Abstract: A surfacing tool for optical purposes, includes a body (30) for mounting the tool (10) on a surfacing machine, an elastically compressible interface (12), a flexible buff (13), and a connecting structure between the mounting body (30) and the elastically compressible interface (12). The connecting structure includes a bell (11), and a supporting body (14) between the peripheral wall (17) of the bell (11) and the periphery of the interface (12), the body (30) for mounting the tool (10) on a surfacing machine (32, 33) being connected to the main body (16) on the side opposite the side facing the interface.

Abstract: 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.

Abstract: The tool includes a base including a rigid carrier and a flexible collar encircling the rigid carrier; an elastically compressible interface; and a flexible buffer including a central portion that is located in line with the rigid carrier and a peripheral portion that is located transversely therebeyond. This peripheral portion is connected to the carrier exclusively via the interface and via the collar, wherein the collar is configured so that the tool is elastically deformable between a rest position that it adopts in the absence of stress and a reference position in which the transverse end second surface of the flexible buffer is pressed against a reference surface that is spherical and of radius included between 40 mm and 1500 mm.
