The folding spectacles exhibit a front frame (1) composed of two lens frames (2) reciprocally hinged, and two earpieces (5), each of which is hinged to one of the lens frames (2). The earpieces (5) each comprise a plurality of moving segments (7) telescopically and slidably coupled one to a next such that each of the earpieces (5) can assume a series of configurations comprised between a maximum extension and a minimum extension thereof; in the minimum extension configuration the earpieces (5) can be housed compactly between the lens frames (2) when folded one on another. |
