The spectacle frame for rimless lenses (1) made from organic glass, consists of a nose bridge and side pieces connected to the lenses by front (2, 3, 4) and rear (5, 6, 7) bars, fastened by bolts (11). The front bars have spikes (8) to grip the lenses, and cavities to receive the spikes can be made in the lenses before the frame components are fitted to make for more convenient positioning. The rear bars on the side pieces can be positioned with the aid of holes (9) or rings (10).
