CPC G02C 7/024 (2013.01) [G02C 7/102 (2013.01); G02C 7/104 (2013.01); G02B 1/18 (2015.01)] | 7 Claims |
1. A spectacle lens comprising multilayer films on both surfaces of a lens substrate, wherein
a 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,
a reflectance on each surface of the spectacle lens has at least one maximum value in the wavelength band of 400 to 440 nm,
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 of 400 to 440 nm, and
the 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.
