Abstract
A spring connected, two-part eyeglass temple shaft together with an operating sleeve which reciprocates longitudinally with respect to the temple shaft for flexing the spring and forcing the rear temple part against the wearer's head and for releasing the spring which then restores the original alignment of the temple parts. The sleeve also provides a rigid structural bridge between the temple parts.
