Patent number: 10718961Abstract: An aspect of the present invention relates to a spectacle lens including a multilayer film of a vapor deposition film (excluding a metal film and a metal alloy film) directly or indirectly at least on one surface of a lens substrate. The multilayer film includes at least one high refractive index layer and at least one low refractive index layer, the total optical film thickness of the high refractive index layer is ?/4 or more at a wavelength ?=780 nm, and a reflection spectrum measured in a wavelength range of 380 to 2000 nm on a surface having the multilayer film has a maximum reflectance in a wavelength range of 800 to 1350 nm.Type: GrantFiled: November 26, 2014Date of Patent: July 21, 2020Assignee: HOYA LENS THAILAND LTD.Inventors: Yoshitaka Matsui, Yoichi Ogo, Koushi Harada
