<p>Enhanced eyeglasses of the type comprising a frame (2) provided with lenses (7) and at least a frame element (3, 4, 15), whereto is removably connected an elastically extensible wire (5) which is engaged in corresponding holes (6) of the frame element (3, 4, 15) and which is tensioned in such a way as to make the frame (2) and the lenses (7) mutually integral. The holes (6) include at least a channel (8, 9) having different passage sections between inlet and outlet. The wire (5) is provided with transversely prominent and consecutive projections (10), whose transverse dimension is lesser than the inlet passage section of the channel (8, 9) and greater than the outlet passage section of the channel (8, 9). The wire (5) is provided with end segments (5a, 5b) able to engage in succession on a pair of holes (6) after their preliminary insertion and a subsequent translation in the respective channel (8, 9), whereupon the wire (5) is secured by elastic interference of the projections (10) with the passage sections of the channel (8, 9).</p> |
