In metropolitan cities like Delhi, Mumbai, and Bangalore, where air quality often dips into hazardous levels, individuals who rely on contact lenses are experiencing alarming rates of eye irritation, redness, blurred vision, and discomfort. The fine particulate matter in polluted air, including PM2.5 and PM10, dust, smoke, and chemical contaminants, directly adheres to the lenses and the tear film surrounding the eye. This combination disrupts natural moisture balance and acts as a breeding ground for bacteria, significantly increasing the risk of infections such as microbial keratitis, dry eye syndrome, and corneal ulcers. Unlike glasses that provide a barrier in front of the eyes, contact lenses sit in direct contact with the cornea, making them more vulnerable to pollution-related damage.

Eye care specialists strongly recommend several precautionary measures to mitigate these risks. First and foremost, switching to daily disposable lenses can dramatically reduce the buildup of pollutants and pathogens, as these lenses are replaced every day. Meticulous hygiene is critical: lenses should be cleaned with fresh, sterile multipurpose solutions — never tap water or saliva — and ideally cleaned mid-day if exposed to outdoor pollution. Additionally, wearing protective eyewear such as wraparound sunglasses helps shield the eyes from airborne particles and harmful UV rays, which can compound irritation.

Maintaining eye moisture is another crucial safeguard. Using preservative-free, hyaluronic acid-based lubricating drops every few hours helps flush out irritants and restore the tear film. Indoor environments should be kept humidified between 40-60% to minimize dryness, and contact lens cases must always be cleaned and stored properly. Hydration plays a key role too; drinking adequate water and consciously blinking frequently—especially for those spending hours in front of screens—can help preserve natural eye lubrication and comfort.

Certain practices should be strictly avoided to prevent serious complications. Contact lenses should never be worn when pollution levels soar (AQI above 200), as this exacerbates dryness and inflammation. Sleeping in lenses, topping up old cleaning solution, rubbing the eyes, and using eye makeup or swimming while wearing lenses are all risky behaviors that increase infection potential. At the first sign of redness, pain, or blurred vision, lenses must be removed immediately and professional medical advice sought within 24 hours to avoid permanent corneal damage.

Finally, a diet rich in omega-3 fatty acids found in fish and walnuts supports eye health by reducing inflammation. Regular comprehensive eye exams, including slit-lamp evaluations, are essential to detect early signs of pollution-related damage. By vigilantly monitoring air quality and adopting these expert tips, contact lens users can significantly reduce the risk of eye problems and safeguard their vision even in the most polluted urban environments.
