Patent

CA 2184573

A light shield is provided which includes a relatively thin but preferably rigid body of light permeable material. An arrangement is interposed between the body of light permeable material and one side of the lens to mount the shield directly on the lens in light intercepting relationship relative to the eye of a user of the lens. The shield which is preferably mounted in generally cantilever manner on the lens is removable and can be reinstalled repeatedly. Preferably an adhesive is used which provides for a minimum of residue on the lens and the shield is preferably affixed to the lens in such a way that there is a minimum of optical interference.

L'invention concerne un filtre de protection contre la lumière (32 et 34) comportant un corps relativement mince mais, de préférence, rigide en matériau perméable à la lumière. Un dispositif est intercalé entre ledit corps et un côté du verre de lunette (28 et 26), de façon à monter le filtre de protection directement sur le verre, afin d'intercepter la lumière par rapport à l'oeil de l'utilisateur. Le filtre de protection (32 et 34) monté, de préférence, en porte-à-faux sur le verre, est amovible et peut être réinstallé de façon répétée. On utilise, de préférence, un adhésif ne laissant qu'un minimum de traces sur le verre et on fixe, de préférence, le filtre de protection au verre de manière à limiter au maximum l'interférence optique.
