Abstract

An eyeglasses includes a pair of lenses, a bridging member, a pair of temples with hook ends that have pivotal end sections, and a pair of coupling units interconnecting the lenses and the temples. Each of the coupling units is in the form of a bent wire, and has a coil-shaped end defining a chamber and a bend portion extending from the coil-shaped end. The pivotal end sections of the hook ends of the temples are received in the pivotal chambers in the coil-shaped ends of the coupling units so as to be turnable relative to the coil-shaped ends between extended and retracted positions.
