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 method implemented by a computer for determining surfacing data to obtain a surface of a lens element, the surface of the lens element including: a refraction area having a first curvature; and multiple optical elements placed on at least part of the finished optical surface, each optical element having at least a second curvature.
