摘要： The invention provides a system and method for plasma coating of an optical lens, particularly lenses made of silicone-containing polymer. A system of the invention comprises an entry chamber, a coating chamber downstream from the entry chamber, and an exit chamber downstream from the coating chamber. The coating chamber includes a pair of spaced apart electrodes disposed therein. A system of the invention is configured in a way so that a lens may enter, pass through and exit the system without requiring the coating chamber to be repeatedly pressurized and depressurized.

摘要： A contact lens and a method for manufacturing thereof are provided. The contact lens has a silicone contact lens base material and an amorphous carbon film formed in the silicone contact lens base material. The amorphous carbon film of the contact lens is formed by subjecting the silicone contact lens base material to a plasma polymerization under an atmosphere of a mixed gas comprising a hydrocarbon gas and an oxygen-containing gas. The contact lens has excellent oxygen permeability and a high refractive index.
