Summer & UV Eye Damage: What Chennai Heat Does to Your Eyes
By Dr. Rajeswari • Thu Jun 18 2026
Chennai’s summer sun is intense, and prolonged UV exposure does more than cause discomfort — it can contribute to long-term eye damage that often goes unrecognized.
How UV exposure affects your eyes
Years of cumulative UV exposure are linked to a higher risk of cataracts forming earlier in life, as well as pterygium (a growth of tissue on the eye’s surface, common in people with significant outdoor sun exposure) and contributing factors for macular degeneration.
Immediate effects of intense sun and heat
Beyond long-term risk, summer heat and glare can cause immediate eye strain, dryness, and irritation — particularly for those who spend long hours commuting or working outdoors.
Practical protection
- Wear sunglasses that block UV-A and UV-B rays, not just dark-tinted lenses
- A wide-brimmed hat adds meaningful additional protection
- Stay hydrated — dehydration worsens dry eye symptoms in hot weather
- Avoid looking directly at bright reflective surfaces like water or pavement for extended periods
Who should be especially cautious
Outdoor workers, daily commuters, and anyone with a family history of cataracts or macular degeneration should be particularly diligent about UV protection, starting well before any symptoms appear.
When to get checked
If you notice persistent redness, a visible growth on the white of your eye, or worsening glare sensitivity, it’s worth a proper evaluation rather than assuming it’s “just the heat.”
