These Randolph Archer sunglasses are similar to the classic Aviator, but with a sleek metal styling and wrapped lenses that cover a larger range to prevent light from entering the eye. They feature SkyForce-P™ Lite Lens™ technology which results in 15% lighter frames! They also have Vector™ Anti-Reflective backside coating and Blue Wave™ HEV Blue Light Management. These sunglasses were originally built for the U.S. Military, so they are made to the highest military-spec standards. There is no question that they can survive anything--even on your most rigorous and demanding days! All Randolph frames are handcrafted in the USA and include a lifetime warranty.
