Unlike typical darkening sunglasses that adjust to UV rays (which do not pass through car windows), these superior sunglasses adapt to light intensity to provide optimal eye comfort while driving. Photochromic pigments inside the lenses react to visible light as it comes through a windshield, lightening or darkening the lens to block 80% to 91% of the light. The polarized, copper-tinted lenses have an antireflective coating that eliminates glare and reduces eyestrain. An oil-repellent coating prevents fingerprints and causes water to slide off of the lenses instead of beading and impairing visibility. The lenses block 100% of UV-A, -B and -C rays and are scratch- and impact resistant. With a lightweight metal frame, adjustable nosepiece, smooth rubber temple pads, and a hard-sided travel case. 6" W x 1 3/4" D. (3 oz.)
