This invention relates to temples or end-pieces of temples for eyeglass frames. The temples are disclosed as having a wide variety of electrical and/or electronic components housed therein. Temples and hinges are also disclosed which attach to either the eyeglass frame itself or to the surface of a lens and which break apart from its attachment upon an impact without damage to the temple, the hinge, the frame, or the surface of the lens. A hinge is also disclosed for connecting a temple having a power source to an eyeglass frame and for providing an electrical connection with the frame only when the temple is opened.
