<p>A method for making hydrophilic contact lenses, in which a contact lens is produced, constructed of hydrophilic polymer that is substantially devoid of the functional groups -COOH, -OH, -NH-R, where R is hydrogen or C1 to C8 alkyl, -NCO and epoxy. At least a portion of the surface of the lens is then coated with a colour coat comprising at least one pigment, a binding polymer having functional groups selected from at least one of -COOH, -OH, and -NH- R, where 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 colour coat to adhere to the lens.</p> |
