<p>Spectacles (1) and in particular rimless spectacles (1) benefit from the use of shape memory materials for components. A piece of potentially or already shape memory wire is treated by the present method to provide spectacle components with a portion (A) which has a shape memory reflex response whilst other portions (B) are rendered rigid. These rigid portions (B) are more able to act as mountings (8) for other components, such as nose pads (7) and for deformation adjustment of spectacles (1). The method is particularly suited to making a spectacles bridge (3; 3; 3) which include bends (9) to allow the bridge (3; 3; 3) to be secured to spectacles lenses (2) and features (8) to which nose pads (7) can be secured. The method renders the whole component rigid and then by selective heating provides a shape memory response to a portion (A) of the component.</p> |
