Yes, UV coating on sunglasses and eyewear shields your eyes from damaging UV rays. Without wearing UV-protective sunglasses or eyeglasses, even brief exposure to ultraviolet radiation can harm your eyes in ways comparable to a sunburn. Your eyes may turn red and puffy or feel gritty as if you have sand in them. Use a UV flashlight. If you have a UV flashlight or blacklight flashlight, you can test the lenses to see how effective they are. Turn out the lights and shine the UV light on the lenses. If the lenses have been treated, they shouldn't allow the light to pass through or may exhibit a faint blue-purple glow.
