Abstract
A pair of foldable spectacles has a two-lens front piece (30) to which two side pieces (20a, 20b) are pivotally connected by means of resilient corner hinges (25). The front piece (30) has a central hinge assembly (40) by means of which the front piece can be folded to a position where its lenses (31, 32) are held between and protected by the side pieces (20a, 20b). Each side piece (20a, 20b) has a first portion (21) which is connected to the front lens piece (30) by a resilient corner hinge (25), a second portion (22) which forms a free end portion of the side piece, and a resilient transition portion (23) between the first and second portions (21, 22). Thanks to the resilient corner hinges (25) and the resilient transition portion (23) of the two side pieces (20a, 20b), the spectacles (10) in use are held in place in a reliable manner since the side pieces (20a, 20b) are pressed against the side of the user's head.
