ABSTRACT:
Colored contact lenses that are colored by means of interference coatings for cosmetically enhancing or changing the color of the eyes are disclosed. In particular, the interference coating is applied to a surface of the lens material and, although transparent to the cornea and iris anatomy, so that the coating reflects pre-selected bands of the light spectrum to cosmetically change or enhance the natural color or hue of the eye.
