Abstract
Abstract The invention is a cosmetic contact lens that alters the apparent color of the eye. The lens has a thin layer of dye on the convex surface. The dye being the color of the desired color change. Below the surface dye layer is a deeper layer of light reflecting material. The opaque light reflecting material is a light color and is placed behind the dyed transparent surface layer. When the lens is in place on the eye the light reflecting layer is viewed through the transparent dyed surface layer to provide the apparent eye color change.
