\ Abstract of the Disclosure In a spectacle frame made of plastic ma- terial, each lens of the spectacle is adapted to be held in a closed annular rim member by means of a bead which is fitted in an annular groove. The thickness of the rim member can be greatly reduced because the bead constitutes a closed annulus, which surrounds the rim member and has on at least one side of the rim member an inclined ramp surface. The annular groove is formed in each lens.
