A description is given of spectacles with interchangeable lenses comprising a front mount (2) defining seats (3) for respective lenses (4), the seats comprising at least one portion configured as a groove (7) capable of receiving at least partially a peripheral edge (4a) of the corresponding lens (4), means for locking each lens on the mount being provided at the respective groove and acting between the groove and the corresponding lens edge, for locking and retaining the lens (4) in position on the front mount (2), wherein the locking means act exclusively by means of magnetic attraction between parts associated respectively with the lens (4) and the corresponding groove (7) of the mount (2). The locking means comprise, for each lens, at least one first magnet element (8) or element made of ferromagnetic material provided on the lens edge (4), capable of co-operating, by magnetic attraction, with at least one corresponding second element (9) of ferromagnetic material or magnet element provided within the groove (7) in a corresponding position, such as to ensure the retention of the lens (4) in position on the front mount (2), as a result of the insertion of the lens (4) into the groove. |
