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.

Lens with colored portion and coated surface

A method of making a lens, such as a contact lens, with a colored portion involves introducing a lens-forming monomer mixture and a colored material to a lens mold, applying a magnetic field to the monomer mixture and the colored material, whereby the colored material migrates in response to the magnetic field to form a desired pattern, and curing the lens-forming monomer mixture with the colored material forming a desired colored pattern in the lens.

Method of making lens with colored portion

A method of making a lens, such as a contact lens, with a colored portion involves introducing a lens-forming monomer mixture and an ionic colored material to a lens mold, applying an electrical field to the monomer mixture and the colored material, whereby the colored material migrates in response to the electrical field to form a desired pattern, and curing the lens-forming monomer mixture with the colored material forming a desired colored pattern in the lens.
