Glasses that adapt to lighting conditions have been around for a long time. For skiers who often ski from light to shade in a matter of seconds however, the lenses of phototropic ski goggles react too slowly. The liquid crystal lens of the ski goggles changes the light transmission under changing conditions in very little time. This light show is all powered by solar energy. This makes the POC Cornea Solar Switch the winner in the Snowsports segment in the Googles & Glasses category.
