Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Product Revenue, Net The Company sells its products principally to a limited number of distributors, group purchasing organizations, eye care or health care professionals including independent practices, corporate retailers, hospitals and clinics or authorized resellers (collectively, its Customers). These Customers subsequently resell the Company’s products to eye care or health care providers and patients. In addition to product supply and distribution agreements with Customers, the Company enters into arrangements with health care providers and payors that provide for government-mandated and/or privately-negotiated rebates, chargebacks and discounts with respect to the purchase of the Company’s products. The Company considers customer purchase orders, which in some cases are governed by master sales agreements, to be contracts with a customer. In situations where sales are to a distributor, the Company has concluded that its contracts are with the distributor. As part of its consideration of the contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations. Revenues from product sales are recognized when the Customer obtains control of the Company’s product, which occurs at a point in time, typically upon shipment or delivery to the Customer. When the Company performs shipping and handling activities after the transfer of control to the Customer (e.g., when control transfers prior to delivery), they are considered as fulfillment activities, and accordingly, the costs are accrued for when the related revenue is recognized. Taxes collected from Customers relating to product sales and remitted to governmental authorities are excluded from revenues. The Company does not have any revenue recognized on payment expected to be received more than one year after the transfer of control of the products. The Company expenses incremental costs of obtaining a contract as and when incurred if the expected amortization period of the asset that the Company would have recognized is one year or less.

Reserves for Variable Consideration Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established and which result from discounts, returns, chargebacks, rebates and other allowances that are offered within contracts between the Company and its Customers, health care providers, payors and other indirect customers relating to the Company’s sales of its products. These reserves are based on the amounts earned or to be claimed on the related sales and are classified primarily in current liability. Variable consideration is estimated based on the most likely amount or expected value approach, depending on which method the Company expects to better predict the amount of consideration to which it will be entitled. Once the Company elects one of the methods to estimate variable consideration for a particular type of performance obligation, the Company will apply that method consistently. Where appropriate, these estimates take into consideration a range of possible outcomes which are probability-weighted for relevant factors such as the Company’s historical experience, current contractual and statutory requirements, specific known market events and trends, industry data and forecasted customer buying and payment patterns. Overall, these reserves reflect the Company’s best estimates of the amount of consideration to which it is entitled based on the terms of the contract.

Trade Discounts and Allowances The Company generally provides Customers with discounts, which include incentive fees that are stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. In addition, the Company receives sales order management, data and distribution services from certain Customers. To the extent the services received are distinct from the Company’s sale of products to the Customer and have readily determinable fair value, these payments are classified in selling, general and administrative expenses in the consolidated statements of income of the Company.
