Abstract

A spectacle lens with an object-sided front face and an eye-sided rear face, wherein at last the rear face comprises a viewing region that contributes to the optical effect of the spectacle lens and a carrier rim region that at least partially surrounds the viewing region and that does not significantly contribute to the optical effect of the spectacle lens. The rear face of the spectacle lens in the carrier rim zone is constructed substantially from a cosmetic viewpoint without consideration of the optical image-forming properties. A method for producing this spectacle lens is also provided.
