Claim 0:
1. A spectacle lens comprising at least a lens base material, and a multilayer film positioned on an eyeball-side surface of the lens base material,
wherein an average reflectance Rm (280-380) in a wavelength region of 280 to 380 nm, measured on the eyeball-side surface of the spectacle lens, is 10.0% or less,
a chroma C*, measured on the eyeball-side surface of the spectacle lens under a CIE standard illuminant D65, is 0.5 or more but 5.0 or less,
a maximum reflectance Rmax (450-700) in a wavelength region of 450 to 700 nm, measured on the eyeball-side surface of the spectacle lens, is 3.0% or less,
a minimum reflectance Rmin (450-700) in a wavelength region of 450 to 700 nm, measured on the eyeball-side surface of the spectacle lens, is 0.5% or more, and
the spectacle lens has a hue angle h, measured on the eyeball-side surface of the spectacle lens under a CIE standard illuminant D65, of 180.0 degrees or more but 300.0 degrees or less.
