Ski goggles are glasses that are worn to protect the eyes while skiing. Ski goggles are required to protect the skier's eyes due to the strong reflection of sunlight on the snow and the stimulation of the eyes by the cold wind during sliding. It should be noted that skiers who wear glasses should opt for OTG (Over The Glasses) snow goggles to fully cover their myopia.

Function
Ski lenses have evolved from single layer to double layer, from non-fog to anti-fog, and can be used in a variety of weather conditions as science and technology have advanced. The frame is made of plastic, which is safer, and the lens is preferably yellow or brown in colour. The following features should be included in ski goggles:
First, keep cold wind from irritating your eyes; second, keep ultraviolet rays from burning your eyes.
Third, the inner lens is not foggable.
Fourth, ski goggles should not cause facial injuries after a fall. (Note: To fully cover myopia, skiers who wear glasses should choose OTG ski goggles (Over The Glasses).

Fifth, the impact resistance of the lens, the international standard must pass the drop ball test (DROP BALL TEST) and the impact resistance test.
