ABSTRACT:
The central piece of a full-rim eyeglass frame includes a left full rim (2) for receiving a left lens, a right full rim (4) for receiving a right lens, a bridge (6) joining the two full rims, and two endpieces (8, 10). The two full rims, the bridge and the two endpieces are integrally formed as a single piece, from a plastic. The two full rims (2, 4) are flexible, and are constituted by a closed, elastic band. The central piece of the full-rim frame is assembled into a central piece of a pair of eyeglasses with two lenses, whose outer circumferential lines have somewhat larger dimensions than the inner contour lines of the two full rims, so that the full rims of the central piece of the eyeglasses are stretched around the lenses, and their shape conforms to the shape of the lenses.
