MONOMER, POLYMER AND OPHTHALMIC LENS USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a monomer for a polymer having high oxygen permeability, high water content and low modulus of elasticity, a polymer composed of the monomer and an ophthalmic lens. SOLUTION: This monomer is characterized by formula (a) [X is a polymerizable carbon-carbon bond-containing group; R is H or a methyl group; A is a siloxanyl group; m is an integer of 2-10; n is an integer of 2-10].
