A spectacle lens including a lens base material and a multilayer film provided on each surface of an eyeball-side surface and an object-side surface of the lens base material, in which a normal incidence mean reflectance Rin a wavelength range of 430 to 450 nm measured on the eyeball-side surface of the spectacle lens and a normal incidence mean reflectance Rin a wavelength range of 430 to 450 nm measured on the object-side surface of the spectacle lens each are more than 0%, and Ris greater than R.

Spectacle lens and spectacles

Provided a spectacle lens including a lens base material and a multilayer film provided on each surface of an eyeball-side surface and an object-side surface of the lens base material, in which a mean reflectance Rin a wavelength range of 430 to 450 nm measured on the object-side surface of the spectacle lens is equal to or more than 1.00%, and a mean reflectance Rin a wavelength range of 280 to 380 nm measured on the eyeball-side surface of the spectacle lens is less than or equal to 15.00%.

Spectacle lens that reflects blue light, and spectacles equipped with the spectacle lens

Provided are a spectacle lens having a tin oxide layer on a lens base material, wherein the tin oxide layer has a composition gradient in which an oxygen content rate as anatomic percentage increases from the lens base material side to the other side, and spectacles provided with the spectacle lens.
