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 is a spectacle lens including a lens substrate, a multilayer film located on an object-side surface of the lens substrate, and a multilayer film located on an eyeball-side surface of the lens substrate, wherein a blue light absorption rate is 10.0% or higher, the lens substrate includes a blue-light-absorbing compound, and an average reflectance in a wavelength range of 400 nm to 500 nm measured on each of the object-side surface and the eyeball-side surface of the spectacle lens is in a range of 10.0% to 20.0%, and a luminous reflectance measured on each of the object-side surface and the eyeball-side surface of the spectacle lens is less than 2.0%.
