US Patent 11905351 Silicone hydrogel materials

A composition includes at least one siloxy-based (meth)acrylate monomer or prepolymer, at least one additional methacrylate monomer, UV, and Visible light blocking agents and one or more crosslinking agents. The final product results in a highly wettable material that possesses physical properties such as a low modulus of elasticity and high oxygen permeability without the need for a non-reactive solubilizing agent and that are free of cyclic and linear siloxanes.
