摘要

Device for fixing a structural part (1) to a spectacle lens (2) comprises an end bridge (8) of the structural part which overlaps the edge of the lens, two parallel fixing pins (4) protruding from the end bridge, and plastic shells (6) which form a head and inserted in holes of the lens. The end bridge consists of fixing pins made from a plastic. The plastic shells are joined via a common stop head (7). The elastic modulus of the plastic of the fixing pins correspond to three times the elastic modulus of the plastic of the plastic shells. Preferred Features: The two plastic shells are made of a crystalline plastic and the fixing pins are made of an amorphous plastic.
