Delhi's Hazardous Air Quality Severely Impacts Eye Health
Delhi’s air pollution, with AQI reaching hazardous levels, is causing a surge in eye problems including itching, burning, and watering. Ophthalmologists report a 50–60% rise in patients with eye irritation post-Diwali. Toxic pollutants damage the eye’s tear film and cause inflammation, posing risks especially to children, outdoor workers, and the elderly.
Delhi’s air quality has deteriorated to hazardous levels, with particulate matter (PM2.5 and PM10) far exceeding safe limits, equivalent to smoking nearly 10 cigarettes daily. Beyond respiratory risks, eye health is severely impacted, evidenced by a 50–60% increase in patients with symptoms like itching, redness, burning, and watering eyes after Diwali. Pollution disrupts the protective tear film on the cornea, leading to inflammation, dryness, and heightened risk of infections. Chemicals such as nitrogen dioxide and sulfur dioxide react with eye moisture to form mild acids, exacerbating irritation. Vulnerable groups include outdoor workers, children, and the elderly, as prolonged exposure can cause chronic eye inflammation and lasting damage. Ophthalmologists recommend protective measures like wearing glasses and using lubricating eye drops, and stress the importance of medical consultation for persistent eye issues to prevent complications. The toxic air environment poses a significant direct threat to ocular health alongside well-known respiratory dangers.
