ABSTRACT:
A pair of auxiliary glasses with magnets in the present invention are provided with an upper and a lower against flanges which are backwardly protrudent on the bridge. Two magnets are respectively inserted in the upper and the lower against flanges, which are corresponding to each other. A pair of primary eyeglasses are provided with a magnet inserted in a proper position of the bridge. The bridge of the primary eyeglasses is capable of being inserted into the space between the upper and the lower against flanges of the bridge of the auxiliary glasses. Therefore, the auxiliary glasses can firmly attach to the primary eyeglasses not only by the function of the upper and the lower against flanges firmly clipping the bridge of the primary eyeglasses but also by the magnetic forces of the magnets.
