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.
