How do Eskimos protect their eyes?
Generations of snow-bound Arctic Circle people, including the Inuit, have been protecting their eyes from snow blindness for over 4,000 years with snow goggles.
How did Eskimos prevent snow blindness?
Thousands of years ago, the Inuit and Yupik people of Alaska and northern Canada carved narrow slits into ivory, antler, and wood to create the world’s first snow goggles. This diminished exposure to direct and reflected ultraviolet rays—thereby reducing eye strain and preventing snow blindness.

Sunglasses are also lighter weight than goggles, and they can be fitted with your prescription.
Is it OK to ski without goggles?
Googles are also important for eye safety. If you were to ski without goggles, you risk harming your eyes and even potentially forming snow blindness. Your eyes are fragile and it doesn’t take much to cause damage, especially at high speeds. In that way, goggles are almost like helmets for your eyes.
What are snow goggles for?
Goggles are an essential part of skiing or snowboarding gear to protect your eyes from the elements and injury. Goggles protect your eyes from airborne snow and debris and shield them from hazards such as tree limbs and fallen branches. Ski goggles also stay securely on your head at times when sunglasses would fly off.
