The functions of the ski goggles

With the development of science and technology, the lens of ski goggles also developed from single guide to double layer, never anti-fog to anti-frost, can be applied to all kinds of weather conditions. The inner lens is made of resin material with good water absorbency. It has a good anti-fogging effect after being soaked in anti-fogging liquid. The surface of the outer lens is hardened to prevent the lens from being scratched. In addition, the upper edge of the outer frame is provided with an air vent made of a breathable sponge, so that the hot air discharged from the facial skin can be dispersed to the outside of the ski goggles to ensure a good visual effect
