the temples are formed as one piece with a top frame piece, and

the top frame piece has provided on it fastening means for the lens,

wherein said fastening means for the lens ( 2 ) are injunction-molded from plastic in one piece with an intrinsically elastic tip frame piece ( 3 );

wherein the fastening means comprise at least two hook-like projections ( 11 ) on the top frame piece that hook over the edge of the eyeglasses, and, formed on a downwardly projecting vertical extension ( 17 ) of the top frame piece in the nose region, a hook projection ( 19 ) that can be snapped into place in a nose recess ( 14 ) of the lens ( 2 );

wherein the top frame, the vertical extension and the hook projection are of one-piece.

2. Eyeglasses according to claim 1 , wherein, when not worn, the templates ( 4 , 5 ) extend inward from the top frame piece ( 3 ) in an arc shape.

3. Eyeglasses according to claim 1 , wherein the lens has at its upper edge U-shaped recesses ( 15 ) that are dimensioned such that they hook in a form-fitting manner over the protrusions ( 12 ) of the hook-like projections that extend away from the top frame piece ( 3 ), the lateral edge of the recesses, in turn, having a transversely extending section ( 13 ) on the front end of the protrusions ( 12 ) hooking over it.

4. Eyeglasses according to claim 1 , wherein in the region of the lateral outer edge of the lens ( 2 ), the top frame piece ( 3 ) has provided on it projections ( 8 ) that hook over the lateral upper edge of the lens ( 2 ) in its inserted state.
