Zusammenfassung:	Method for determining a surface of a face of an optical lens to be mounted to a spectacle frame, the method comprising:- a contour data providing step (S1), during which contour data representing a contour of the spectacle frame is provided,- a target curvature data providing step (S2) during which target curvature data representing the target curvature of the surface to be determined over an evaluation zone of said surface is provided,- an optical surface determining step (S3), during which a surface is determined so as to minimize:o the difference between the target curvature and average curvature of the surface over the evaluation zone, ando the difference between the contour of the spectacle frame and the periphery contour of the surface, the periphery contour of the surface corresponding to the contour of the surface to be determined of the optical lens after the optical lens has been edged to be mounted in the spectacle frame.
