Why is a ski sunglass important?
The first feature of your ski sunglasses is to effectively protect your eyes from the glare of the sun on the snow, a glare that can be fierce and aggressive to the eyes. And the higher you climb, the more damaging the UV radiation becomes. That's why the winter sun is just as dangerous as the summer sun or more. The damage caused by UV rays can be significant: snow ophthalmia, keratitis, cataracts, etc. And the sun in the snow quickly damages. It only takes 30 minutes to get corneal disease. Snow reflects up to 80% of the light rays against 20% at sea, and the glare increases by 10% every 1000 meters.
What is snow ophthalmia, a common disease? It is characterized by a foreign body sensation in the eye, burning sensation, mild discomfort and intense irritation. It can take up to 48 hours of total darkness. It is easy to avoid if you wear suitable glasses. And do not forget our children! The eyes of children are to be protected even more than those of adults, because they are more permeable. Before the age of ten, the children's eye lens transmits 75% of UV radiation. For this reason, it is important that they are equipped with a sunglass appropriate for the mountains.
