摘要： It is an object of the present invention to provide an ocular lens superior in the wettability of the surface thereof, hydrating properties, oxygen permeability, flexibility, elasticity, transparency and shape recoverability though it has a composition using a silicone-containing monomer. The present invention relates to a highly oxygen-permeable hydrated ocular lens obtained by saponifying a copolymer prepared from a specific both-terminal (meth)acryl polydimethylsiloxane, a vinyl carboxylate, a (meth)acrylamide type monomer, a vinyl type crosslinking agent, one or both of a (meth)acrylate having a tertiary structure and a (meth)acrylate having a cyclic structure as (meth)acrylates each having a bulky structure at its side chain and a monomer copolymerizable with these compounds.
