Abstract
Herein disclosed is a multiple part eyeglass frame for rimless eyeglasses manufactured from plastic having properties which withstand the constant flexing associated with eyeglasses. The present invention is especially useful in situations where a conventional temple hinge is not used. The frame is highly effective for absorbing stresses on eyeglass lenses at attachment points of the temple members. Temples of the present invention are formed of two individual pieces allowing a temple length to be adjusted. The temple pieces are fabricated, such that when joined, the resulting temple follows the normal curvature of a wearer's head. The present invention incorporates a plastic nose bridge with one or more posts as attachment means for a replaceable nose pad bridge unit. Additionally, means for adjusting the length of the temple members is provided.
