CA 2322475

The description relates to a double lens (1) for skiing goggles with a curved outer lens (2) and an equally curved inner lens (3) made of a cellulose propionate foil, arranged at a distance from the outer lens (2), which is connected with the outer lens (2) via a sealing tape (4) at the edge. To ensure a favorable fogging behaviour it is suggested that both the outer lens (2), made of injection-molded polycarbonate, and the inner lens (3), made of a vacuum-formed cellulose propionate foil, are curved spherically and that the outer lens (2) is provided with a hygroscopic coating (7) at its inner side.

L'invention concerne un verre à double paroi (1) pour lunettes de ski, comprenant un verre extérieur incurvé (2) et un verre intérieur (3), également incurvé, placé à distance du verre extérieur (2), constitué par une feuille de propionate de cellulose et relié au verre extérieur (2) par l'intermédiaire d'une bande d'étanchéité périphérique (4). En vue de garantir une garniture avantageuse, l'invention est caractérisée en ce que le verre extérieur (2) moulé par injection en polycarbonate, et le verre intérieur (3) fabriqué par formage sous vide de la feuille de propionate de cellulose sont tous deux incurvés sphériquement, et en ce que le verre extérieur (2) présente, sur sa face interne, un revêtement hygroscopique (7).
