Abstract
There is disclosed a method for making colored hydrophilic contact lenses. A contact lens constructed of hydrophilic polymer that is substantially devoid of the functional groups --COOH, --OH, --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, --NCO and epoxy is provided. At least a portion of the surface of the lens is coated with a color coat comprising at least one pigment, binding polymer having functional groups selected from at least one of --COOH, --OH, and --NH--R, wherein R is hydrogen or C.sub.1 to C.sub.8 alkyl, and an additional compound having at least two groups per molecule of --NCO. The coated lens is subjected to conditions which cause the color coat to adhere to the lens.
