Smoke Gets in Your Eyes

Air pollution—already linked to an increased risk of lung cancer, stroke, heart disease, etc.—is now associated with a new risk: eye disease.

China Medical University in Taiwan researchers linked air pollutants nitrogen dioxide and carbon monoxide to a higher risk of developing age-related macular degeneration. 

Using air quality and health insurance data on nearly 40,000 urban residents over 50, the researchers found that those with highest NO2 exposures were almost 200% more likely to develop macular degeneration, and those with highest CO exposures had an 84% increased risk, according to the BMJ Journal of Investigative Medicine article.
