The method involves fixing a lens in a position where a reference point of the lens corresponds to a punch (33), by moving the lens in a plane perpendicular to an axis of a piercing tool (15). The tool is brought closer to the lens. The punch is retracted to disengage a support zone of the lens. The tool is controlled by a numerically controlled piercing machine (12) to pierce the lens, by using the reference point as zero point. - An INDEPENDENT CLAIM is also included for a device for implementing a method of piercing the ophthalmic lens. |
