The Dangers
of UV Light

Exposure to UV light occurs even
when we’re not in the sun.
It can lead to a range of
eye conditions and diseases.

to UV

Your eyes are the only internal tissue in your body exposed to UV light.
They are exposed every day of the year, even in cloudy conditions.

Overexposure to daylight can lead to a variety of eye problems – some of them serious.
These include:

  • What is it: A painful eye condition that affects the surface of the cornea, effectively sun-burning the eye. It is triggered by very bright snowy conditions, or when sunlight reflects off sand and water. 
  • How to spot it: Pain, redness, light sensitivity, headaches, halos.
  • Treatment: It should disappear naturally over a few days – avoid wearing contact lenses. Keeping away from sunlight and using eye drops can help. If the problem persists, stronger antibiotic eye-drop may be prescribed.

  • What is it: People who spend long hours outdoors – particularly in intense sunlight – may develop growths on their eyes, called pterygium. Those most at risk include farmers, skiers, fishermen and surfers. That’s why the condition is known as ‘surfer’s eye’.
  • How to spot it: Redness, inflammation, foreign body sensation, dry and itchy eyes.
  • Treatment: Discomfort from growths can be treated with eye drops or irradiation of the eye. Surgery is only required at an advanced stage.

  • What is it: Cloudy patches on the lens of the eye. Age is the biggest risk factor, but overexposure to daylight also increases the likelihood of developing cataracts.
  • How to spot it: Blurred, cloudy, misty or double vision, poor night vision, sensitivity to light, halo effect, and a yellow or brown tinge to the sight.
  • Treatment: Surgery to replace the affected lens with an artificial one.

  • What is it: Radiation in UV light is absorbed by the lens of the eye. In rare cases, this can contribute over time to the development of eye cancer.
  • How to spot it: Blurred vision, flashing lights, or an appearance of orange pigment on the surface of the eye.
  • Treatment: Radiotherapy to destroy cancerous cells (while maintaining as much vision as possible). Surgery may also be necessary.

Protect your eyes just like your skin

Look out for an Eye-Sun Protection Factor (E-SPF) rating on lenses. As with SPF in sunscreen,
a higher E-SPF means more protection for your eyes.

E-SPF® is a global index rating the overall UV protection of a lens.
E-SPF® was developed by Essilor International and endorsed by 3rd party experts.
A lens rating of E-SPF® 25 means that an eye protected by the lens will receive
25 times less UV exposure than an unprotected eye.
