ABSTRACT:
Apparatus for the coloring or tinting of one or more selected areas of a soft or flexible contact lens to precise measurements comprises a support means formed to closely match one of the surfaces of the lens and a mask means adapted to operatively associate with the support means to delineate said one or more selected areas by providing one or more peripheral zones of compression within the lens to prevent the migration of an applied coloring or tinting medium thereacross. In use the lens is positioned on the support means so that one of the surfaces thereof closely matches the support means, the mask means is arranged to provide one or more peripheral zones of compression delineating said one or more selected areas, and a coloring or tinting medium is applied to at least one selected area.
