Method for manufacturing frameless glasses

The manufacturing of rimless spectacles comprises manufacturing (S1) two lens blanks of a plastic material, applying a coating to the front side and the rear side of the lens blanks, machining the lens blanks in such way that the two lenses having a desired lens shape are obtained, manufacturing the two lugs, manufacturing the bridge, determining the mounting positions for the fasteners of the lugs and the bridge on the front side/the rear side of the lenses, and removing the coating at the mounting positions to form joining surfaces at the lenses.

The rimless spectacles comprise two lenses, a bridge disposed between the two lenses for connecting the two lenses to each other, two lugs each of which is connected to one of the two lenses at an edge area of the lens facing away from the bridge, and two sides each of which is hingedly connected to one of the two lugs in which each lug includes a fastener having a joining surface for connecting the lug to either of the two lenses. The bridge includes two fasteners having a joining surface for connecting the bridge to the two lenses. The applied coating comprises a hard layer, a dirt-repelling layer, an anti-reflection layer or a reflective layer. The coating is removed up to the entire thickness of the coating, at the mounting positions. For forming the joining surfaces at the lenses, the coating is removed at the mounting positions in an area of the front side and/or the rear side of the respective lens, which corresponds to shape and dimensions to the joining surface of the respective fastener to be adhesively bonded. The coating is removed by grinding or milling and using a face grinding tool, which performs a high-frequency rotation or reciprocating movement. The coating is removed by abrasive-blasting abrasive particles. The
