Why do people always wear sunglasses in summer? Can they see the road clearly?

Of course, you can see the road clearly, and in the hot sun, you can see more clearly than people who don't wear sunglasses. Summer is coming, sunglasses are the best-selling season, which can be said to be a necessity for people. Some people even buy sunglasses with different colors and frames to match different clothes. Of course, sunglasses are not only used to match clothes, but also their biggest function is to protect eyes, because sunglasses can effectively isolate ultraviolet rays and avoid direct sunlight, so wearing sunglasses can not only see the road clearly but also protect eyes. Let's talk about the benefits of wearing sunglasses in summer

Avoid the damage of strong light to retina. The sunshine in summer is the most dazzling, and its light is also the most harmful to the eyes, because when our eyes are exposed to direct sunlight, then our iris will shrink and we can't help but squint. If the direct sunlight lasts longer, our eyes will be more painful, just like walking in the snow without sunglasses and being reflected by strong light. Therefore, when we travel in summer, we'd better wear sunglasses, which can help.

Sunglasses can effectively resist ultraviolet rays. In fact, ultraviolet rays are more harmful to our eyes than strong light. This is the same as applying sunscreen and sunscreen when we go out. Too strong ultraviolet rays will damage our skin, and too strong ultraviolet rays will also damage our eyes. Therefore, you must wear sunglasses when you go out in the hot sun to avoid ultraviolet rays burning our retina and cornea, causing inflammation and pain.

So based on these two points, it is really necessary to wear sunglasses in summer to protect our eyes. Secondly, you can see more clearly when you walk. After all, walking in the hot sun will make our eyes feel pain and soreness, and may even be blurred by the sun's light. If we wear sunglasses, this will not happen basically, but choosing sunglasses is also the key. You must choose the one that suits you and the lens is better, in order to play a role.
