PROBLEM TO BE SOLVED: To provide an optical product and spectacle lens, excellent in visibility while cutting both of blue light and ultraviolet light.SOLUTION: The optical product (a spectacle lens) includes a base and an optical multilayer film formed on the surface of the base. The optical multilayer film has six or more layers having a low refractive index layer and high refractive index layer alternately arranged. When a layer closest to the base is used as a first layer, and the final layer is a low refractive index layer, the optical film thickness M of the final layer and the total M+N of the optical film thickness M and the optical film thickness N of the layer adjacent to the final layer satisfy both conditions of [1]0.295λ≤M≤0.415λ and [2] 0.460λ≤M+N≤0.560λ when a design wavelength λ is 500 nm. |
