    摘要: A method of rounding the edge of spin cast contact lenses by cutting a concave peripheral curve which intersects both the concave and convex lens surfaces and the lens mold. The lens material polishes away at a slower rate than the mold material providing an uneveness between the lens edge and the mold and provides a rounded contour on the lens edge.

    摘要: A method of making bifocal resinous lenses by providing a positioning cylinder connected to a low refractive index polymer. Cutting a convex optical surface orientated to the positioning cylinder. A high index polymer is cast on the low index optical surface and a second shorter radius convex optical surface which intersects both the high and low refractive index materials is cut and polished. Additional low index polymer is cast over the second shorter radius surface and polymerized. A bifocal lens blank is cut from the polymer mass having the high refractive index surfaces orientated to the exterior blank surfaces.

    摘要: The invention relates to a method of spin casting lenses having optical surfaces which may be spherical, aspherical or toric in shape. The method provides a concave optical mold having a spherical, aspherical or toric optical surface. A convex optical mold having a spherical, aspherical or toric surface is also privided. A selected liquid lens monomer with a selected catalyst is placed in the concave lens mold. The convex optical mold is positioned in the concave mold displacing the liquid lens monomer. The optical axis of the concave and convex molds are aligned and the two molds rotated about their concurrent optical axis. The liquid monomer is allowed to polymerize forming a solid polymer lens. The finished lens is then removed from the molds.

    摘要: The invention is a method of metering liquid lens monomer on to the surface of a concave spin casting mold. This is done by an atomized liquid spray applied to the mold optical surface for a precise time. An inert gas such as nitrogen is used to propel the atomized spray from the spray nozzle to the optical mold surface. The atomized spray wets the optical surface evenly reducing the contact angle to the receding angle. The duration of the spray can be precisely timed by an electronic timer valve. The volume of monomer deposited can be precisely controlled therefore the lens thickness is precisely controlled.

    摘要: A cosmetic contact lens that changes the apparent color of the eye. The lens will change a dark brown eye to light blue or green. This color change is accomplished by having a transparent dyed iris area on the convex lens surface. A light reflecting material is precipitated in the iris area of the concave lens surface. The light colored precipitated iris area on the concave surface may be opaque. The lens pupil area is clear colorless transparent or a dyed transparent color. The peripheral lens area outside the iris area is always clear transparent. When the lens is viewed on the eye the light reflecting concave iris area is viewed through the convex transparent iris color area providing the apparent eye color change.
