Most of us don't think much about our eyes when we step out into the sun. We put on sunscreen. We carry an umbrella. Maybe even wear a cap if it's too hot. But the eyes? They usually get forgotten. Or we have not heard much about it. About using sunglasses every day, and the risks of UV exposure to the eyes.

The thing is, sunlight doesn't just affect the skin. The UV rays in sunlight can affect the eyes too. And unlike getting a tan or a sunburn, you may not notice what's happening. The damage often builds up slowly over the years.

Here is a fact that many of you are not aware of- maybe because it is not a topic of interest on social media. Driving to work, or walking to the nearby shop, whatever may be the activity. If you spend time outdoors every day, your eyes are getting exposed. So, UV protection isn't just for people going on a beach holiday. It's something all of us should think about.

UV rays: What are they?

Simply said, ultraviolet radiation. It's a part of sunlight that we can't see with our naked eyes.

There are different kinds of UV rays, but for the eyes, UVA and UVB are the ones that matter. Both can reach us from the sun. And no, a cloudy day doesn't completely block them.

Can sunlight really damage the eyes?

Yes. It can. Think of it this way. If your skin can get sunburned after too much sunlight, your eyes can react too.

One condition doctors see is called photokeratitis. It's basically a sunburn of the eye. The eyes become painful, watery, red, and very sensitive to light. It usually happens after intense UV exposure.

It isn't about one afternoon in the sun. It's years and years of exposure.

Over time, UV rays may increase the risk of cataracts. They can also lead to conditions like pterygium(where a fleshy growth develops over the white part of the eye). Some studies also suggest damage to the retina after prolonged exposure.

None of these happen overnight, which is probably why many people don't connect them with sunlight.

Who should be more careful? Those who work outdoors!

Farmers, construction workers, traffic police, delivery staff, drivers—anyone who spends several hours under the sun. Children too.

They rarely complain about sunlight unless it becomes uncomfortable.

People who enjoy trekking, cycling, fishing or beach trips should also remember that reflected sunlight can sometimes be just as strong.

Are there warning signs?

Sometimes.

Your eyes may feel irritated after a long day outside. They may water more than usual. Bright light may suddenly feel uncomfortable. You may even notice blurred vision for a while.

The problem is that many UV-related eye conditions don't announce themselves early. That's why regular eye check-ups matter just as much as prevention.

How do you protect your eyes?

A good pair of sunglasses is probably the easiest place to start. Not expensive sunglasses. Just ones that block 100% UVA and UVB rays.

That's more important than how dark the lens looks.

If you're outdoors for long hours, wear a hat too. It reduces direct sunlight reaching the eyes.

Parents should think about eye protection for children as well. We often remember sunscreen before a school trip, but sunglasses are easy to forget.

And don't leave them at home just because it's cloudy.

A few myths worth clearing up

"I only need sunglasses at the beach."

Not really.

Your daily commute probably exposes you to sunlight more often than your annual vacation.

"Darker glasses mean better protection."

Not always!

The UV filters are much more important than the color of the lens.

"It's cloudy today."

Even on cloudy days, you still have the risk of UV exposure.
