Man UV400 Protection Classic Cycling Sunglasses can protect our glasses. In high altitude mountainous areas, the air is thin and there is little dust in the air. The ability to absorb and block sunlight will be weakened accordingly, so the sunlight here is particularly strong. In addition, thick snow accumulates on the slopes and peaks of high mountains, and white is the most reflective color. Even if you keep your head down and don't look at the sun, you can't hide from the dazzling sun. If the eye is not covered, strong infrared and ultraviolet radiation will burn the visual cells, and in serious cases, it will cause vision loss or even blindness. The sunglasses worn by mountaineers are different from ordinary sunglasses. They can not only block the visible light in the sun, but also contain chemicals that absorb infrared and ultraviolet rays, which can comprehensively protect athletes' eyes. Therefore, when climbing mountains, athletes must wear sunglasses to protect their eyes.
