks ending on the Saturday closest to December 31. Fiscal year 2019 contains 52 weeks and will end on December 28, 2019 . All three and nine month periods presented herein contain 13 and 39 weeks, respectively. All references to years and quarters relate to fiscal periods rather than calendar periods.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Asset Impairment	Asset Impairment We evaluate impairment of long-lived tangible and right of use (“ROU”) store assets at the store level, which is the lowest level at which independent cash flows can be identified, when events or conditions indicate the carrying value of such assets may not be recoverable. In making this evaluation, we may consider multiple factors including financial performance of the stores, regional and local business climates, future plans for the store operations and other qualitative factors. If the store's projected undiscounted net cash flows expected to be generated by the related assets over the shorter of the remaining useful life or the remaining term of the lease are less than the carrying value of the subject assets, we then measure impairment based on a discounted cash flow model and market-based indications of value of the ROU asset and record an impairment charge as the excess of carrying value over estimated fair value. As directed in the accounting guidance for long-lived assets held and used, we use entity-specific assumptions related to our anticipated use of the assets when developing the projected undiscounted cash flows.
Income Taxes	Income Taxes Our income tax rate for the three months ended September 28, 2019 reflected our statutory federal and state rate of 25.6% , offset by a discrete benefit of $6.3 million associated primarily with stock option exercises. Our income tax benefit for the nine months ended September 28, 2019 reflected income tax expense at our statutory federal and state rate of 25.6% , offset by a discrete benefit of $7.7 million associated primarily with stock option exercises. In comparison, the income tax rate associated with the three and nine months ended September 29, 2018 was reduced by $13.9 million and $18.0 million respective income tax benefit resulting from stock option exercises.
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-02, Leases . This new guidance establishes a ROU model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases are classified as either finance or operating, with such classification affecting the pattern of expense recognition in the statement of operations. Disclosure of key information about leasing arrangements is also required. We adopted ASU No. 2016-02, as amended, as of December 30, 2018 (the first day of fiscal year 2019 ), using the modified retrospective transition approach without adjusting the comparative periods presented. We elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward historical lease classification for leases in existence as of the adoption date, to not assess whether any expired or existing contracts are leases or contain leases and to not assess whether unamortized initial direct costs for existing leases meet the definition of initial direct costs. In addition, we elected the practical expedients to not separate lease components from non-lease components and to not apply this new guidance to leases with terms of less than 12 months. Upon adoption, we recorded operating lease liabilities of approximately $349.7 million as of December 30, 2018 . The Company treated tenant improvement allowances (“TIAs”) and deferred rent of $28.6 million and $11.9 million , respectively, as of December 30, 2018 as reductions of lease payments used to measure ROU assets and recorded $308.5 million of lease ROU assets upon adoption. The difference between the additional lease assets and lease liabilities net of the deferred tax impact was $0.5 million , which was recorded as an adjustment to fiscal year 2019 opening retained earnings. Adoption of this new guidance did not result in significant changes to our results of operations or cash flows. See Note 8 . “Leases” for additional information. Future Adoption of Accounting Pronouncements Cloud Computing. In August 2018, the FASB issued ASU No. 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. This new guidance aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This new guidance is effective for fiscal years beginning after December 15, 2019, and for interim periods within those fiscal years and may be adopted on a prospective or retrospective basis. The Company is in the process of assessing the new guidance. Credit Losses . In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This new guidance requires an entity to assess impairment of its financial instruments based on its estimate of expected credit losses. Initial adoption of ASU 2016-13 is required to be reported on a modified retrospective basis, with a cumulative-effect adjustment to retained earnings as of the beginning of the year of adoption, except for certain provisions that are required to be applied prospectively. This guidance is effective for fiscal years beginning after December 15, 2019, and for interim reporting periods within those fiscal years. The Company is in the process of assessing the new guidance.

We used the incremental borrowing rate on December 30, 2018, for operating leases that commenced prior to that date. (a) TIA of $34.2 million and deferred rent of $14.2 million are treated as reductions of lease payments used to measure ROU assets as of September 28, 2019.

(b) Includes costs for insurance, real estate taxes and common area maintenance expenses, which are variable as well as lease costs above minimum thresholds for Fred Meyer stores and lease costs for Military stores. (c) Income from sub-leasing of stores includes rental income from operating lease properties to ophthalmologists and optometrists who are independent contractors.
Schedule of Lease Terms and Discount Rate	Lease Term and Discount Rate As of Weighted average remaining lease term (months) Operating leases 82 Finance leases 91 Weighted average discount rate (a) Operating leases 4.6 % Finance leases (b) 13.1 % (a) The discount rate used to determine the lease assets and lease liabilities was derived upon considering (i) incremental borrowing rates on our long-term debt; (ii) fixed rates we pay on our interest rate swaps; (iii) LIBOR margins for issuers of similar credit rating; (iv) borrowing rates on five-year and ten-year US Treasuries; and (v) effect of collateralization. As a majority of our leases are five-year and 10-year leases, we determined a lease discount rate for such tenors and determined this discount rate is reasonable for leases that were entered into during the period. (b) The discount rate on finance leases is higher than operating leases because the present value of minimum lease payments was higher than the fair value of leased properties for certain leases entered into prior to adoption of ASC 842. The discount rate differential for those leases is not material to our results of operations.

Segment Reporting [Abstract]
Schedule of Financial Data by Segment	The following is a summary of certain financial data for each of our segments. Reportable segment information is presented on the same basis as our condensed consolidated financial statements, except for net revenue and associated costs applicable to revenue, which is presented on a cash basis, including point of sales for managed care payors and excluding the effects of unearned and deferred revenue, consistent with what the chief operating decision maker (“CODM”) regularly reviews. Asset information is not included in the following summary since the CODM does not regularly review such information for the reportable segments. Our reportable segment profit measure is earnings before interest, tax, depreciation and amortization (“EBITDA”), or net revenue, less costs applicable to revenue, less selling, general and administrative costs. Depreciation and amortization, asset impairment, litigation settlement and other corporate costs that are not allocated to the reportable segments, including interest expense and debt issuance costs are excluded from segment EBITDA. There are no transactions between our reportable segments. We measure assets in our reportable segments on the same basis as consolidated assets. There have been no changes from prior periods in the measurement methods used to determine reportable segment profit or loss, and there have been no asymmetrical allocations to segments. As the reportable segments are aligned by similar economic factors, trends and customers, this disaggregation view best depicts how the nature, amount, and uncertainty of revenue and cash flows are affected by economic factors.
