There is the silicone hydrogel contact lenses of the energy loss of acceptable level

The present invention describes the silicone hydrogel contact lenses with the energy loss of acceptable level on ophthalmology.Described eyeglass is derived from the polymerisable compound comprising the first siloxanyl monomers represented by formula (1): m in its Chinese style (1) represents the integer of 3 to 10, and the n in formula (1) represents the integer of 1 to 10, the R in formula (1) 1 the alkyl with 1 to 4 carbon atoms, and each R in formula (1) 2 be hydrogen atom or methyl independently; Described eyeglass also comprises the unit derived from the second siloxanyl monomers, the dimethyl silicone polymer of described second siloxanyl monomers to be number average molecular weight be at least 7,000 daltonian pair of terminal methacrylate end-blocking.When the complete hydration of described silicone hydrogel contact lenses, the average loss of energy of described eyeglass is about 30% to about 45%.The present invention also describes the silicone hydrogel contact lenses of multiple batches and prepares the method for silicone hydrogel contact lenses.
