The anti-fog function of the magnetic ski goggles

Multiple lenses help reduce fog of magnetic ski goggles. Also, make sure the lens has been treated with anti-fog reagents. Another way to prevent fog is to ventilate. Many goggles have vents at the top and bottom of the lenses. It allows fresh air to circulate, reduces fog formation, and provides fresh air for your eyes. The bigger the hole, the better the ventilation. However, the bigger the hole, the colder it gets. Many goggles have multiple lenses. Multi-lens goggles fog more slowly than single-lens goggles. Therefore, you'd better buy a pair of multi-lens goggles. Double - layer ski goggles with air holes are best for preventing fog.
