  • Patent number: 6177032
    Abstract: A laminated light-polarizing composite lens is efficiently produced by bonding a pre-formed polarized sheet to the front convex surface of a molded polycarbonate lens in an autoclave. Excellent optical properties are obtained by the replication from a polished glass surface to the front surface of the lens. The outer surface layer of the finished lens is isotropic and thus does not produce unwanted birefringence effects. The method is especially well suited for the production of optically corrected decentered polycarbonate lenses. The process is simple and easily changed to produce lenses with different base curves and colors.
