Air pollution could be harming children’s eyesight, study finds
Experts make new link between children’s eyesight and air pollution
- Air pollution, specifically nitrogen dioxide and fine particulate matter, has been linked to impaired eyesight in children, particularly short-sightedness.
- A study by the University of Birmingham found that children living in areas with cleaner air exhibited better vision, with primary school children showing the greatest improvements.
- Researchers explained that polluted air can cause inflammation and stress in the eyes, reduce beneficial sunlight exposure, and trigger chemical changes leading to myopia.
- The study identifies air pollution as a significant and modifiable risk factor for childhood myopia, alongside genetics and screen time.
- Experts suggest interventions such as installing air purifiers in classrooms and creating 'clean-air zones' around schools to improve air quality and protect children's vision.
