The sun is shining and it's the perfect weather for a day's skiing, a real "dream day". But the nice weather also comes with a risk factor: the UV rays of the sun. Here you can find out how to deal with these and how you can best protect your eyes .
Why do ski goggles need UV protection
Sun protection also in winter? How come? Yes, even in winter the sun shines. This also allows harmful UV rays to get into your eyes. This solar radiation is even particularly high on the mountain because snow and ice reflect the sunlight. So you are actually exposed to twice the amount of sun on a day of skiing.
UV protection - ski goggles for your eye health
The retina of the eyes can perceive light waves with lengths of 390 to 780 nanometers. However, ultraviolet light, i.e. UV rays, is less than 390 nanometers long. Thus, we cannot see the light and therefore cannot properly assess the danger that accompanies it. The so-called UV-B rays are particularly dangerous. You probably already know their effects if you have ever had a sunburn. In the eye, if exposed too frequently, they can cause conjunctivitis and clouding of your eyes lens. It is therefore important that when choosing ski goggles you make sure that they protect your eyes from all UV rays (UV-A, UV-B and UV-C) .
UV rays – which ski goggles protect
When choosing your ski goggles on sunny days, you should pay attention to the VLT value . Here you can read what it says exactly. Roughly speaking, this value indicates how much sunlight enters your eye through the lens of a ski goggle. This is divided into categories (CAT.). So if there is a lot of sunshine, you should go for glasses in the CAT category. 3 or CAT. 4.
