ABSTRACT:
The invention is a cosmetic contact lens that changes the apparent color of the eye. The cosmetic lens is made from a cosmetic contact lens blank comprising a colored transparent polymer disk having a cone shaped central segment. A liquid lens monomer containing a dye which visibily fluoresces by the light of day is cast over the cone shaped central segment. The daylight fluorescent monomer is polymerized to form a daylight fluorescent polymer. A clear liquid lens monomer is cast on the flat surface of the daylight fluorescent polymer and polymerized to form a solid monolithic cosmetic lens blank. A concave contact lens curve is cut through the clear polymer layer and through the daylight fluorescent colored layer and into the cone shaped colored transparent layer. The size of the lens pupil and iris area is controlled by the depth the concave contact lens surface is cut into the central cone shaped transparent blank segment. A convex contact lens curve which intersects the three blank layers is cut to form the cosmetic contact lens. The cosmetic lens has a transparent colored pupil area surrounded by the daylight fluorescent iris area that changes the apparent color of the eye and is surrounded by a clear transparent peripheral area.
