ABSTRACT:
A temple construction arrangement for eyewear incorporating a retractable retaining strap in a hollow temple to form a part of and be attached to eyewear such as eye sight correction glasses, sunglasses, safety and protection goggles, and the like. The temple is separated or split lengthwise into two haves and a rotatable bearing, positioned transverse the length or longitudinal axis of the temple, is placed at the temple end attachable to the lens holding frame between the two halves. The retractable strap is disposed within and along the length of one side of the temple and, in combination with a longitudinal stretchable retracting member such as a spring or elastic cord, passes around the bearing. The attached retracting member is disposed along the length of the opposite side of the temple from that of the strap providing a retraction force for the retaining strap. The temple halves are then joined together to enclose the bearing, retaining strap, and retracting member as a finished unit.
