  • Patent number: 8710167
    Abstract: 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.
