Abstract
A lens with a colored portion is composed of a lens-forming polymer having a front lens surface and a back lens surface. A colorant is applied to at least one of these surfaces, and these surfaces may be coated with a coating layer composed of a material different than the lens-forming polymer. In the case of a cosmetic contact lens, the colorant may be applied in an annular ring pattern corresponding to an iris, so that the colorant pattern masks and changes the apparent color of the natural iris when the contact lens is worn.
