No more tears, the comfortable foam seal blocks out irritating vapors and the slightly tinted and fog-free lenses add to the maximum clarity of the goggles. These multi functional goggles can be used for yard work, bike riding, skiing and for dry eye as well! The comfortable unisex patented design fits snugly on most face shapes. Will not fix over eyeglasses. Wipe goggles clean with a clean lint free cloth.
