ABSTRACT:
An eyeglass device comprised of a primary eyeglass frame and an auxiliary eyeglass frame, each containing lenses therein. The primary eyeglass frame includes a bridge and earpieces, which are connected to extensions on each side of the frame. The bridge may made of a flexible memory alloy, such as NiTi or CuAlBe. The extensions have magnets mounted on the undersides of them. The auxiliary eyeglass frame also includes a bridge and temporal extensions. These extensions 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 from becoming dislodged from the primary eyeglass frame in case it jostled by the wearer because they can withstand slight distortion.
