ABSTRACT:
A polymerization product suitable for contact lenses comprising (a) an organosiloxane monomer having the following general formula ##STR1## wherein n is an integer of 1 to 3, X is --(CH.sub.2).sub.p --O].sub.q in which p is an integer of 2 to 4 and q is 0 or an integer of 1 to 3, and Y.sup.1, Y.sup.2 and Y.sup.3 are methyl group or --O--Si--(CH.sub.3).sub.3, and (b) a hydrophobic methacrylic acid alkyl ester monomer. The polymerization product and cross-linked polymerization product have excellent oxygen permeability and proper hydrophilic property and are substantially water-nonabsorptive, and contact lenses made thereof can be comfortably worn continuously for a long period of time.
