  • Publication number: 20240142664
    Abstract: Two types of blue light blocking contact lenses are provided and are formed by curing different compositions. The first composition includes a blue light blocking component formed by mixing or reacting a first hydrophilic monomer and a yellow dye, a first colored dye component formed by mixing or reacting a second hydrophilic monomer and a first colored dye, at least one third hydrophilic monomer, a crosslinker, and an initiator. The first colored dye includes a green dye, a cyan dye, a blue dye, an orange dye, a red dye, a black dye, or combinations thereof. The second composition includes a blue light blocking component, at least one hydrophilic monomer, a crosslinker, and an initiator. The blue light blocking component is formed by mixing or reacting glycerol monomethacrylate and a yellow dye. Further, methods for preparing the above contact lenses are provided.

  • Patent number: 11198751
    Abstract: The present invention provides a water-soluble silicone macromer. The water-soluble silicone macromer has a general formula: E?(M1)x?(M2)y, wherein M1 is a repeating unit which is derived from a silicone containing monomer, M2 is a repeating unit which is derived from a first hydrophilic monomer, and E is an ethylenically unsaturated group. The amount of M1 is in a range of 30-60 wt % based on the total weight of the water-soluble silicone macromer, and the amount of M2 is in a range of 40-70 wt % based on the total weight of the water-soluble silicone macromer. A silicone hydrogel composition containing the water-soluble silicone macromer and a silicone hydrogel lens made of the silicone hydrogel composition are also provided herein.
