Abstract:
An optical lens blank includes a first and a second lens surface, which are arranged opposite each other and which are delimited at a lens circumference, wherein the first lens surface has a surface geometry that corresponds to a first partial cutout from a first melon shape. A range of blanks consisting of such lens blanks have first lens surfaces of varying degrees of curvature, wherein the different degrees of curvature are based on different melon shapes. Finally, a method for producing a spectacle lens from such an optical lens blank includes mechanically shaping at least the first or second surface, and separating a cutout from the mechanically shaped lens blank.
