  • Eyeglass lens having improved heat resistance and scratch resistance
    Patent number: 10054715
    Abstract: An aspect of the present invention relates to an eyeglass lens comprising a lens substrate and a vapor-deposited film either directly or indirectly on the lens substrate, wherein the vapor-deposited film is an oxide film of metal selected from the group consisting of zirconium and tantalum, with an average grain size observed in a planar image obtained by a transmission electron microscope of equal to or greater than 3.5 nm and a proportion accounted for by grain boundaries, which are boundaries separating grains from regions outside of the grains, in a planar image obtained by a transmission electron microscope of less than 15%.
    Type: Grant
    Filed: September 30, 2013
    Date of Patent: August 21, 2018
    Assignee: HOYA CORPORATION
    Inventors: Nobuyuki Tadokoro, Naomi Ogawa, Makoto Adachi, Yuko Komine, Koushi Harada
  • Eyeglass lens
    Patent number: 9927557
    Abstract: An aspect of the present invention relates to an eyeglass lens comprising a lens substrate and a vapor-deposited film either directly or indirectly on the lens substrate, wherein the vapor-deposited film is an oxide film of metal selected from the group consisting of zirconium and tantalum, with a proportion accounted for by regions observed in a streaky shape, in a columnar shape, or in a lump shape in a cross-sectional image of the vapor-deposited film obtained by a transmission electron microscope of equal to or less than 20%.
    Type: Grant
    Filed: September 30, 2013
    Date of Patent: March 27, 2018
    Assignee: HOYA CORPORATION
    Inventors: Nobuyuki Tadokoro, Naomi Ogawa, Makoto Adachi, Yuko Komine, Koushi Harada
  • Method of manufacturing eyeglass lens
    Patent number: 9651802
    Abstract: An aspect of the present invention relates to a method of manufacturing an eyeglass lens, comprising determining a manufacturing condition by a method of determining a manufacturing condition of an eyeglass lens comprising a vapor-deposited film formed by vapor deposition using a vapor deposition source the main component of which is ZrO2, and forming a vapor-deposited film by vapor deposition using a vapor deposition source the main component of which is ZrO2 under the manufacturing condition that has been determined.
