Contact lens comprising trimethylvinylsilane polymer

摘要

The contact lens of the invention is shaped of a poly(trimethylvinylsilane) resin having an average molecular weight of at least 200,000 or a copolymer based thereon. The contact lens has a very high oxygen permeability comparable to conventional transparent silicone rubbers so as to ensure a long time of continued wearing of the lens on the cornea with no adverse physiological influences and the material still has much better mechanical workability for precision shaping into a lens form than the transparent silicone rubbers.
