The method for making an optical lens which includes: filling a molding cavity vertically oriented and defined by two mold pieces at the periphery of which is disposed an annular closure member with a polymerizable synthetic composition through a disposable check valve provided in the closure member; polymerizing the composition to form the lens; and recovering the lens with the disposable check valve imprisoned within the polymerized composition at the periphery thereof.

A method for molding a plastic ophthalmic lens which comprises introducing a liquid polymerizable composition in a molding cavity of a two-piece mold through a filling nozzle in flow communication with the upper half of the molding cavity and spaced apart from the central vertical axis of the molding cavity up to the time the lower half of the molding cavity is filled. Then, tilting the mold to bring the filling in register with the central axis of the molding cavity and achieving full filling of the molding cavity. Thereafter, polymerizing the composition and recovering the lens.

A method that includes providing a cavity defined by at least a portion of a mold and a closure member attached to the portion of the mold, the portion of the mold being oriented vertically and having a top and a bottom, and a sealing material being positioned near the bottom and attached to the closure member; puncturing the sealing material and the closure member with an instrument near the bottom, the puncturing creating an opening in the sealing material; and introducing a polymerizable composition into the cavity through the instrument. A method useful in testing sealing materials. Other methods are also disclosed.

An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.
