Vision at risk on winter slopes

Researchers in Spain have warned that one in five people taking part in winter sports could be risking sight problems.

The results have been published as part of the promotion for the Madrid Optical Fair ExpoOptica and it is claimed winter sports eyewear is vital to ward off eye damage.

The study, carried out by the Ophthalmologic Institute of Alicante, shows that as well as UV radiation from the sun, micro snow particles are also responsible for eye damage.

It says the action of the wind, snow, cold and mist causes the cornea to be lashed with microcrystals, resulting in serious damage to the eye.

This damage, known as snow ophthalmia, is exacerbated by altitude and causes inflammation of the cornea. This damage is often only apparent some hours after the winter sport has taken place and can lead to discomfort and visual disturbance.

The report also endorsed the greater need of protection for children against the effects of UV radiation because of the translucence of the lens in children.

The organisers of ExpoOptica use the report to point out that a wide range of frame and goggle options to protect against snow damage will be on display at the exhibition which takes place from March 10-12 at the Feria de Madrid.
