Its subtype, air pollution, encompasses the burning of fossil fuels (coal, gas, oil) and wildfires, that release toxic gasses in the environment. Indoor, air pollution, on the contrary, involves burning fireplace and home cookstoves that use gas, coal and biomass fuels.Does High AQI Affect Eye Health? High Air Quality Index (AQI) and air pollution can significantly affect eye health. Exposure to pollutants like particulate matter (PM), ozone, and nitrogen dioxide irritates the eyes, leading to discomfort, dryness, redness, and even more serious conditions over time. The tiny particles present in polluted air can penetrate the eyes, causing inflammation and potentially leading to long-term damage, such as conjunctivitis, cataracts, or increased risk of eye infections. People with pre-existing conditions like dry eyes, allergies, or asthma are particularly vulnerable.Prolonged exposure to poor air quality can also exacerbate symptoms of eye conditions, including eye strain, irritation, and blurry vision. Those living in areas with high air pollution may notice increased eye sensitivity, particularly during peak pollution times, like smog-filled days.To protect your eyes from the harmful effects of air pollution, here are some preventive measures to follow:Wear Sunglasses: Sunglasses can act as a protective barrier, reducing direct exposure to UV rays and airborne irritants. Opt for sunglasses with a wraparound design for maximum protection.Use Lubricating Eye Drops: To combat dryness and irritation, use lubricating eye drops to keep your eyes moisturized, especially if you are exposed to polluted environments.Stay Indoors During High Pollution: Check air quality levels regularly and stay indoors when pollution levels are high, especially during morning or evening rush hours.Keep Windows Closed: On days with high pollution, keep your home or car windows closed to prevent pollutants from entering.Invest in an Air Purifier: Using an air purifier with a HEPA filter in your living and working spaces can help reduce indoor air pollution, improving overall air quality.Practice Good Eye Hygiene: Regularly wash your face and hands to remove any pollutants, and avoid rubbing your eyes to prevent irritation and infection.
