ABSTRACT:
A spectacle frame comprising a pair of lens frames, a pair of temples hingedly connected to the outer portions of the respective lens frames, bridges each projecting from the inner portion of one of the lens frames toward the other lens frame, and a hinge portion provided at the forward ends of the bridges to make the lens frames inwardly foldable. The hinge portion has a pivot pin inclined at a small angle with a vertical line, so that when the spectacle frame is folded, the inner faces of the lens frames are opposed to each other with the temples opposed to the outer faces of the lens frames.
