Abstract:
In order to provide a silicone hydrogel which has high uniformity in polymerization rates of polymerization components used for copolymerization, excellent mechanical characteristics, excellent optical characteristics and good shape recoverability and in order to also provide various medical devices and ocular lenses having an excellent balance among elasticity, wettability and transparency, the present invention provides a silicone hydrogel which has a repeating unit derived from a monofunctional linear silicone (meth)acrylate and a repeating unit derived from a hydrophilic (meth)acrylate, and wherein the content of the repeating units derived from (meth)acrylates is more than 80% by mass.
