<p>Spectacles side piece ensures firm fit for swimming, running, jumping, etc. and has hollow-shaped channel at one end. A pre-shaped length of wire is pushed into and pushed out of the hollow-shaped channel. In the pushed-out state, the wire wraps itself closely round the lower part of the ear and thus gives the spectacles a firm fit.

A small plate-like attachment is used for pulling-out the wire.</p> |
