Click to see image  LA Lenses - Light adjusting grey lenses make this protective eyewear perfect for missions where you don't have time to think about your eyes. The innovative Seal-Tek system seals your eyes from outside elements and allows you to determine the configuration. The result is comfortable, durable goggles that provide clear, unobstructed vision in any light conditions. These light adjusting lenses darken on bright sunny days to shield the eyes from harmful Ultra Violet rays. On overcast days or at night the lenses adjust to clear for perfect optical clarity. Now you don't have to stop to interchange lenses. This new technology is also produced using shatterproof polycarbonate. This is much different than the old photochromic lens technology that use glass and CR-39, which can shatter if struck by a rock while riding. Wiley X has also incorporated the new Emerald 4 anti-reflective coatings to eliminate back-lit glare from the sun or car headlights truly giving the wearer the most functional riding lens available.
