Study review links PM2.5 air pollution to higher risk of glaucoma and cataracts

We often think of air pollution as a burden for the lungs or the heart, organs tucked safely inside the chest. But the eyes are different; they are our most direct point of contact with the outside world. Recent evidence suggests that this constant exposure may leave our vision vulnerable to the very air we breathe. An extensive analysis of 41 studies, covering millions of people across East Asia and the United Kingdom, has identified a statistical link between air pollution and the development of eye diseases. While aging remains the primary risk factor for vision loss, the data indicates that long-term exposure to fine particulate matter-specifically PM2.5-increases the likelihood of developing glaucoma and cataracts. The invisible irritant Researchers looked at a variety of pollutants, including nitrogen dioxide, sulfur dioxide, ozone, and carbon monoxide. However, the most distinct association emerged with PM2.5-particles measuring 2.5 micrometers or less. These particles are small enough to bypass many of the body's natural filters.

Research review finds people living in most polluted areas suffer 70 per cent higher odds of glaucoma

A review of 41 studies found that higher exposure to air pollution was linked to greater odds of glaucoma and cataracts, with PM2.5 pollution showing the clearest association.
