Zusammenfassung: | The present invention provides a spectacle lens having a lens base material containing a blue light absorbing compound and a multilayer film containing a metal layer having a film thickness of 1.0-10.0 nm, the spectacle lens having a blue light blocking rate of 21.0% or more, an average reflectance of 1.00% or less in a 400-500 nm wavelength region as measured on an object-side surface, and an average reflectance of 1.00% or less as measured on the object-side surface. And the average reflectance in the 400-500 nm wavelength region measured on the eyeball-side surface is 1.00% or less.
