ABSTRACT:
Disclosed is an improved eyeglass frame having two upper half-rims of arc-shaped metal wires and two lower half-rims of high-tension strings to encircle and hold associated lenses. Each arc-shaped metal wire has hooks formed on its opposite ends, and each high-tension string has loops formed on its opposite ends to be caught by the hooks of the arc-shaped metal wire. The arc-shaped metal wire is relatively thick, and it is partly exposed from the circumferential groove of the lens, thereby permitting the bridge and temple to be soldered directly to the exposed portions of the metal wire. This arrangement has the effects of significant reduction of manufacturing cost and giving a neat appearance to the frame.
