The Electronic Optic Ski Goggles.

Winner of the "Best of What's New" award from Popular Science magazine, these ski goggles use electronic optic technology developed for Air Force pilots, allowing the lenses to be manually adjusted from light to dark with the touch of a button, providing flexibility, comfort, and safety for skiers and snowboarders while ensuring exceptional image clarity. The goggle's design completely eliminates the need to carry multiple pairs with various tints to battle the danger and discomfort of snow or direct sun glare. Using LCD-like VALiD® lens construction--this is the only product currently using this technology--the tint goes from light to dark when the internal liquid crystals are activated by the built-in 6-volt battery. Meets Air Force requirements for daytime use. Rated for up to 200 hours of On-position use per battery. 4" H x 3" W x 7" L. (1/4 lbs.)
