Most of us know the importance of protecting our skin from the sun.

But what about our eyes?

It might sound surprising, but yes — your eyes can effectively become "sunburnt" after too much exposure to ultraviolet (UV) light. The condition is known as photokeratitis, and while it's usually temporary, it can be painful and is a reminder of just how important eye protection can be.

What is photokeratitis?

Photokeratitis is essentially a sunburn of the eye's surface.

It occurs when the cornea — the clear outer layer at the front of the eye — is exposed to high levels of UV radiation.

Just as skin can become red and irritated after too much sun, the eyes can react to excessive UV exposure too.

While it is often associated with bright sunny days, photokeratitis can also occur after exposure to reflected UV light from surfaces such as:

• Water
• Sand
• Snow
• Pavements
• Glass buildings

This means your eyes can be exposed to significant levels of UV radiation even when you don't feel particularly hot.

What are the symptoms?

Symptoms don't always appear immediately and may develop several hours after exposure.

Common signs include:

• Eye pain or discomfort
• Redness
• Sensitivity to light
• Excessive watering
• Blurred vision
• A gritty or sandy sensation in the eyes
• Headaches

If symptoms are severe or persist, it's important to seek professional advice.

It's not just a holiday problem

Many people assume UV-related eye damage only happens abroad or during extreme weather.

In reality, UV rays reach us all year round — even on cloudy days in the UK.

Up to 80% of UV rays can pass through cloud cover, meaning your eyes may still be exposed when the sun isn't visible.

This is why regular eye protection matters, not just during summer holidays.

The long-term effects of UV exposure

Photokeratitis is usually temporary, but repeated UV exposure over many years can contribute to longer-term eye health concerns.

Research has linked cumulative UV exposure to an increased risk of:

• Cataracts
• Pterygium (growths on the eye's surface)
• Damage to the retina
• Age-related eye conditions

Protecting your eyes today can help support healthy vision in the future.

Myth vs Reality

Myth: "My eyes can't get sunburnt."

Reality: The surface of the eye can be damaged by excessive UV exposure, leading to photokeratitis.

Myth: "It's cloudy, so I don't need sunglasses."

Reality: UV rays can still reach your eyes through cloud cover.

Myth: "Darker lenses provide better protection."

Reality: Lens colour doesn't determine UV protection. Always look for sunglasses that provide full UV protection.

Myth: "I only need sunglasses on holiday."

Reality: Everyday exposure adds up over time, whether you're walking, driving or spending time outdoors locally.

How to protect your eyes from UV damage

Fortunately, protecting your eyes is simple.

Choose sunglasses with full UV protection

Look for sunglasses that block 100% of UVA and UVB rays. This is one of the most effective ways to reduce UV exposure.

Wear a hat or cap

Brimmed hats help reduce direct sunlight and glare reaching your eyes.

Take extra care around reflective surfaces

Water, sand and snow can significantly increase UV exposure by reflecting light back towards the eyes.

Don't forget children

Children's eyes are more sensitive to UV light than adults', making good-quality sunglasses particularly important during outdoor activities.

A small habit that makes a big difference

Most of us remember sunscreen before heading outdoors.

Adding sunglasses to that routine can help protect your vision both now and in the years ahead.

Your skin isn't the only thing that needs protecting from the sun.

Protect your eyes this summer

Whether you're planning a holiday, enjoying a day at the beach or simply spending more time outdoors, the right sunglasses can help protect your eyes from harmful UV rays.
