Air Pollution and Eye Irritation: Exploring the Link and Solution

The eye is a delicate organ with a large part of it exposed to the environment, which makes it quite vulnerable to the harmful effects of air pollution. That’s why when air pollution levels increase, many people complain about eye irritation and other eye-related problems. It is, therefore, important to understand the connection between air pollution and eye health, and take proactive measures to safeguard your eyes.

Understanding Air Pollution

Air pollution, particularly in urban areas, often contains various airborne particles and chemicals that can irritate the eyes. While particulate matter, such as tiny dust particles, can physically irritate the eyes and lead to symptoms such as itching, burning, and redness; chemical pollutants such as nitrogen dioxide and volatile organic compounds can also trigger eye irritation. Additionally, air pollution can exacerbate allergies, leading to symptoms such as watery eyes. 

Eye Problems Related to Air Pollution

Prolonged exposure to air pollution can significantly affect eye health leading to the development of various eye problems, such as:

Conjunctivitis

Conjunctivitis, also known as “pink eye”, is a condition that occurs when the conjunctiva, the clear membrane covering the white part of the eye, becomes inflamed due to exposure to allergens, such as pollen, dust, and chemicals in polluted air. Common symptoms of conjunctivitis include, redness, itching, tearing, and swelling of the eyes.

Dry Eye Syndrome

Airborne pollutants can disrupt the tear film that keeps the eyes lubricated, leading to dryness and irritation. Some of the common symptoms of dry eye syndrome include a gritty or burning sensation in the eyes, blurred vision, and redness.

Pterygium (Surfer’s Eye)

This type of eye disease is caused due to a fleshy, wedge-shaped growth of tissue on the conjunctiva, which gets worse upon prolonged exposure to UV rays, wind, dust, and pollution. This type of eye disease is common among outdoor enthusiasts, who spend extended time outdoors, particularly in sunny or windy environments.

Eye Irritation and Redness

Coming in direct contact with airborne pollutants can lead to general eye irritation, causing discomfort in day-to-day life. The affected person can experience redness, burning sensation, tearing, and sensitivity to light.

How to Protect Your Eyes from Air Pollution?

It is important to protect your eyes from air pollution, especially in areas where air quality is poor. Here are some effective strategies:

Wear Protective Eyewear

• Sunglasses: Use sunglasses that provide UV protection and snuggles around the eyes blocking harmful UV rays and airborne particles from entering the eyes.
• Safety Glasses: If you're in a highly polluted environment or involved in outdoor activities such as construction, it is important to wear safety goggles to protect your eyes from dust and debris.

Create a Clean Indoor Environment

Use air purifiers with HEPA filters in your home to reduce indoor pollutants and allergens. In addition, ensure proper ventilation while minimising outdoor air entry during high pollution days. Use exhaust fans and keep windows closed when air quality is poor.

Use Lubricating Eye Drops

Over-the-counter artificial tears is another effective way to protect your eyes. It keeps your eyes moist and wash away irritants. That said, it is important to ensure that you use preservative-free options. 

Stay Indoors When Air Quality Index is High

Keep an eye on the air quality index in your area and limit outdoor activities when pollution levels are high. Staying indoors can significantly reduce exposure to pollutants.

Drink Plenty of Water

Staying hydrated helps maintain tear production, keeping your eyes lubricated and reducing dryness caused by air pollution.

Practice Good Eye Hygiene

Regularly wash your face and eyelids with clean water to remove any pollutants that may have settled on your skin and eyes. In addition, avoid rubbing your eyes, as it can irritate your eyes further and introduce more allergens or pollutants.

Consume Antioxidant-Rich Foods

Incorporate foods rich in vitamins C and E, omega-3 fatty acids, and other antioxidants into your diet. These nutrients can support eye health and may help combat oxidative stress caused by pollution.

Limit Screen Time

If you’re working on a computer or using screens for long periods, follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This can help reduce eye strain.

Use Humidifiers

Using a humidifier can help maintain moisture in the air, especially in dry indoor environments, which can prevent your eyes from becoming dry and irritated.

Regular Eye Check-Ups

Regular visits to an eye care specialist can help detect any potential problems early and provide personalised advice on protecting your eyes.

Natural Remedies to Soothe Irritated Eyes

If you’re experiencing eye irritation several natural remedies can help soothe your eyes and alleviate discomfort. Here are some effective options:

Cold Compress

A cold compress can reduce inflammation and provide immediate relief from irritation. All you have to do is soak a clean cloth in cold water, wring it out, and place it over your closed eyes for 10-15 minutes. You can also use chilled cucumber slices for added soothing effects.

Tea Bags

Tea, especially chamomile or green tea, contains anti-inflammatory properties that can help reduce irritation and redness. Steep tea bags in hot water, allow them to cool and then place them over your closed eyes for about 10-15 minutes.

Aloevera

Aloevera has soothing and anti-inflammatory properties that can help calm irritated eyes. Extract fresh aloevera gel and apply a small amount around the eye area (avoiding direct contact with the eyes). Rinse after 10-15 minutes.

Cucumber Slices

Cucumbers have a high water content and soothing properties that can help relieve puffiness and irritation. Place cool cucumber slices over your eyes for about 10-15 minutes to refresh and soothe.

Hydration

Staying hydrated helps maintain optimal tear production and prevents dryness. Drink enough water throughout the day to keep your body and eyes hydrated.
