Disclosed is a semi-finished lens that includes a blank formed in a first material having a first hardness, the blank having an outline, a first face and a second face configured to be surfaced so as to constitute a first optical face of the ophthalmic lens, and a top layer formed in a second material having a second hardness greater than the first hardness, the top layer having an outline, a first face and a second face, the second face of the top layer being arranged on the first face of the blank. The outline of the top layer is equal to or included in the outline of the blank, and satisfies to a predetermined dimensional selection criterion involving the final outline of the ophthalmic lens.

An apparatus and a method for trimming a module are disclosed. In and embodiment the method includes fixing a rear transverse side of module, guiding the rear cutting head along the rear transverse side thereby cutting off a rear overlapping portion of the overlapping film and releasing the rear transverse. The method further includes moving the module into a region of two longitudinal cutting devices, fixing the module on both longitudinal sides, guiding longitudinal cutting heads along the longitudinal sides thereby cutting off longitudinally overlapping film portions on both longitudinal sides, and releasing the longitudinal sides of the module. The method furthermore includes moving the module into a region of the front cutting device, fixing a front transverse side of the module, guiding a front cutting head along the front transverse side thereby cutting off a front overlapping portion of the overlapping film.
