摘要 |
A substantially non-crosslinked water-absorptive soft ocular lens material obtained by polymerizing polymerizable components comprising a methoxysilane compound (A) of the formula (I): X-Z-Si(OCH3)n(R1)3-n (I) wherein X is a (meth)acryloyloxy group, a vinyl group, a group of the formula <IMAGE> or an allyl group, Z is a direct bond or a C1-3 alkylene group, R1 is a C1-6 alkyl group, and n is an integer of from 1 to 3, and a hydrophilic monomer (B) which has an unsaturated double bond copolymerizable with the methoxysilane compound (A) and which undergoes no crosslinking reaction, in an amount of at least 45 mol %.
