Abstract
A spring-action temple for eyewear includes an L-shaped notch formed in the outwardly facing surface of the temple, the notch forming a finger portion having a tip portion. As a lateral force is applied to the back end of the temple, the temple flexes at a thinned wall section of the notch for a first distance of travel T.sub.1, with the tip portion moving toward the front end of the temple until the tip abuts the wall of the notch. The temple may flex even further outwardly by flexing at a location rearwardly of the notch for a second distance of travel T.sub.2. Upon removal of lateral forces, the temple automatically returns to its unbiased position.
