Why you should protect your eyes when air pollution levels are high

The Washington Post spoke to Lina Mu about reports on why people should protect their eyes when air pollution is high. Mu notes that while there are many studies detailing how polluted air is bad for hearts and lungs, very little is known about the effects of dirty air on the eyes. Mu suggests wearing sunglasses, using lubricating eye drops, washing hands often and avoiding rubbing your eyes on days when air pollution levels are high, so as not to exacerbate any irritation. Amy Millen, associate professor in the Department of Epidemiology and Environmental Health, also suggests eating an antioxidant-rich diet.
