<p>The spectacle frame leg (1) has a plastics body, with an internal metal wire. It has circular grooves (4) and half grooves (5) at the end remote from the frame. The grooves mainly are formed in a part not in contact with the ear. A small number are in contact with the ear and the half grooves are on the leg side away from the ear. The groove and half groove shapes are identical to improve the gripping of the ends of an elastic strap, connecting the leg ends.</p> |
