SILICONE HYDROGEL, LENS FOR EYE, AND CONTACT LENS

摘要

The present invention provides transparent silicone hydrogels with high acrylamide monomer content and an excellent balance between moisture content. The silicone hydrogels may be obtained by polymerizing a monomer mix containing a plurality of monomers, wherein the monomer mix comprises about 30 to about 98% by weight of at least one type of silicone monomer which is, and about 1 to about 50% by weight of at least one type of non-silicone type (meth)acrylamide monomer containing two or more hydroxyl groups within a molecule; wherein the weight percents are based upon the total amount of monomer components and polymer components in the monomer mix.
