To protect eyes and face, ski goggles are designed to be large, covering most of the upper portion of the face and fitting snugly around the eye area. This style can protect wearers against wind, snow and ice. The large enough lens area can provide a wide field of view and good peripheral vision.
Most ski goggles are manufactured from materials such as nylon, rubber and propionate. These materials are softer and more flexible than those materials used in other eyeglasses and sunglasses. The main reason of using these materials is that they can hold their shape, do not become brittle in the cold and won’t injury the face when the wearer fall or hit some objects during skiing.
Most goggle styles are linked with a thick strap to ensure eye protection. Though some ski goggles look more like the regular sunglasses than athletic eyewear, there are also some differences between them. For example, ski goggle frames often have side shields to prevent wind and snow from entering the eyes. They also have cable, wraparound and temples to keep the frames stable.
The most usual choice of ski goggle lens color is yellow-orange hue. Through blocking out the blue, this color can enhance the contrast between objects and snow. In addition, rose is another good choice for skiers.
Polarized lenses are suitable for traditional sunglasses and eyeglasses because of glare reduction. However, this kind of lenses is not right for ski, because the lenses can reduce the sunshine and make the wearer to be unable to see the ice which should be avoided.
Ski goggles with large, one-piece constructions can be worn alone by people who wear contact lenses or don’t ask for vision correction. Of course, there are some prescription lenses which can be inserted to ski goggles to meet special requirements.
In addition, there are some tips of ski goggles buying. Firstly, people should purchase ski goggles with enough preparation. Secondly, people should buy the lenses which can provide 100 percent UV protection. Thirdly, ski goggles with features such as double lenses, anti-fog coating and wide vents are better.
