How Pollution Affects Your Vision: What You Need to Know

Air pollution is a growing concern in many communities today, and while many people are aware of its impact on the lungs, its effects on vision are often overlooked. But in fact, airborne particles and chemicals can cause a variety of vision-related problems.¹

How Does Pollution Affect Vision?

Pollution affects vision through irritation and inflammation of the eyes. Pollutants can damage the surface of the eye and lead to oxidative stress. When contaminants come into contact with the eyes, they can disrupt the film that protects the surface of the eye, making the eyes more susceptible to irritation and infection.¹

What Problems Can Pollution Cause in Vision?

Several vision-related issues may emerge due to pollution, including:

Dry Eye (most common): Polluted air can reduce tear production, causing dryness and a gritty sensation.²
Allergic Conjunctivitis: Chemicals and allergens in the air can lead to inflammation of the conjunctiva—causing eye watering, itchiness, and redness.
Increased Risk of Cataracts and Age-Related Macular Degeneration: Long-term exposure to air pollutants has been linked to early onset age-related macular degeneration and cataracts.
Eye Fatigue and Blurred Vision: Polluted environments can cause eyestrain, and blurred vision.³

How to Protect Yourself from the Negative Effects of Pollution

Protecting your eyes from pollution involves preventative care and good hygiene. Here are a few helpful tips:

Wear Protective Eyewear: Sunglasses or protective eyewear, such as goggles, can shield your eyes from airborne pollutants.
Limit Outdoor Activity on High Pollution Days: Check local air quality reports and avoid spending time outside when pollution levels are extreme.
Keep Eyes Moist: Ask your Eye Care Provider for their recommended over-the-counter lubricating eye drops to help keep your eyes hydrated.
Practice Good Hygiene: Wash your hands frequently and avoid touching your eyes. If you wear contact lenses, be sure to clean them regularly.
Use an Air Purifier Indoors: Keeping indoor air clean can reduce exposure to harmful pollutants, benefiting both your lungs and your eyes.³

Pollution can significantly impact vision health, leading to discomfort and long-term vision issues. Protecting your eyes can help maintain clear, healthy vision even in environments with high levels of pollution.
