Abstract: A spectacle lens including a lens base material and a multilayer film provided on each surface of an eyeball-side surface and an object-side surface of the lens base material, in which a normal incidence mean reflectance Reye in a wavelength range of 430 to 450 nm measured on the eyeball-side surface of the spectacle lens and a normal incidence mean reflectance Robject in a wavelength range of 430 to 450 nm measured on the object-side surface of the spectacle lens each are more than 0%, and Reye is greater than Robject.

Abstract: Provided a spectacle lens including a lens base material and a multilayer film provided on each surface of an eyeball-side surface and an object-side surface of the lens base material, in which a mean reflectance RB(object) in a wavelength range of 430 to 450 nm measured on the object-side surface of the spectacle lens is equal to or more than 1.00%, and a mean reflectance RUV(eye) in a wavelength range of 280 to 380 nm measured on the eyeball-side surface of the spectacle lens is less than or equal to 15.00%.
