Why do people wear sunglasses?

Below, the cloud mirror tells you why you need to wear sunglasses.

Basically everyone has sunglasses, today I will talk about sunglasses, I found that some people wear them, some people don't wear them, so in the end, is it good to wear them in summer, is it necessary to wear sunglasses? Here the mirror Xiaoer can definitely tell everyone that sunglasses must be worn, especially when the sun is strong, this is not only for beauty, decoration, wearing sunglasses has many benefits.

This is because one of the main functions of sunglasses is to block strong light and prevent harmful rays such as ultraviolet rays from entering the human eye too much and causing damage.

If you wear sunglasses in summer, firstly, it can reduce the adjustment burden of the ciliary muscles of the eyes under strong light, so that the eyes can see objects under the habitual natural light, which is the most comfortable time for the human eye, and second: wearing sunglasses is not only to block harmful light, but also, in windy weather, it can also prevent dust particles from entering people's eyes, which to a certain extent, it has become the best haven for the eyes.

The above is what Jing Xiaoer shared with you, hope.

The main function of wearing sunglasses is to prevent ultraviolet rays, too much ultraviolet radiation will harden our lens and become cloudy, which is commonly known as cataracts, and polarized sunglasses can filter out the glare on the surface of objects, and drivers can drive safer under strong light, and they can also play a good decorative role.

Summer is here, and sunglasses shield us from the scorching sun while adding points to our fashion. However, many people don't know the right way to wear sunglasses and whether they are suitable for them. Do you really wear sunglasses?

Who is not allowed to wear sunglasses? Tell you a few small mistakes about sunglasses.

Sunglasses are worn correctly and have a UV protection logo.

UV protection is the primary function of sunglasses, and some sunglasses have logos such as "100% UV protection", "UV400", "UV protection" on the lenses or packaging. If you wear low-quality sunglasses that do not block ultraviolet rays, more ultraviolet rays enter your eyes than if you do not wear sunglasses, which is more likely to cause eye damage, and over time, it can cause cataracts, and symptoms such as eye pain, corneal edema, and corneal epithelial detachment will occur. Regular optical stores generally have instruments to test the UV protection ability of sunglasses, which can detect whether you have made the right choice.

The spectacle lenses of street stalls and vendors are often of substandard quality, so it is best not to buy them.

Choose grey brown and green lenses.

The color of the lens should be selected in such a way that the color of the surrounding environment is not distorted, the edges of the object are clear, and the signal lights of different colors can be effectively recognized. The color of the lens is better in gray, brown and green, because these colors of the lens absorb infrared and ultraviolet rays better.

For some people with eye diseases, it is not suitable to wear sunglasses because there is a high chance of further damage to the eyes.

People who are not suitable for wearing sunglasses are: patients with angle-closure glaucoma who are suspected of inducing glaucoma, people with color blindness who have difficulty distinguishing colors, and people with high myopia who are protected against accidental attacks.

Not suitable for myopia. I have very high myopia in my eyes, and if I wear sunglasses, I can't see clearly.

People with big faces are not suitable, and people with big faces look out of place when they wear sunglasses, and they don't look good.

For example, some people with color weakness are not suitable, or some people with high myopia, it will be very inconvenient for them to wear sunglasses.

I think that people who are nearsighted and often wear glasses are not suitable for wearing sunglasses, and such people often wear glasses, and if they wear sunglasses again, it will be very uncomfortable.

People with color blindness, as well as younger children, have some eye problems, none of which are suitable, and sunglasses are to block the sun.

People with too big faces, people with low nose bridges. Not very suitable for wearing sunglasses. Because it doesn't highlight any beauty.

If you think that sunglasses are suitable for anyone, they are not suitable for people who are short-sighted, because you can only wear one glasses, and if you bring sunglasses, you may not be able to see the road there, and if you wear glasses, then you may not be able to wear sunglasses.
