ABSTRACT:
A method and apparatus for mounting auxiliary eyeglasses on conventional eyeglasses in which magnets are attached to appendages on the auxiliary eyeglasses mating with magnets mounted on the temple extensions of conventional eyeglasses. The magnets on the auxiliary eyeglasses are mounted in sockets formed on the appendages of the auxiliary eyeglasses such that their maximum magnetic force is oriented vertically or parallel to the plane of the conventional eyeglass frame. The appendages on the auxiliary eyeglass frame fit beneath the temple extensions on the conventional eyeglasses frame to hold the auxiliary frames in place solely by the magnetic attractive force. The orientation of the magnets is such that the maximum magnetic force resists any downward movement of the auxiliary eyeglasses on the conventional eyeglasses when installed. In a modification of the embodiment, a clip is attached to or formed on the bridge of the auxiliary eyeglasses for fitting over the bridge of the conventional eyeglasses. In yet another embodiment, clips are formed on the frame of the auxiliary lens to fit over the frame of the conventional eyeglasses. Magnets are embedded in the bridge of the auxiliary eyeglasses that mate with complementary magnets in the bridge of the conventional eyeglasses when the bridge is slid beneath the bridge of the conventional eyeglasses.
