PROBLEM TO BE SOLVED: To provide a spectacle lens having coats (reflection coating) having property for reflecting light in a predetermined wavelength range on both surface thereof and achieving preferable wearing feeling.SOLUTION: The spectacle lens comprises coats exhibiting property for reflecting light in a predetermined wavelength range on both surfaces of a lens substrate, namely an object side surface and an eyeball side surface of the lens substrate. The coats on one or both surfaces have reflectance gradient in which reflectance to the light reduces continuously or gradually from a lower position to an upper position when a user wears the spectacle, or from the upper position to the lower position when a user wears the spectacle. |
