摘要 [Object] Excellent external appearance such that the color is not changed by reflection is provided. [Means to solve the problems] A spectacle lens 1 is provided with a lens base material 2 and an antireflection film 5 provided on the lens base material 2 (an inner surface 3 and an outer surface 4 seen from a spectacle wearing person). The lens base material 2 colored with a dye. The antireflection film (antireflection coating layer) 5 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 2 and transmits all of the remainder. The same color as referred to herein means that the chromaticity coordinate values are equal to each other.
