Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization and Basis of Presentation	Note 1 – Organization and Basis of Presentation Description of Business RxSight®, Inc. (the “Company”) is a Delaware corporation headquartered in Aliso Viejo, California with two wholly owned subsidiaries. One subsidiary is located in Amsterdam, Netherlands, with registered branches in the United Kingdom and Ireland. The Ireland registered branch was closed in 2020. The Netherlands entity also has a wholly owned subsidiary in Germany. A second subsidiary located in Tijuana, Mexico was also closed in 2020. The Company is engaged in the research and development, manufacture and sale of light adjustable intraocular lenses used in cataract surgery along with capital equipment used with the lenses. The Company’s products, which include the light adjustable lens (“LAL”®) and a specially designed machine for delivering light to the eye, the Light Delivery Device (“LDD™”), are approved by the United States (“U.S.”) Food and Drug Administration (“FDA”) for sale in the U.S. and have regulatory approval in the U.S and Europe. The Company began marketing its products in the U.S. during the second quarter of 2019 and in Europe during the third quarter of 2019. The LAL is a premium intraocular lens (“IOL”) which is partially reimbursable under Medicare. The Company competes with other IOLs in the premium market in the U.S. and Europe. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of RxSight, Inc. and its wholly-owned subsidiaries, RxSight, B.V., located in the Netherlands, and RxSight GmbH, located in Germany. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. All significant inter-company balances and transactions have been eliminated in consolidation. Initial Public Offering (“IPO”) and Reverse Stock Split On July 22, 2021, the Company’s Board of Directors approved an amendment to the Company’s certificate of incorporation to effect a reverse split of shares of the Company’s common stock, excluding Series G and Series W common stock, and convertible preferred stock on a 1-for-10.33 basis (the “Reverse Stock Split”). The par values of the common stock and convertible preferred stock were not adjusted as a result of the Reverse Stock Split. The Reverse Stock Split was effected on July 23, 2021. Accordingly, all common stock, excluding Series G and Series W common stock, options to purchase common stock, convertible preferred stock, share data, per share data and related information contained in the accompanying condensed consolidated financial statements and notes have been retrospectively adjusted to reflect the effect of the Reverse Stock Split for all periods presented. Outstanding stock options were proportionately reduced and the respective exercise prices, if applicable, were proportionately increased. The Reverse Stock Split resulted in an adjustment to the convertible preferred stock conversion prices to reflect a proportional decrease in the number of shares of common stock to be issued upon conversion. On July 29, 2021, the Company completed the IPO through an underwritten sale of 7,350,000 shares of its common stock at a price of $16.00 per share. The aggregate net proceeds from the offering, inclusive of an additional 898,549 common shares sold upon the partial exercise of the underwriters’ over-allotment option, after deducting underwriting discounts and commissions of $9.2 million and other offering costs of $3.2 million, were approximately $120.0 million. On July 29, 2021, the Company restated its certificate of incorporation and bylaws which provide for, among other things, the Company’s authorized capital stock to consist of 900,000,000 shares of common stock, par value $0.001 per share, and 100,000,000 shares of convertible preferred stock, par value $0.001 per share. The restated certificate defines the voting rights, dividends, liquidation, rights and preferences of each class of stock. Immediately prior to the completion of the IPO, 14,376,272 outstanding shares of the Company's convertible preferred stock were converted into an aggregate of 14,725,309 shares of common stock and 225,945 warrants to purchase Series H convertible preferred stock were exercised and converted into 100,261 shares of common stock. Liquidity and Financial Position As of December 31, 2021, the Company has cash, cash equivalents and short-term investments of $159.3 million. The Company began generating revenue from its principal operations in June 2019. The Company has a limited operating history, and the revenue and income potential of the Company’s business and market are unproven. The Company has experienced recurring net losses and negative cash flows from operating activities since its inception. For the years ended December 31, 2021 and 2020, the Company incurred losses from operations of $52.8 million and $35.4 million, respectively. Due to the Company’s continuing research and development activities and investment in sales and marketing activities to increase product market acceptance, the Company expects to continue to incur net operating losses into the foreseeable future. Successful transition to attaining profitable operations is dependent upon gaining market acceptance of the Company’s products and achieving a level of revenues adequate to support the Company’s cost structure. The accompanying financial statements have been prepared assuming the Company will continue as a going concern. The Company believes that existing capital resources, including the net proceeds from the IPO in July 2021, will be sufficient to meet projected operating requirements for at least 12 months from the date of issuance of the accompanying consolidated financial statements, though the Company expects to continue to incur operating losses and negative cash flows. The Company plans to continue to fund its losses from operations using its cash, cash equivalents and short-term investments as of December 31, 2021 and meet its future capital funding needs through equity or debt financings, other third-party funding, collaborations, strategic alliances and licensing arrangements or a combination of these. If the Company raises additional funds by issuing equity securities, its stockholders may experience dilution. Any future debt financing into which the Company enters may impose additional covenants that restrict operations, including limitations on its ability to incur liens or additional debt, pay dividends, repurchase common stock, make certain investments or engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity raise may contain terms that are not favorable to the Company or its stockholders. If the Company is required to enter into collaborations and other arrangements to address its liquidity needs, it may have to give up certain rights that limit its ability to develop and commercialize product candidates or may have other terms that are not favorable to the Company or its stockholders, which could materially and adversely affect its business and financial prospects. There can be no assurance that the Company will be able to obtain additional financing on acceptable terms, or at all. If the Company is not able to secure adequate additional funding, the Company may be forced to make reductions in spending, extend payment terms with suppliers, liquidate assets where possible and/or suspend or curtail planned programs. Any of these actions could materially harm the Company’s business, results of operations and future prospects. COVID-19 The Company has been actively monitoring the novel coronavirus, or COVID-19, situation and its impact. In response to the pandemic, numerous state and local jurisdictions imposed “shelter-in-place” orders, quarantines and other restrictions. Starting in March 2020 in the United States, governmental authorities recommended, and in certain cases required, that elective, specialty and other procedures and appointments be suspended or canceled. Similarly, in March 2020, the governor of California, where the Company’s headquarters is located, issued “stay at home” orders limiting non-essential activities, travel and business operations. Such orders and restrictions resulted in reduced operations at the Company’s headquarters, slowdowns and delays, travel restrictions and cancellation of events. These orders and restrictions significantly decreased the number of procedures performed using the Company’s products starting in March of 2020 and continuing through 2021. In response to the impact of COVID-19, the Company implemented a variety of measures to help manage through the impact and position it to resume operations quickly and efficiently once these restrictions were lifted. These measures included: remote work as needed, suspension of non-essential travel, restrictions on in-person work-related meetings, the wearing of personal protective equipment, social distancing, increased facility cleaning and air purification in all of the Company’s buildings and daily health monitoring of all Company employees to prevent or contain COVID-19 exposure. In addition, the Company took steps to preserve liquidity, reduce expenses and monitor operations to mitigate the impact on its current and future financial condition. The impact of COVID-19 continues to evolve and its impact on the Company’s business will depend on several factors that are highly uncertain and unpredictable, including, the efficacy and adoption of vaccines, future resurgences of the virus and its variants, the speed at which government restrictions are lifted, patient capacity at hospitals and healthcare systems, the duration and severity of healthcare worker shortages, and the willingness and ability of patients to seek care and treatment due to safety concerns or financial hardship.

COVID-19

The Company has been actively monitoring the novel coronavirus, or COVID-19, situation and its impact. In response to the pandemic, numerous state and local jurisdictions imposed “shelter-in-place” orders, quarantines and other restrictions. Starting in March 2020 in the United States, governmental authorities recommended, and in certain cases required, that elective, specialty and other procedures and appointments be suspended or canceled.
