本发明提供一种阻隔紫外光的硅水胶组成物，此硅水胶组成物包含亲水硅胶高聚物、阻隔紫外光单体、第一亲水性单体、交联剂及聚合反应起始剂。亲水硅胶高聚物具有如通式(1)所示之化学结构：V-L-S-(L’-V’)x(1)，其中V及V’分别独立为一乙烯基可聚合基团，L及L’分别独立为一共价键或一键结基团，S为一硅氧烷基团具有化学结构：或，及x为0或1。一种包含阻隔紫外光的硅水胶组成物的硅水胶镜片亦揭露于此。

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.
