Ambient air pollution is currently a significant environmental risk to health. Black carbon (BC) is a component of atmospheric particulate matter that has a diameter of less than 2.5 μm. Because of this small size, these particles tend to stay in the air longer and are prone to be inhaled. Long-term exposure to BC has been associated with health hazards, such as adverse birth outcomes, respiratory disease, diabetes, atherosclerosis, stroke, and decline in cognitive function.1 Ocular diseases, such as dry eye, have also been found to be associated with air pollution.2 However, whether ambient air pollution is associated with glaucoma or intraocular pressure (IOP) is unknown.
