A grip-on eyeglass device is designed for mounting auxiliary eyeglasses onto primary spectacle frame by using a single plastic grip. The plastic grip, constructed at the nasal area on the rear side of the auxiliary eyeglasses, is designed to plug with its corresponding socket located behind the bridge of the primary spectacle frame or to plug directly with the built-in recesses formed on top and bottom sides of the bridge of another primary spectacle frame, bringing the auxiliary eyeglasses into attachment with two options of primary spectacle frames. The assembly is perfect because the two legs of the grip are made with bulging heads while its corresponding socket is made recessed, making clamping action effective when they come into attachment. The attaching process is easy, yet the bond is so strong that it avoids any possible detachment or downward movement of the auxiliary eyeglasses from the primary spectacle frame. Elimination of using extra metal attaching accessories keeps the eyeglasses light and its appearance neat.
