Abstract
Official abstract text for this publication.
An aspect of the present invention relates to a spectacle lens including coating films, having a characteristic of reflecting light in a specific wavelength region, on both of an object-side surface and an eyeball-side surface of a lens base material, where one or both of the films on the surfaces have a reflectance gradient where a reflectance of the light decreases successively or gradually from a portion positioned downward to a portion positioned upward during use or from the portion positioned upward to the portion positioned downward during use.
First claim
Opening claim text (preview).
1 . A spectacle lens, comprising: a lens base material; and coating films, having a characteristic of reflecting light in a specific wavelength region, on both of an object-side surface and an eyeball-side surface of the lens base material, wherein one or both of the coating films on the surfaces have a reflectance gradient where a reflectance of the light decreases successively or gradually from a portion positioned downward to a portion positioned upward during use or from the portion positioned upward to the portion positioned downward during use. 2 . The spectacle lens according to claim 1 , wherein the lens base material is a minus lens where a thickness in a center part is thinner than a thickness in a peripheral part, and the coating film, having a reflectance gradient where a reflectance of the light decreases successively or gradually from the portion positioned downward to the portion positioned upward during use, is provided on the object-side surface. 3 . The spectacle lens according to claim 1 , wherein the lens base material is a minus lens where a thickness in a center part is thinner than a thickness in a peripheral part, the coating film, having a reflectance gradient where a reflectance of the light decreases successively or gradually from the portion positioned downward to the portion positioned upward during use or from the portion positioned upward to the portion positioned downward during use, is provided on the eyeball-side surface, and the coating film without a reflectance gradient is provided on the object-side surface. 4 . The spectacle lens according to claim 3 , wherein the coating film on the eyeball-side surface has a higher or lower normal incidence average reflectance in the specific wavelength region in a lower region positioned downward from a fitting point or an optical center during use than a normal incidence average reflectance in the specific wavelength region in an upper region positioned upward from the lower region, and the normal incidence average reflectance in the specific wavelength region of the coating film on the object-side surface is lower than or equal to the normal incidence average reflectance in a region having a low normal incidence average reflectance in the upper region or lower region of the coating film on the eyeball-side surface. 5 . The spectacle lens according to claim 1 , wherein the lens base material is a plus lens where a thickness in a center part is thicker than a thickness in a peripheral part, and the coating film, having a reflectance gradient where a reflectance of the light decreases successively or gradually from the portion positioned downward to the portion positioned upward during use, is provided on the eyeball-side surface. 6 . The spectacle lens according to claim 1 , wherein the lens base material is a plus lens where a thickness in a center part is thicker than a thickness in a peripheral part, the coating film, having a reflectance gradient where a reflectance of the light decreases successively or gradually from the portion positioned downward to the portion positioned upward during use or from the portion positioned upward to the portion positioned downward during use, is provided on the object-side surface, and the coating film without a reflectance gradient is provided on the eyeball-side surface. 7 . The spectacle lens according to claim 6 , wherein the coating film on the object-side surface has a higher or lower normal incidence average reflectance in the specific wavelength region in a lower region positioned downward from a fitting point or an optical center during use than a normal incidence average reflectance in the specific wavelength region in an upper region positioned upward from the lower region, and the normal incidence average reflectance in the specific wavelength region of the coating film on the eyeball-side surface is lower than or equal to the normal incidence average reflectance in a region having a low normal incidence average reflectance in the upper region or lower region of the coating film on the object-side surface.
