Abstract: Modifications to the surface of polyvinyl alcohol-based films are disclosed that result in improved adhesion to optical materials. Specifically, the surface chemistry of the polyvinyl alcohol-based film is altered to include fluorine bonds, which surprisingly improve direct adhesion of the film to materials such as optical thermoset resins, without the use of additional coatings or multilayer sandwich construction. Embodiments of this invention for incorporation of polarizer films in thermoset resin lenses are described. A method of exposing the film to indirect, reduced-pressure plasma to achieve these surface modifications, and an exemplary holder for the film during such processing, are disclosed.

Abstract: An eyewear lens provides for selective spectral performance in response to varying light conditions, including both changes in intensity and spectral distribution. The lens responds selectively to both ultraviolet and visible light, and exhibits different spectral transmittance characteristics under different lighting conditions, to provide for better vision for a wearer. In addition to this active response, the lens also may include a polarizer to further control light and to minimize the glare that interferes with clear vision.

Abstract: A barrier package for the storage of lens wafers used in fabricating laminated lenses, comprises a package adapted to be sealed to enclose therein a lens wafer and formed of a multilayer material, including a metallic layer, of low moisture transmission rate, so that conditions of humidity inside the sealed package are substantially isolated from humidity conditions external of the package. Lens wafers so stored exhibit minimum distortions to interface curvature. Instead of or in addition to being stored in a barrier package, the lens wafers can also be coated with a moisture barrier coating to achieve isolation from external humidity fluctuations. The moisture equilibrated precision lens wafers are suitable for use in optical devices.
