Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited financial statements for all periods presented, including the historical results of the Company prior to May 10, 2022, are referred to as “Condensed Consolidated Financial Statements”, and have been prepared by the Company in United States (“U.S.”) dollars and in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and pursuant to the rules and regulations for reporting on Form 10-Q, which do not conform in all respects to the requirements of U.S. GAAP for annual financial statements. Accordingly, certain information and disclosures required by U.S. GAAP for complete Consolidated Financial Statements are not included herein. Accordingly, these notes to the unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements prepared in accordance with U.S. GAAP that are contained in the Company’s Annual Report. The unaudited Condensed Consolidated Financial Statements have been prepared using accounting policies that are consistent with the policies used in preparing the Company’s audited Consolidated Financial Statements for the year ended December 31, 2022. The unaudited Condensed Consolidated Financial Statements reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position and results of operations for the interim periods. The operating results for the interim periods presented are not necessarily indicative of the results expected for the full year. Prior to the B+L IPO, Bausch + Lomb had historically operated as part of BHC; therefore, separate financial statements were not historically prepared. The accompanying unaudited Condensed Consolidated Financial Statements for periods prior to the B+L IPO were prepared from BHC’s historical accounting records. Prior to the B+L IPO, Bausch + Lomb relied on BHC’s corporate and other support functions. Therefore, certain corporate and shared costs for periods prior to the B+L IPO had been allocated to Bausch + Lomb. Refer to Note 2 in the Company’s Annual Report for additional details on the Company's basis of presentation during the periods prior, and subsequent, to the B+L IPO. Following the B+L IPO, certain functions that BHC provided to Bausch + Lomb prior to the B+L IPO were provided and, in some cases, continue to be provided to Bausch + Lomb by BHC under a Transition Services Agreement (the “TSA”) or are performed using Bausch + Lomb’s own resources or third-party service providers. Bausch + Lomb has incurred certain costs in its establishment as a standalone public company, and expects additional ongoing costs associated with operating as an independent, publicly traded company.
Use of Estimates	Use of Estimates In preparing the Company’s Condensed Consolidated Financial Statements, management is required to make estimates and assumptions. This includes estimates and assumptions regarding the nature, timing and extent of the impacts that certain global macroeconomic conditions, including, but not limited to, those related to the COVID-19 pandemic and other macroeconomic factors, including those related to inflation and supply chain, will have on the Company's operations and cash flows. The estimates and assumptions used by the Company affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates made by management include: provisions for product returns, rebates, chargebacks, discounts and allowances and distribution fees paid to certain wholesalers; useful lives of finite-lived intangible assets and property, plant and equipment; expected future cash flows used in evaluating intangible assets for impairment, assessing compliance with debt covenants, reporting unit fair values for testing goodwill for impairment; acquisition-related contingent consideration liabilities; provisions for loss contingencies; provisions for income taxes, uncertain tax positions and realizability of deferred tax assets; the fair value of cross-currency swaps; and the fair value of foreign currency exchange contracts. Prior to the B+L IPO, significant estimates made by management also included the related allocations described in the basis of presentation. All estimates in these Condensed Consolidated Financial Statements are based on assumptions that management believes are reasonable. On an ongoing basis, management reviews its estimates to ensure that these estimates appropriately reflect changes in the Company's business and new information as it becomes available. If historical experience and other factors used by management to make these estimates do not reasonably reflect future activity, the Company's business, financial condition, cash flows and results of operations could be materially impacted. The extent to which certain global macroeconomic conditions, including, but not limited to, those related to the COVID-19 pandemic and its overall impact on inflation and supply chain, may continue to impact the Company’s business, financial condition, cash flows and results of operations, in particular, will depend on future developments which are highly uncertain and many of which are outside the Company’s control. The Company has assessed the possible effects and outcomes of these macroeconomic conditions on, among other things, its supply chain, customers and distributors, discounts and rebates, employee base, product sustainability, research and development efforts, product pipeline and consumer demand and currently believes that its estimates are reasonable.

Revenue Recognition	Revenue Recognition The Company’s revenues are primarily generated from product sales in the therapeutic areas of eye health that consist of: (i) branded prescription eye-medications and pharmaceuticals, (ii) generic and branded generic prescription eye medications and pharmaceuticals, (iii) OTC vitamin and supplement products and (iv) medical devices (contact lenses, IOLs and ophthalmic surgical equipment). Other revenues include alliance and service revenue from the licensing and co-promotion of products and contract service revenue. Contract service revenue is derived primarily from contract manufacturing for third parties and is not material. See Note 18, “SEGMENT INFORMATION” for the disaggregation of revenues which depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by the economic factors of each category of customer contracts. The Company recognizes revenue when the customer obtains control of promised goods or services and in an amount that reflects the consideration to which the Company expects to be entitled to receive in exchange for those goods or services. To achieve this core principle, the Company applies the five-step revenue model to contracts within its scope: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. Product Sales A contract with the Company’s customers exists for each product sale. Where a contract with a customer contains more than one performance obligation, the Company allocates the transaction price to each distinct performance obligation based on its relative standalone selling price. The transaction price is adjusted for variable consideration which is discussed further below. The Company recognizes revenue for product sales at a point in time, when the customer obtains control of the products in accordance with contracted delivery terms, which is generally upon shipment or customer receipt. Contracted delivery terms will vary by customer and geography. In the U.S., control is generally transferred to the customer upon receipt. Revenue from sales of surgical equipment and related software is generally recognized upon delivery and installation of the equipment. IOLs and delivery systems, disposable surgical packs and other surgical instruments are distinct from the surgical equipment and may be sold together with the surgical equipment in a single contract or on a standalone basis. Revenue from the sale of delivery systems, disposable surgical packs and other surgical instruments is recognized in accordance with the contracted delivery terms, generally upon shipment or customer receipt. IOLs are sold primarily on a consignment basis and revenue is recognized upon notification of use, which typically occurs when a replacement order is placed. When a sale transaction in the Surgical segment contains multiple performance obligations, the transaction price is allocated to each performance obligation based on the relative standalone sales price and revenue is recognized upon satisfaction of each performance obligation. Product Sales Provisions As is customary in the eye health industry, gross product sales of certain product categories are subject to a variety of deductions in arriving at reported net product sales. The transaction price for such product categories is typically adjusted for variable consideration, which may be in the form of cash discounts, allowances, returns, rebates, chargebacks and distribution fees paid to customers. Provisions for variable consideration are established to reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract. The amount of variable consideration included in the transaction price may be constrained, and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in the future period. Provisions for these deductions are recorded concurrently with the recognition of gross product sales revenue and include cash discounts and allowances, chargebacks and distribution fees, which are paid to direct customers, as well as rebates and returns, which can be paid to direct and indirect customers. Returns provision balances and volume discounts to direct customers are included in Accrued and other current liabilities. All other provisions related to direct customers are included in Trade receivables, net, while provision balances related to indirect customers are included in Accrued and other current liabilities.
