The increasing levels of air pollution in urban areas have significant implications for human health, particularly eye health. While the effects of air pollution on respiratory and cardiovascular systems are well-known, the impact on eye-related disorders is often overlooked. Pollutants like PM, NO₂, and SO₂ can lead to eye fatigue, discomfort, and long-term damage to ocular health.

Pollutants and Eye Exposure

Air pollution is a complex combination of solid particles and gases, with PM2.5 and PM10 posing the greatest risk to human health. PM2.5 can penetrate the body's defenses and enter the bloodstream, while pollutants like NO₂ and SO₂ also contribute to the deterioration of eye health.

Immediate Symptoms of Eye Fatigue

Pollution-induced eye fatigue can quickly manifest in heavily polluted environments, causing symptoms like dryness, burning, itching, and watery eyes. These symptoms result from exposure to harmful airborne particles that break down the protective tear film, leading to discomfort and impaired focus on daily tasks.

Long-Term Impact on Eye Health

Prolonged exposure to high levels of pollutants like PM2.5 and nitrogen oxides has been linked to severe eye conditions such as allergic conjunctivitis and glaucoma. Traffic-related pollutants increase the risk of cataracts and age-related macular degeneration, potentially leading to blindness. Pollution has also been associated with a higher prevalence of myopia.

Managing and Mitigating Eye Strain

While complete elimination of pollutant exposure may not be feasible, there are ways to reduce the effects of pollution-induced eye fatigue. Using protective eyewear, like glasses or sunglasses, can shield the eyes from direct exposure to particulate matter. Lubricating eye drops can help restore moisture to the eyes and alleviate symptoms of dryness and irritation.
