The invention relates to a system for perforating lenses for rimless spectacle frames, characterised in that said system has a template made of resilient, flexible material, having an undersized cavity in the shape of the lens, having a depth which is smaller than the thickness of the template, in which the lens is inserted and immobilised by the resilience of the material when inserted tightly, provided with a circular cavity which passes through the template, located in the centre of the cavity in the shape of the lens and having a diameter which is smaller than the width of said cavity, in order correctly to secure the lens in the position perpendicular to the plane for attachment of the edge of the circumference thereof, and provided with a guide and a mark located respectively on the main plane and the plane perpendicular to the main plane of the template, which interact, respectively, with a guide and a marked line belonging to the perforation base and which enables the location of the perforation to be accurately determined. |
