Abstract: A spectacles set includes a primary spectacle frame which includes two nose supports thereof and a detachable shelter frame adapted for mounting in front of the primary spectacle frame. The detachable shelter frame includes a shelter frame for supporting two auxiliary lenses and a pair of magnetic attachment arrangements connected to the shelter frame. Each of the magnetic attachment arrangements includes a supporting arm extending rearwardly from the shelter bridge to securely mount the shelter frame in front of the primary spectacle frame and a magnetic seat which is connected to the supporting arm and extended to magnetically attach the nose supports of the primary spectacle frame so as to hold the shelter frame on the primary spectacle frame in position.

Abstract: A new method of producing central bridge and support arms for spectacles where no welding is required, and no screws were needed to secure lenses to frame. Protruding members on end portion of central bridge are formed, together with the bridge itself, when cut out by a wire-cutting means. Fitting lenses to spectacle frame requires pressing capping pieces into the protruding members having ratchet-like teeth to receive and secure the lenses in place. Durability of spectacle frames is enhanced as a result of no temperature change to the elasticity of the frame material.
