Abstract: The invention relates to a system for fastening the bridge (30) or the hinge elements (10, 20) connecting the temples (A) to the lenses (L) of eyeglasses, where the ends of the bridge (30), as well as each of the ends (12, 22) of the temple connecting hinge elements (10, 20) which is directed towards the respective lens is furnished with a respective fork-shaped structure, with at least one pair of prongs (33-34, 36-37, 13-14, 23-24) lying in the plane at right angles to the plane of the lenses and where each lens is provided with holes (61-62, 63-64) located at the points of connection with the ends of the bridge (30) and/or of the temple connecting hinge elements (10, 20). The holes are equal in number to the number of prongs on the respective fork-shaped structures and comprise, inside them, respective tubular sleeves (53, 54).

Abstract: Eyeglasses with lenses of the type which are free of mounting, called “extralight” in which the lenses (1) are connected directly to the central bridge and to the extremity of the two lateral risers by means of a threaded attack, wherein the extremities of the risers (2) and extremities of the central bridge (3) have a terminal portion (4) which is inserted from the internal surface of the lens within corresponding niches (5) formed on the internal surface of the lenses and which is threadedly engaged by an element passing through the lenses from the external surfaces.
