Holding means are provided on the auxiliary frame (9) in order to restrain the auxiliary frame removably on the main frame with consequent superposition of the lenses of the frames. The holding means comprise at least one clamp element (13) which is fixedly joined to the auxiliary frame (9) and which includes a pair of jaws (14, 15) capable of being clamped on the main frame (2), means for magnetic connection (16, 17) being provided between the jaws (14, 15) in order to exert the clamping load of the clamp (13) on the main frame (2) and the consequent holding of the auxiliary lenses (10a, 10b) on the spectacles.</p> |
