Document Type and Number:
WIPO Patent Application WO/2003/035356
Kind Code:
A1
Abstract:
A method for manufacturing a molded plastic lens product which comprises injecting a diethylene glycol bis−allyl carbonate based monomer mixture for a lens into the cavity of a lens mold composed of a sealing member (53) and a mold die (54), allowing the monomer mixture to undergo a cast polymerization, removing the sealing member (53), and cleaning the molded lens product (55), together with the mold die (54), with a detergent comprising a glycol ether and water&semi and a detergent for a plastic lens or a mold die for a plastic lens which comprises a glycol ether and water. The detergent is a novel detergent for use in manufacturing a molded plastic lens and is advantageous over a conventional one in that it is friendly to the environment.
