Abstract
A method for providing spectacle lenses that have a microstructure on at least one side. A procedure is described, in which the structure is introduced into a face of the lens after the processing of the face of the lens. Processing steps used to achieve the optical quality of the corresponding surface can be omitted. The back face of a spectacle lens may be microstructured by CNC-controlled turning after a first shaping processing, wherein the polishing step is omitted.
