Why wear ski goggles when skiing? Usually do not pay attention to skiing people see this problem may first think of the role of eye protection, more general. In fact, the most useful function of ski goggles is to prevent people from getting snow blindness.

Snow blindness is inflammation caused by UV damage to the cornea and conjunctival epithelium of the eye. Characterized by eyelid swelling, conjunctiva congestion edema, intense foreign body sensation and pain, symptoms are afraid of light, tears and can not open eyes, there will be blurred vision during the disease.

   Why do you get snow blindness when you're skiing, when your eyes are looking straight ahead and you're not looking at the sun? Because the white snow reflects the sun's rays and UV rays to the greatest extent, the surrounding snow terrain will reflect UV rays from all angles to your eyeballs, which is unavoidable. This is where ski goggles come in.

  In addition to preventing snow blindness, ski goggles also prevent eye irritation from cold winds. In winter, when riding at a fast speed, people tend to feel sore eyes and can't stop crying. The same is true when skiing. The strong cold wind accompanied by high-speed sports will make the eyes sour and painful, which will hurt the eyes and affect the safety of skiing.

From the above two aspects, it is not difficult to get the function of ski goggles:

  Uv protection performance is better.
  Good sealing, can not fill wind.
  Anti-fog inside the mirror (anti-fog coating, set loose air holes).
  The eye contact area should be soft to prevent the ski goggles from damaging the face when you fall.
  To be friendly to myopic people, that is, ski goggles should be matched with myopic lenses.
  Ergonomic and comfortable to wear.
