摘要： The instant invention pertains to a method and a fluid composition for producing contact lenses with relatively high edge quality and with relatively high precision and fidelity in reproducing a desired lens design. The method of the invention involves: a mold which has a first mold half with a first molding surface and a second mold half with a second molding surface, wherein the first and second mold halves are configured to receive each other such that the cavity is formed between the first and second molding surfaces which define the opposite two surfaces of a contact lens to be produced; a spatial limitation of actinic radiation to define the edge of the contact lens to be produced; and addition of a radical scavenger in a fluid composition comprising a lens-forming material to reduce substantially the crosslinking/polymerizing, caused by diffused, scattered and/or reflected incident actinic radiation, of the fluid composition outside of and around the spatial limitation of actinic radiation.

摘要： The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves applying to a molding surface of the mold a layer of mold releasing agent selected from a group consisting of fatty amines of carbon chain length C18 or less and silicones bearing pendant substituted pyrrolidone groups solution to reduce an averaged mold separation force by at least about 50% in comparison with that without the releasing agent.
