How to protect your eyes from pollution

Pollution can have a significant effect on your eyes, causing discomfort and irritation and even long-term damage. This guide explains how pollution affects the eyes and gives practical tips to protect them and keep them healthy.

How pollution affects your eyes

Pollution, including particulate matter, dust, smoke and chemical pollutants, can cause several eye problems:

• Eye irritation: exposure to pollutants can make the eyes red, itchy and dry.
• Allergic reactions: pollutants can trigger allergic conjunctivitis, causing inflammation and discomfort.
• Higher risk of infection: polluted surroundings can weaken the eye's natural defences and increase the risk of infections.
• Long-term damage: long exposure to pollutants can contribute to more serious conditions, including dry eye disease and macular degeneration.

Tips to protect your eyes from pollution

1. Wear protective eyewear

• Sunglasses: choose sunglasses with UV protection to shield your eyes from harmful rays and reduce exposure to airborne particles.
• Goggles: if you work or spend time where there is a lot of dust or chemicals, consider wearing protective goggles.

2. Use artificial tears

• Keep your eyes moist: dry air and pollution can dry out your eyes. Lubricating eye drops help keep them moist and comfortable.
• See a specialist: if dryness or irritation persists, consult an eye specialist for advice suited to you.

3. Keep good hygiene

• Wash your face: regularly wash your face and eyelids with clean water to remove dust and pollutants.
• Don't touch your eyes: avoid touching your eyes with unwashed hands, so that you don't transfer pollutants and bacteria.

4. Use air purifiers

• At home: air purifiers with HEPA filters reduce indoor pollutants and improve air quality.
• Clean regularly: keep your home clean and dust-free to reduce airborne particles.

5. Stay hydrated and eat well

• Drink water: enough water helps keep the eyes moist and supports overall health.
• Healthy diet: include foods rich in omega-3 fatty acids and vitamins A, C and E, which support eye health. See nutrition and diet for healthy eyes.

6. Protect your eyes outdoors

• Avoid peak pollution: limit outdoor activities when pollution is high, such as during smog or dust storms.
• Choose cleaner places: for outdoor activities, pick areas with less pollution and better air quality.

7. Have regular eye check-ups

Regular eye examinations can detect early signs of damage from pollution and other causes. See what a comprehensive eye examination includes.
