<p>A double-sided looking glass (1) for ski goggles with a curved outer glass (2) and an equally curved inner glass (3) placed at a distance from the outer glass (2) made from a sheet of cellulose propionate and connected to the outer glass (2) by means of an edged sealing strip. The invention is characterised in that both the outer glass (2) which is made of injected polycarbonate and the inner glass (3) which is made from vacuum- formed cellulose propionate are spherically curved and that the outer glass (2) has a hygroscopic coating (7) on the inside.</p> |
