Air pollution increases the risk of glaucoma and cataracts in the eyes
Quick Look
An international research team has found that exposure to fine dust particles (PM 5.2) increases the risk of developing glaucoma and cataracts in the eyes, as the increase in the risk of glaucoma reaches 70% in areas with high pollution, as a result of inflammation and oxidative stress that affects the optic nerve and the lens of the eye.

Why It Matters
Air pollution is known to affect the heart and lungs, but the new study links it to eye diseases such as glaucoma and cataracts through mechanisms of inflammation and oxidative stress.
A research team from several countries has found that air pollution not only affects the heart and lungs, but also poses a risk to eye health.
Cataract in the eye
Researchers from several scientific bodies, including King Khalid Eye Specialist Hospital, King Fahad Medical City in the Kingdom of Saudi Arabia, the Canadian University of Toronto, and the American University of Utah, analyzed the results of 41 studies that included millions of people, and found that exposure to fine dust particles known as (PM 5.2) is associated with an increased risk of glaucoma and cataracts in the eyes.
The researchers explained that the risk of glaucoma increases in areas with high rates of air pollution, by up to 70% compared to other, less polluted areas.
Greater impact
The head of the study team stated in statements to the website "Health Day", which specializes in medical research, that fine dust particles lead to inflammation and a disease condition known as oxidative stress, and that exposure to pollution over the years affects the optic nerve associated with glaucoma and may lead to the occurrence of opacity in the lens of the eye (cataract).
The researchers stressed that these results indicate the need to pay attention to efforts to reduce air pollution and implement clean air standards, including increasing green spaces and reducing traffic density in cities.
Open Questions
- What are the safe doses of exposure to PM5.2 particles for eye health?
- Do other types of pollutants affect eye health in the same way?
- How effective are environmental policies in reducing the risk of pollution-related eye diseases?
