    Abstract: During the chamfering of the edge (6) of the lens, the edge is scanned by a plane light beam (23) which forms a linear light mark (24). An image of the light mark is formed in an optical reception system (26). This image is used to monitor and control the machining process. The procedure provides chamfering for the edge (6) of a an ophthalmic lens (1), during which the edges of the lens are removed successively in order to define the chamfered edge (6). During this process, the edge (6) of the lens is scanned by a plane light beam (23) which forms a linear light mark (24). At the same time an image of the light mark is formed in an optical reception system (26). From this it is possible to deduce the successive positions of the image, and hence the position of the chamfer formed on the edge of the lens. The process is carried out whilst the lens is mounted to rotate about an axis (A1), whilst its edge is in contact with the chamfering tool. The relative position of the lens and the tool are adjusted as a function of the light mark detection.

    Abstract: The opthalmic lens moulding process has a lens section (4) with a forward face (2) and a rear face. In the lens lifting step the lit face of the lens is swept by a luminous beam (22) whilst simultaneously raising on the optical receiver (24) the successive image points following the task settings (23) thus finding the lifting effect on the three dimensional edges.
