If you do get sunburn eyes, the best treatment is avoiding the sun and using lubricating eye drops to realize the irritation. Usually in a few days to a week, the symptoms will disappear. If not, or if the pain is heavy and conditions get worse, you should go to see you doctor immediately. And during daily life, you'd better take some measures to protect your eyes. It's simple as the American Optometric Association recommends to wear good-quality sunglasses and a hat with a wide brim, even on cloudy days. Sunglasses that screen out 75 to 99 percent of visible light and block at least 95 percent of ultraviolet A and 99 percent ultraviolet B radiation is good for eye protection against sun. And neutral gray lenses are the best color for lenses, because they reduce light intensity without altering the color of objects. Brown or amber lenses maybe are better for people who are visually impaired or for athletes because they increase contrast while reducing light intensity.
