Abstract
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.
