Abstract
A formulation for silicone hydrogel for use in contact lens includes at least one silicone monomer having a weight percent of the total hydrogel weight in a range from about 10% to about 35%, at least one hydrophilic monomer having a weight percent of the total hydrogel weight in a range from about 15% to about 40%, at least one crosslinker, and at least one initiator. A silicone hydrogel, and a method to form silicone hydrogel are provided.
