HYDROPHILIC COLORED CONTACT LENSES

摘要

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 C1 to C8 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 C1 to C8 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.
