Method for fitting spectacle lenses into full rim spectacle frames

Method for fitting spectacle lenses into full rim spectacle frames, comprising machining the edge of the spectacle lenses to be fitted,

• comprising the method steps of:
• working a circumferential, step-like chamfer with a curvature determined as a section of a sphere surface with a defined radius r into the holders for the spectacle lenses in the full rim spectacle frame on the front side or back side,
• machining the edge of the spectacle lenses to be inserted, in the form of a front-side or back-side circumferential step-like bevel with a curvature determined according to the sphere surface with a defined radius r of the chamfer, which consequently represents an exact negative image of the step-like chamfer worked into the spectacle frame,
• fitting the spectacle lenses into the holders in the full rim spectacle frames on the front or back side, with precise engagement of the bevel into the chamfer of the spectacle frame, and
• adhesively bonding and/or welding the inserted spectacle lenses to the holders in the full rim spectacle frame.
