METHOD FOR CUTTING-OUT A MULTI-LAYER OPHTHALMIC LENS

摘要

A method for cutting-out a multi-layer ophthalmic lens (100) following a desired contour (C3), includes: a step of pre-blanking the ophthalmic lens (100) using a preliminary tool (210; 223), according to a preliminary contour (C1, C1′); a step of blanking the ophthalmic lens (100) using a blanking wheel (210), following a blanking contour (C2, C3); and a step of finishing the ophthalmic lens (100) using a finishing tool (212). According to the invention, the preliminary contour (C1, C1′) is larger than the desired contour (C3), and the blanking wheel (210) used has a granulometry of between 0.1 and 0.5 mm and is controlled in relation to the ophthalmic lens (100) so as to apply a radial force of between 0.1 and 5 N to the ophthalmic lens (100) during the blanking step.
