Abstract: The spectacle lens has at least a lens base material, and a multilayer film positioned on an eyeball-side surface of the lens base material, in which an average reflectance Rm (280-380) in a wavelength region of 280 to 380 nm, measured on the eyeball-side surface of the spectacle lens, is 10.0% or less, and a chroma C*, measured on the eyeball-side surface of the spectacle lens under a CIE standard illuminant D65, is 0.5 or more but 5.0 or less.

Abstract: Provided is a spectacle lens including multilayer films on both surfaces of a lens substrate, in which a sum of mean reflectances on both surfaces of the spectacle lens in a wavelength band of 360 to 400 nm is 6.0% or less, a sum of the mean reflectances on both surfaces of the spectacle lens in a wavelength band 400 to 440 nm is 20.0% or more, and a sum of the mean reflectances on both surfaces of the spectacle lens in a wavelength band 480 to 680 nm is 2.0% or less.

Abstract: Provided is a spectacle lens including multilayer films on both surfaces of a lens substrate, in which the sum of mean reflectances on both surfaces of the spectacle lens in a wavelength band of 400 to 440 nm is 20.0% or more, the reflectance on each surface of the spectacle lens has at least one maximum value in the wavelength band, and there is a difference between the mean reflectance on one surface of the spectacle lens and the mean reflectance on the other surface in the wavelength band.
