FIELD: physics.
SUBSTANCE: binary rim device comprises a bridge, nose pads, frames and temples. The feature is that the bridge is made by twisting the two dissimilar metal workpieces of different diameter and length from the center to the edges, and the nose pads and frames are formed by its peripheral ends, connected to the temples and the lenses. Herewith the frames may be rimless, semi-rimless or full-rim.
EFFECT: increasing the reliability of the frame construction by eliminating soldering, and providing the additional possibilities to control landing of the left and the right rim halves, taking into account the asymmetry of the anthropometric parameters of the eye position.
