Summary:A colour contact lens is composed of the first and the second lens layers and a colour layer between them. It is prepared through pouring monomer material in mould to form the first lens layer by rotation or casting method, printing colour layer on it to form iris pattern, pouring same monomer material in the mould to form the second lens layer, and water treating. Its advantages are smooth surface, strong stereo feeling, not decolouring and no irritation to eye ball.
