Abstract

An opaque contact lens comprises a lens body constructed of polymer and solid latex polymer particles directly bound to at least a portion of a surface of the lens, and is produced by reacting the polymer lens body with a latex emulsion at a temperature of from 35 DEG C to 150 DEG C for from 30 to 90 minutes. The latex emulsion may be applied to the lens body by a transfer printing method in combination with a colouring ink to produce an opaque coloured lens.
