How To Choose The Right Ski Goggles?
The snow environment where we ski is easy to cause snow blindness, and it is easy to hurt our eyes when we fall down during high-speed sports. In addition, the cold wind does great damage to our eyes during skiing, so we need appropriate ski goggles to protect our eyes.
Ski goggles are divided into mountain goggles, platform goggles, cross-country goggles, free goggles, etc. A good pair of ski glasses can do the following:
▲ Prevent cold wind damage to the eyes, the use of temperature should reach minus 30 degrees, the lens frame is not brittle crack.
▲ High quality mirror coating to prevent UV burns on the eyes, effectively filter the harmful light to glasses. While keeping the brightness and the view open.
▲ Air circulation design and anti-fog material to ensure that the mirror can not fog, ergonomic, do not shake. The length and width of the mirror band with good elasticity.
▲ The lens frame is made of soft and special materials, usually polycarbonate (a special plastic). The glasses only deform under the action of external force, and the external force should be quickly restored.
▲ After an accident, the glasses should not be hurt even if they are broken. In some areas there are standards for impact pressure.
Based on the above requirements, we should pay attention to the following points when choosing ski goggles:
01
Understand a sphere and a cylinder
The lens of ski mirror is divided into cylindrical mirror and spherical mirror. The cylindrical lens does not have radian in the vertical direction, which looks like the surface of the common column, which will cause more reflection, make the vision smaller, and even produce deformation; Because the spherical mirror is curved in both horizontal and vertical directions, it can increase the field of view, make the view wider and safer. At the same time, the curved plane can also reduce glare. The impact resistance and deformation resistance of the spherical mirror are better than those of the cylindrical lens.
02
Anti-fog performance
When skiing, lens fogging is a very dangerous thing. It is recommended to choose ski goggles with anti-fogging coating. Generally, only double-layer lenses can have anti-fogging function, because the inner layer is anti-fogging coating. Sometimes, such as blocking the ventilation passage, the anti-fog layer failure of the snow mirror after the best use time, also need to be adjusted in time.
03
Fit to the head/face shape
Based on the bridge of the nose and the shape of the face, the glasses are also divided into European and American versions and Asian versions. The Asian version is more in line with the overall facial structure of Asian people. Because the nose bridge of European and American people is generally cross-high and the skeleton is large, we will encounter air leakage when using the European and American version of ski goggles, or snow will be poured in during sliding, which is easy to cause fog. Therefore, if conditions are available, choose ski goggles to try on the spot as far as possible.
04
Lens color
Ski goggles come in different colors for different weather conditions.
Black snow mirror, more suitable for sunny weather, can effectively block strong light through;
Red/orange ski goggles are all-weather snow goggles, which can not only weaken the intensity of sunlight on sunny days, but also ensure a clear view when skiing on cloudy days and at night.
Pink ski goggles are also known as all-weather snow goggles, but will be slightly dazzling when the sun is shining, more suitable for overcast days and night skiing;
Transparent/yellow system, the contrast of yellow system is relatively strong, so you can clearly see the bump of the snow surface, than pink system is more suitable for bad weather and night skiing;
Silver-gray snow mirrors can see more clearly on sunny days than red-orange and pink ones.
Blue/green is also an all-weather snow mirror, which has higher contrast than yellow and can clearly distinguish the bumps and bumps on the snow surface, but it is not as clear as red-orange at dusk and night.
In short, we should try to choose a fully closed type of ski mirror, mirror frame with plastic products is relatively safe, can be close to the face, prevent the wind. The mirror is made of colored material coated with anti-fog and anti-ultraviolet coating. This material is very soft, twisted and deformed without breaking, so as to ensure that the mirror will not hurt the face when it is hit.
In addition, the upper edge of the outer frame is made of air permeability sponge, so that the heat discharged from the facial skin can be dispersed to the mirror, to ensure that the mirror has a good visual effect. Ski lens preferably double layer, anti fog coating, can be used in all weather conditions.
