ABSTRACT:
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.
