ABSTRACT OF THE DISCLOSURE A hydrophilic silicone contact lens can be produced by pouring into a mold a silicone resin monomer, heating the monomer to effect polymerization, processing the resulting formed product into a lens, and then irradiating the surface of the lens with a low temperature gas plasma to impart hydrophilic pro- perty to the surface of the lens. Further, in order that the hydrophilic property can be maintained for a long period of time even if the lens is allowed to stand in the air, a hydrophilic resin film may be formed on the thus irradiated surface of the lens.
