The pair of spectacles, especially sunglasses, consists of a main outer frame (1) with side-pieces (3) and lenses, and an inner frame (5) with no side-pieces, carrying preferably correcting lenses and attached to the outer frame by a nose-piece (8) replacing one on the outer frame. The two nose-pieces, equipped with pads to support the spectacles on the wearer's nose, are interchangeable and clip into a bridge on the main outer frame.
