The spectacles have left (2) and right (4) full edges for accommodation of lenses and a bridge (6) which connects the full edges. Two cheeks (8,10) are fitted to the edges of the full edges turned away from the bridge. The two full edges, the bridge and the two cheeks are formed with one another in one piece and are made of plastics. The two full edges are flexible and formed by a closed elastic band. On their inner sides is an all-round projection for engagement with an all-round groove at the edge of the lens. The projection has a semicircular profile. The two full edges can have a circular or rectangular profile. |
