More Information
Summary: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.
