The spectacle frame has a front face, with two lateral stubs, and two temples which each extend from a front end, arranged against one of the front-face stubs, to a free rear end, each temple having on the inside a rod whose front end is immobilized at the front end of the temple, the temple having driving and shaping means for driving the movable rear end of the rod by displacement in the free rear end of the temple and for thus modifying the curvature of the temple. The front end of the rod is connected to the front-face stub against which is arranged the front end of the temple, inside of which the rod extends.
