In the previous article, we discussed “Why should you wear polarized sunglasses?”. In this article, let’s talk about “Should you wear sunglasses in the winter?”.
Many people will ask this question. Do you need to wear sunglasses when the weather is so cold in winter? If you don't think it is necessary, then you are wrong. So, why wear sunglasses in winter?
The role of sunglasses
We need to know that the big role of wearing sunglasses is not to be handsome and cool, but to protect your eyes from UV rays. Because our eyeballs easily absorb ultraviolet rays, we must know that if the eyeballs are affected by ultraviolet rays, they will not be immediately visible, but will accumulate the damage bit by bit, which may cause the cornea and retina to gradually suffer. Damage and degeneration, and will make the lens cloudy and even cause cataracts, which will eventually lead to permanent vision damage. Ultraviolet rays come from the sun. Even though it is cloudy, ultraviolet rays are still present. So you need to wear sunglasses in winter. Otherwise, the damage of ultraviolet rays will accumulate invisibly.
Should I wear sunglasses in winter?
In summer, the light is strong, and the ultraviolet radiation is correspondingly strong. Most people will actively wear sunglasses. However, due to the low temperature in winter, most people don't wear sunglasses even when the sun is strong. But at this time, the ultraviolet rays have already harmed the eyes unknowingly. Although the sunlight in winter is not so dazzling, the ultraviolet rays in winter are just as strong. In addition, in winter, the temperature is low and the air is dry, and the penetration of ultraviolet rays is strengthened. Especially after it snows, the snow reflects sunlight, which increases the lethality of ultraviolet rays on the eyes. Therefore, you should wear sunglasses to protect your eyes in winter, and choose lenses with UV protection logos.
In winter, ultraviolet rays are more likely to enter the eyes?
In winter, the position of the sun is lower than in summer. Therefore, the sun's rays will more easily enter human eyes. While receiving a lot of sun rays with the naked eye, the eyes also receive a lot of harmful ultraviolet rays. Especially the sunlight reflected by chicken blood is even more dangerous to the eyes. The ultraviolet rays in the sunlight reflected by a large area of snowy roads can be as high as 90% or more. Before we knew it, or didn't realize it at all, dalde ultraviolet rays had already penetrated our precious eyes.
The ultraviolet rays in winter are indeed less than in summer, but there are still some. Many women have begun to pay attention to sun protection for the skin year-round, and at the same time do not neglect eye protection.
