With the development of science and technology, skiing lenses have also evolved from single-layer to double-layer, from anti fog to anti fog, and can be used in various weather conditions. Plastic products are safer for the frame, and yellow or brown lenses are preferred. Ski goggles should have the following functions:
Firstly, prevent cold air from irritating the eyes;
Secondly, prevent UV rays from causing burns to the eyes;
Thirdly, the inner lens should not fog;
Fourthly, ski goggles should not cause facial injury after falling. (Note: Skiers wearing glasses should choose OTG ski goggles (Over The Glasses) to fully cover their nearsightedness.)
Fifthly, the impact resistance of lenses must pass the DROP BALL TEST and impact resistance tests according to international standards.
