Summary:An aspect of the present invention relates to 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 R eye 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 R object 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 R eye is greater than R object .
