Exposure to Urban Air Pollution Particulate Matter and Ocular Disorders

About 90% of the world's population is exposed to air pollutants beyond the limits of the World Health Organization (WHO) recommended. Due to regular contact of atmospheric air with the cornea, tear the film, and conjunctiva, the pollutants present in the air have direct access to these ocular structures. Exposure to different parts of the eye to polluted air results in burning and redness of the eye, ocular disorders, and several other problems. Several studies have shown the drastic impact of air pollution on the eyes. In addition to these short-term effects, air pollution can also affect eyesight. Recently studies have linked air pollution exposure with the risk of glaucoma. Based on these findings of inner retinal changes, the Exposure to urban air pollution particulate matter and ocular disorders suggests that PM2.5 may be an independent risk factor for glaucoma. The effects of air pollutants on the eyes are thought to be limited to the surface of the eye and simple eye irritation. While exposure to air pollution has a much greater impact on the eyes than we think. In this mini-review, we investigated ocular disorders following exposure to air pollution particulate matter.
