New Study Links Air Pollution to Vision Problems

A new study in the UK adds to the scientific literature connecting eyesight problems with increased air pollution, The Hill reports.

In the study, published in the British Journal of Ophthalmology, scientists observed more than 115,000 volunteers between the ages of 40 and 69 to gauge if increased amounts of nitrogen dioxide and nitrogen oxides were linked to age-related macular degeneration (AMD) or the deterioration of the retina that results in impaired vision.

Nitrogen dioxide is largely a product of man-made traffic and industrial activity. When controlling for potential variables, such as smoking or prior health problems, the results indicate that the participants who were exposed to a higher volume of tiny particles of air pollution reported more eyesight problems.

Researchers also found that higher PM levels were associated with thinner pigmented retinal layers.
