METHOD FOR CUTTING-OUT A MULTI-LAYER OPHTHALMIC LENS

摘要

The invention relates to a method for cutting-out a multi-layer ophthalmic lens (100) following a desired contour (C3), including: a step of pre-blanking the ophthalmic lens (100) using a preliminary tool (210; 223), according to a preliminary contour (Cl,Cl'); a step of blanking said 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 (Cl, Cl') 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 said ophthalmic lens (100) so as to apply a radial force of between 0.1 and 5 N to the ophthalmic lens (100) during said blanking step.
