This invention is a completely mechanical method of constructing eyewear, without brazing. An eyewear frame is formed by a continuous, bent, spring wire. Sidepiece 47 is fixedly attached to frame endpiece parts 30 and 31 by mating a bent portion of each within compression spring 40. The Vertically tall, transversely thin sidepieces can support with scant lateral pressure to a wearer's head, and can close can close against the frame without hinges. The length of a spring over the endpiece confines lense 56 in upper and lower portions of a frame's eyewire. Lense 55 has been removed by laterally compressing spring 40 around the folded-over endpiece parts and letting the ends of the endpiece parts spread vertically apart. Elongated members, unrelated to eyewear endpieces and sidepieces, can be fixedly attached and removed, and/or spread in the ways described above. A nosebridge can be formed by a continuous, bent, spring wire. It's transversely elongated bridgeportion 20 adds strength and stability to the frame. Hook 22 at an upper lateral end of the bridgeportion plus a bridgeportion frontward bow substantially mechanically encircle the frame's bridge in the latitudinal/longitudinal plane. The hooks and bow hold together upper and lower medial portions of a frame's eyewire. The vertical stability of the lenses, supported in the frame's eyewires, keeps the nosebridge from rotating. Nosebridge hook 22 continues downwardly/rearwardly as nosepad arm 60. The lateral angling of the arms also keeps the nosebridge from rotating. Each wire end of the arms upwardly loop; each loop can secure a nosepad balljoint.

A golf club is fabricated with at least one vertical stability plate and/or at least one horizontal stability plate at a club head. The golf club is provided with a stability plate and an asymmetrical wing, or a combination of the same, which are installed at an upper side or left and right sides of the head of the golf club such as a driver, wood or iron, for example.
