More Information
Summary:Colored contact lenses are produced by providing a contact lens constructed of polymer and coating at least a portion of the lens with coloring substance and binding polymer. The lens and binding polymers are bonded to each other by the reaction of functional groups selected from at least one of -COOH, -OH, and -NH-R, wherein R is hydrogen or alkyl, with functional groups selected from at least one of -NCO and epoxy.
