Uv-blocking silicone hydrogel composition and silicone hydrogel contact lens containing thereof

摘要

The present disclosure provides a UV-blocking silicone hydrogel composition including a hydrophilic silicone macromer, a UV-blocking monomer, a first hydrophilic monomer, a crosslinker and a polymerization initiator. The hydrophilic silicone macromer has a general formula: V-L-S-(L'-V') x , wherein V and V' are independently ethylenically-based polymerizable groups, L and L' are independently a covalent bond or a linkage group, S is a siloxane group having a chemical structure such as
or
and x is 0 or 1. A silicone contact lens containing the UV-blocking silicone hydrogel composition is also provided herein.
