Just as the sun’s ultraviolet (UV) rays can damage skin, they can also harm the lens and cornea of the eyes.

UV radiation increases the odds of you getting cataracts, a clouding of the internal lens inside the eye which leads to diminished eyesight. It has also been linked to macular degeneration, a treatable but incurable disease of the macula, a part of the retina that is essential for sharp vision.

Other UV-related eye problems are pterygium and pingueculum. A pterygium occurs when the conjunctiva, the tissue that lies over the white of the eye, grows into the cornea. A pingueculum is a yellowish bump of tissue on the white of the eye.

Sunlight that bounces off highly reflective surfaces such as snow, water, sand, or pavement can be especially dangerous.

UV damage builds up over time. You generally don’t feel UV rays, so there is no natural warning that damage is being done. Although clouds reduce the level of UV reaching your eyes, clouds don’t block UV completely — which means your eyes can be exposed to UV rays even on overcast days.

 

There are three kinds of ultraviolet light:

  • UVA is lower in energy but penetrates more deeply than UVB.
  • UVB is a high-energy ray that causes the most damage to eyes.
  • UVC is the most powerful form of all.

Sunglasses play a vital role in shielding the fragile tissue around the eye.Most sunglasses block some UV so they can claim “UV protection” but Oakley’s lens materials filter out 100% of all UVA, UVB and UVC. The protection is built into the lens material so it can’t scratch off and leave your dilated pupils exposed to a UV leak. Oakley produce not only general purpose sunglasses for every day protection but road, grass, trail, water and snow specific lenses to optimise your vision in all sporting conditions. You can also have the best sun lenses custom made to your prescription.
