Comfortable and stylish, the Global Vision Lieutenant Military Ballistic Safety Sunglasses will protect your vision from shop to road and have passed military ballistic testing to meet military specifications. These safety sunglasses feature cutting-edge technology that goes above and beyond UV protection, offering protection from 99 to 100 percent of harmful light. They have also earned an ANSI Z87.1-2010 Standards for use in industrial applications rating because they have endured extensive testing for optical clarity, impact resistance and proper eye coverage. The black nylon open frame features high flexural strength and superior wear resistance and the smoke-colored lenses are of shatterproof polycarbonate with a scratch-resistant coating. This durability allows them to withstand forces that would damage other eyewear.
