The Electronic Tint Ski Goggles.

These ski goggles use electronic optic technology developed for Air Force pilots that adjusts the tint of the lenses from light to dark at the touch of a button, providing flexibility, comfort, and safety for skiers and snowboarders while ensuring exceptional image clarity. Perfectly compatible with helmets, the goggles completely eliminate the need to carry multiple pairs of goggles with various tints in order to adapt to changing light conditions. Its unique LCD-like VALiD lens construction permits the tint to change from light to dark in as little as 1/10th of a second when the internal liquid crystals are activated by two included CR2032 batteries that provide up to 200 hours of use. Hypoallergenic foam cushions the face and its deep frame shape accommodates eyeglasses. 4" H x 3" W x 7" L. (4 oz.)
