Abstract:
A method for manufacturing a spectacle lens includes the steps of providing an integral main lens. The integral main lens has a front surface and a back surface and is at least one selected from a group consisting of a spherical power lens, an astigmatic power lens, and a lens having a main curvature of the front surface in a first meridian and a main curvature of the back surface in the first meridian which are different so as to provide for a spherical power different from zero; and applying at least one additional lens element to at least a part of the front surface and/or at least a part of the back surface, wherein the at least one additional lens element includes at least one layer having a multitude of layer elements, in particular printed layer elements. Further, the invention is directed to a corresponding spectacle lens.
