▎ 摘  要

NOVELTY - The method involves taking a bare chip to be endowed with anti-UV radiation-proof contact lens. A coating layer is coated on a surface of the bare chip, where the coating layer includes a graphene. A layer of colorless protective coating is covered on the processed coating. The processed coating is cured to obtain a non-hydrated colored contact lens. The color contact lens is repeatedly put into the salt water with pH 7 to stabilize until the expansion rate is not changed. The contact lens is put into a bottle. Wet steam sterilization is performed on the contact lens to obtain a final anti-UV anti-radiation contact lens, where the bare chip is selected as colorful dry sheet, a material of the colorless protective coating is selected as hydrogel, silicon gel fluorine gel, solute is selected as N-methyl pyrrolidone, dimethyl formamide, dimethyl acetamide and acetone, dispersant is silane coupling agent. USE - Method for manufacturing anti-UV anti-radiation contact lens. ADVANTAGE - The method enables realizes the anti-radiation function by directly coating the surface of the bare chip.
