An eyeglass device comprised of a primary eyeglass frame (20) and an auxiliary eyeglass frame (10), each containing lenses therein. The primary eyeglass frame (20) includes a bridge (25) and earpieces, which are connected to extensions (21) on each side of the frame. The bridge may be made of a flexible memory alloy such as NiTi or CuAlBe. The extensions (21) have magnets mounted on the undersides of them. The auxiliary eyeglass frame (10) also includes a bridge (13) and temporal extensions (11). These extensions of the auxiliary eyeglass frame have magnets mounted to the tops of them. The magnets engage magnetically with each other to connect the auxiliary eyeglass frame to the primary eyeglass frame. The flexible bridges of the primary and auxiliary eyeglass frames assist in preventing the auxiliary eyeglass frame in case it jostled by the wearer because they can withstand slight distortion.

La présente invention concerne un dispositif pour verres de lunettes qui comprend une monture (20) pour verres de lunettes principale et une monture(10) pour verres de lunettes auxiliaire, chacune contenant des lentilles. La monture (20) principale comprend un pont (25) et des branches connectées à des extensions (21) situées de chaque côté de la monture. Le pont peut être fabriqué dans un alliage souple à mémoire de forme tel que NiTi ou CuAlBe. Les extensions (21) possèdent des aimants montés sur leur face inférieure. La monture auxiliaire (10) comprend également un pont (13) et des extensions (11) temporales. Ces extensions de la monture auxiliaire possèdent des aimants montés sur leur partie supérieure. Ces aimants entrent en contact magnétique entre eux de façon à connecter la monture auxiliaire à la monture principale. Les ponts souples des montures principale et auxiliaire permettent d'éviter que la monture auxiliaire se désolidarise de la monture principale en cas de mouvements incontrôlés du porteur de ces montures, car ces ponts peuvent supporter une légère déformation.
