Wear protective eyewear, such as sunglasses or safety goggles
Wearing protective eyewear is a crucial step in safeguarding your eyes from pollution. When spending time outdoors or commuting, particularly in a highly polluted environment, it is essential to keep your eyes covered with protective eyeglasses, sunglasses, or safety goggles.
Eyeglasses and sunglasses act as a barrier against harmful pollutants and UV rays, which can cause eye irritation, redness, and dryness. Look for sunglasses that wrap around your eyes and provide UV protection to block out harmful rays and airborne particles effectively. Safety goggles are especially important if you work in construction or a similar field, as they will protect your eyes from dust and debris.
If you wear contact lenses, consider switching to eyeglasses, as contact lenses may exacerbate irritation caused by pollutants. Additionally, if you have overly sensitive eyes, consider wrapping protective clothing around your eyeglasses for added protection.
It is also important to note that protective eyewear should not be your only defence against pollution. Practising good hand hygiene and avoiding touching your eyes are also crucial, as pollutants can be transferred to your eyes through your hands.

Stay indoors when pollution levels are high
Air pollution can cause a range of eye issues, from watery and itchy eyes to more serious conditions like retinal damage. To protect your eyes, it is recommended to stay indoors when pollution levels are high. Here are some detailed tips to help you do that:
Monitor Air Quality
Keep yourself informed about the air quality in your area. Check the Air Quality Index (AQI) or use apps like AirNow to stay updated. When the AQI exceeds 100, it's an alert for vulnerable groups to take precautions, and levels over 300 indicate very hazardous conditions for everyone. Staying aware of the AQI can guide your decision to stay indoors.
Avoid Outdoor Activities
On days with high pollution levels, avoid outdoor activities, especially strenuous exercises like running or mowing the lawn. Exposure to polluted air can irritate your eyes and cause discomfort. If you must go outside, keep your time outdoors brief and wear protective eyewear.
Plan Your Day Accordingly
Adjust your daily routine to limit your time outdoors when pollution levels are high. For example, if you enjoy morning walks, consider shifting your exercise routine to later in the day when pollution levels may be lower. Check the AQI and choose the safest time to venture out, if necessary.
Create a Healthy Indoor Environment
Even when you stay indoors, ensure that the indoor air quality is good. Avoid frying food, as it can increase indoor smoke, and refrain from smoking indoors. If you live in an area prone to wildfires, consider investing in a high-quality air purifier to markedly decrease indoor pollution levels. Keeping your indoor air clean is essential for eye and overall health.
Take Proactive Measures
In addition to staying indoors, be proactive with your eye care. Eat a healthy diet rich in vitamins, minerals, and omega-3 fatty acids. Stay hydrated by drinking plenty of water, which aids in tear formation and helps flush out toxins. Practice good hand hygiene to minimize the transfer of pollutants to your eyes. These proactive measures will help protect your eyes from the harmful effects of pollution.

Eat a healthy diet with omega-3 fatty acids and vitamins
Eating a healthy diet rich in omega-3 fatty acids and vitamins is crucial for eye health, especially when exposed to pollution. Omega-3 fatty acids are "good fats" that your body needs but cannot produce on its own. They are essential for brain and eye development and can be obtained from various dietary sources.
Fatty fish, such as salmon, are excellent sources of omega-3s, particularly the types known as EPA and DHA. The American Heart Association (AHA) recommends consuming at least two servings of fatty fish per week, with each serving being about 3 ounces. For plant-based options, ground flaxseeds and flaxseed oil are rich in ALA, another form of omega-3. Chia seeds, nuts, and healthy oils like canola oil are also good sources of omega-3 fatty acids.
In addition to omega-3 fatty acids, a diet rich in vitamins is vital for maintaining eye health. Vitamin A, for instance, is essential for good vision and the functioning of the cornea. Beta carotene, found in colourful fruits and vegetables, is a primary source of vitamin A. Vitamin E, a powerful antioxidant, helps protect the eyes from free radical damage and reduces the risk of developing cataracts.
Vitamin C is another crucial nutrient that safeguards the eyes against UV light damage and oxidative damage. B vitamins, including vitamin B1, B3, and B12, are also important for eye health. A deficiency in vitamin B3 has been linked to glaucoma, while vitamin B1 supplementation has been found to reduce symptoms of dry eye disease.
Lastly, staying hydrated is essential for eye health. Drinking plenty of water helps flush out harmful toxins and waste from the body, benefiting both your overall health and the health of your eyes.

Stay hydrated to maintain eye moisture
Air pollution can cause a range of eye problems, including dryness, redness, itchiness, watery eyes, and burning sensations. To protect your eyes from air pollution, it is important to stay hydrated, as this helps maintain tear production and prevents dryness.
Drinking plenty of water throughout the day is essential for keeping your body and eyes hydrated. Water helps flush out harmful toxins and waste from the body, improving overall ocular health. It is also important to remember that staying hydrated is not just about drinking water; it is also about consuming other fluids and eating foods that are high in water content. These can include fruits and vegetables such as cucumbers, watermelon, strawberries, and oranges.
In addition to staying hydrated, there are several other measures you can take to protect your eyes from air pollution. One important measure is to wear protective eyewear, such as sunglasses or safety glasses, when outdoors. These act as a barrier against harmful pollutants and UV rays. It is also recommended to limit your exposure to high pollution levels by staying indoors when possible and using air purifiers to improve indoor air quality.
Practicing good eye hygiene is another way to protect your eyes. This includes regularly washing your face and eyelids with clean water to remove any pollutants that may have settled on your skin and eyes. It is also important to avoid rubbing your eyes, as this can irritate them further and introduce more allergens or pollutants.
Lastly, maintaining a healthy diet rich in vitamins, fibre, and essential nutrients can support eye health and combat the oxidative stress caused by pollution. This includes incorporating foods rich in vitamins C and E, omega-3 fatty acids, and other antioxidants.
