Abstract: 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.

Abstract: Interchangeable tethered glasses for adjustably positioning relative to a face of an individual for filtering light into eyes of the individual. The inventive device includes a frame assembly for supporting a pair of lenses over eyes of an individual. An ear engaging assembly extends from opposed sides of the frame assembly for engaging ears of the individual to secure the frame assembly relative thereto. The ear engaging assembly includes a tether extendable over the ears of the individual, and a weight coupled to a distal end of the tether for maintaining a desired tension within the tether.
