Abstract
A compression joint for assembly at the junction of an eyeglass temple and the adjacent lens frame. The joint has a resiliently compressible portion that is placed under compression when a temple is in fully open position. This permits the temple to swing beyond a normal open position and to be biassed toward a partially open position, thereby providing snug fitting glasses regardless of head size and/or wear during use.
