The aftermath of Diwali has enveloped Delhi in dense smog, with air quality indices consistently registering in the “very poor” to “severe” categories since the festival. Ophthalmologists throughout the capital have documented a sharp 60% increase in eye-related consultations. Patients present with symptoms including intense itching, redness, burning sensations, excessive tearing, and dryness. The combination of firecracker emissions, vehicular exhaust, and suspended particulate matter has severely compromised ocular health across all age groups.

Vulnerable populations, including children, outdoor workers, and the elderly, are experiencing heightened risks. Particulate matter PM2.5 and PM10 directly deposits on the corneal surface, disrupting the tear film and triggering inflammatory responses. Prolonged exposure may lead to chronic conditions such as allergic conjunctivitis, keratitis, or persistent dry eye syndrome. Medical experts emphasize that untreated irritation can progress to secondary infections or temporary visual impairment.

Dr. Harbansh Lal, Chairman of Delhi Eye Centre, reports a 50–60% rise in patient volume, with many exhibiting acute allergic reactions. Individuals with pre-existing dry eye conditions face exacerbated symptoms due to chemical pollutants destabilizing tear film integrity. Contact lens wearers and those using eye makeup are advised to abstain, as these increase pollutant retention and corneal abrasion risk.

At AIIMS RP Centre, Dr. Rajesh Sinha confirms a 50% surge in cases of dryness, burning, and watery eyes, even among previously unaffected individuals. Gases such as nitrogen dioxide and sulfur dioxide react with ocular moisture, inducing chemical conjunctivitis. Traffic police, delivery personnel, and students commuting through polluted corridors constitute high-exposure cohorts requiring immediate protective interventions.

Preventive protocols issued by specialists include instilling preservative-free lubricant drops, wearing protective eyewear with side shields, and adhering to frequent facial hygiene. Indoor air filtration and restricted outdoor activity during peak pollution hours are strongly recommended. Healthcare authorities urge prompt consultation for persistent symptoms to avert long-term ocular damage. Delhi’s annual post-Diwali pollution spike underscores the critical need for sustained environmental and public health safeguards.
