Abstract (en)
[origin: FR2921285A1] The method involves beveling an ophthalmic lens (100) to form a bevel on edge of the lens surrounded by a rear foot of the bevel, and blocking the ophthalmic lens beveled in a rotatably driving and blocking shaft (11) and a blocking nose (12) around a blocking axis (A1). The edge is retrieved from the ophthalmic lens blocked in the shaft and the nose. The edge retrieving process is carried by machining the rear foot, excluding the bevel, on a portion of surface of the foot using a grinding wheel (7) whose work generator is inclined with respect to the axis (A1). An independent claim is also included for a device for retrieving trimming of an ophthalmic lens.
