As temperatures rise across Bengaluru, eye specialists are cautioning the public about the increased risk of ultraviolet (UV) radiation–related eye damage. Prolonged exposure to UVA and UVB rays can lead to both acute and chronic ocular conditions, some of which may affect vision if left unaddressed.
Common UV-induced conditions include photokeratitis, a painful “sunburn” of the cornea and conjunctiva, presenting with redness, tearing, blurred vision, and light sensitivity. This can occur not only under direct sunlight but also due to reflection from surfaces such as water, sand, and even concrete.
Chronic exposure may contribute to the development of pinguecula and pterygium, degenerative conditions of the ocular surface associated with UV radiation, dust, and dry environments. In the long term, cumulative UV exposure is also a known risk factor for cataract formation, macular degeneration, and periocular malignancies.
“While many of these conditions are manageable, prevention is far more effective than treatment,” says Dr. Rohit Shetty, clinician-scientist and Director at Narayana Nethralaya Eye Hospital. “Simple protective measures can significantly reduce the risk of UV-related eye damage.”
Eye Protection Guidelines for Summer:
* Use sunglasses that block 100% of UVA and UVB rays (UV400 certified).
* Prefer wraparound designs for enhanced protection.
* Wear wide-brimmed hats when outdoors.
* Maintain adequate hydration.
* Avoid prolonged exposure to direct air conditioning; consider humidification in dry environments.
* Use preservative-free lubricating eye drops when needed.
Narayana Nethralaya emphasizes that awareness and preventive care are essential to safeguarding vision, particularly during peak summer months when UV exposure is at its highest.
