Air Pollution Linked to Eye Condition Affecting Millions, Scientists Warn
Air pollution's impact may extend beyond breathing, with researchers uncovering a surprising threat to long-term vision.
Air pollution may be linked to a higher risk of serious eye diseases, a new analysis of existing research suggests. The study, presented at the 44th Congress of the European Society of Cataract and Refractive Surgeons, examined data from millions of people across observational studies in East Asia and the United Kingdom. Researchers found that exposure to fine particulate matter (PM₂.₅) was consistently linked to a greater likelihood of developing glaucoma and cataracts.
People living in highly polluted areas had up to 70% higher odds of glaucoma and a 4% increased risk of cataracts for every meaningful increase in air pollution exposure. The evidence for age-related macular degeneration (AMD) was less consistent. The researchers propose that fine particles may trigger inflammation and oxidative stress, damaging the optic nerve or lens and contributing to eye disease.
They suggest stricter air-quality standards, pollution-reduction measures, and more green spaces in urban areas to mitigate these risks.
