发明名称 Spectacle lens and spectacle
摘要 A spectacle lens is provided with a lens base material and an antireflection film provided on the lens base material (an inner surface and an outer surface seen from a spectacle wearing person). The lens base material is colored with a dye. The antireflection film (antireflection coating layer) is formed by a vapor deposition method such that it slightly reflects incident light in the same color as that presented by the lens base material and transmits all of the remainder. The same color as referred to herein means that the chromaticity coordinate values are equal to each other.
