Why do climbers wear sunglasses?
1. In order to block the direct sunlight and protect our fragile eyes.
As we all know, with the increase of altitude, there are fewer and fewer substances in the air that can block sunlight, and the blocking of ultraviolet rays is getting weaker and weaker. When we are exposed to the sun, ultraviolet rays will directly harm our eyes. Our eyes are very fragile and sensitive and can't stand long-term ultraviolet radiation. After long-term irradiation, our eyes are likely to have cataracts, tears and eye pain.
2. In order to avoid the reflection of sunlight and other substances, it will cause irritating damage to the eyes.
On the way to climb the mountain, the line of sight is very important. Once you can't see clearly, it's very dangerous, and it is likely to pose a life threat to yourself. On the high mountain, the snow has been thick for many years. Coupled with the snowstorm, some snow is already slippery. So when the sun shines on the snow, it is easy to reflect light, and the light is very strong, which makes you dizzy easily. If you don't take protective measures, your eyes are likely to be affected by reflected light, which will affect your climbing progress and your safety.
Therefore, climbers wear sunglasses not to show how handsome they are, but to protect their eyes and absorb harmful light such as ultraviolet rays and infrared lamps. Let yourself be in the process of climbing without danger, so that you can enjoy the fun of climbing instead of being scared. It is also a symbol of professionalism. After all, climbers are well equipped. In a word, it is to ensure your own safety and enjoy climbing.
