In the past two years, more and more people have chosen skiing as their hobby sport. In addition to skiing in northern cities in the snow season, many southern cities have indoor ski resorts. So now whether it is winter or summer, we You can do skiing.
At the same time, what kind of ski goggles to choose has now become a problem for many novices.
First of all, we must understand, why do we need to wear ski goggles when skiing?
The main function of ski goggles is to prevent "snow blindness", which is caused by inflammation caused by UV damage to the cornea and conjunctival epithelium.
Because the snow has a high reflectivity to sunlight, it can reach nearly 95%. Looking directly at the snow is like looking directly at the sun. In addition, the cold wind during sliding is very irritating to the eyes, so ski goggles are needed to protect the skiers. Eyes, and the ultraviolet rays in the sun are the culprit for snow blindness.
How to choose?
First, understand the spherical and cylindrical surfaces
The shape of the lens is basically divided into two categories, spherical and cylindrical. Most people choose cylindrical because cylindrical looks cooler, but in fact, the technical indicators of spherical lenses are better than cylindrical lenses.
Second, the optical technology of the lens
Different lenses have different treatment technologies for light. We need to understand its anti-ultraviolet and anti-blue light effect.
Third, vision
The field of view is also very important. One is the choice of lens color, because we will encounter sunny, cloudy and other weather conditions during skiing. Different weather needs to choose different colors of lenses to wear. The second is that a wider field of view allows you to see more clearly and avoid obstacles better.
Fourth, anti-fog
Anti-fog is also very important. It is recommended to choose ski goggles with anti-fog coating. General ski goggles made of single-layer lenses have no anti-fog function. Only double-layer lenses have anti-fog function, because the inner The layer is an anti-fog coating. Sometimes, such as blocking the ventilation channel, the anti-fog layer of the snow goggles after the best use time, etc., which need to be adjusted in time. Another point is that many novices don’t know that ski goggles are available in European and American versions and Asian versions. The Asian version is more in line with the overall structure of our Asian faces. Because Europeans and Americans have high nose bridges and large skeletons, we are in If you use the European and American version of the ski goggles, you will encounter air leakage, or snow will pour in during sliding, which will easily cause fogging.
I hope everyone, when choosing ski goggles, not only look at its high-value appearance, but also pay more attention to whether its functionality is suitable.
