  • Patent number: 11124676
    Abstract: A method for manufacturing an optical member which can improve bonding properties between a first member having a light transmitting property and a second member. The method includes a precuring step of forming a photocuring precured resin layer on a surface of the first member or the second member, the photocuring precured resin layer having a thin film on a side to be bonded with the second member or the first member, a bonding step of bonding the first member and the second member via the precured resin layer, and a final curing step of final-curing the precured resin layer to form a light transmitting resin layer. It is thereby possible to reduce the elastic modulus of the precured resin layer, suppress protrusion during bonding, and improve bonding properties.

  • Patent number: 11067831
    Abstract: Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.
