Abstract
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.
