How to choose a pair of sunglasses that is right for you

When choosing sunglasses, you need to go to a regular optical store, not sunglasses from street stalls.

The wearing of sunglasses is no longer just for aesthetics, we give it more meaning, it can prevent ultraviolet rays and better care for the eye skin. Then this requires us to be more rigorous in choosing sunglasses. Generally speaking, sunglasses from street stalls generally do not meet the standards of UV protection.

Therefore, it is recommended that you go to a regular optical store to buy sunglasses, sunglasses with anti-ultraviolet effect, so as to better care for the eye skin.

The lenses should be smooth and delicate, without flaws, bubbles, and abrasion marks, and should not be uneven and have bubbles.

When it comes to choosing sunglasses, the choice of lenses is even more crucial. Every detail needs to be carefully observed, and it is necessary to see whether the surface of the lens is delicate and smooth enough. The overall lens does not have ripples, no flaws, and no bubbles or even wear marks.

These small imperfections will affect the wearing of sunglasses, so when we choose sunglasses, we need to square the lenses. Look horizontally for curls or unevenness in the lenses. If the lenses have bulges, bubbles, or abrasion marks, don't choose them.

The color of the lens should be more realistic, not distorted, and the signal light of different colors can be accurately judged.

Sunglasses are colored, and after wearing different state colors, the color of the surrounding environment will be different. When we choose sunglasses, the color of the sunglasses should not be distorted, if the color you see deviates too much from the original color, or even the edges of the object are not clear, it will affect our overall ability to see things. When choosing sunglasses, we must be able to judge the different colors of the signal light as the principle, otherwise the sunglasses with eraser distortion will really affect our safety.

There's a simple and effective way to protect yourself from UV rays – wear sunglasses. So, how do you choose the right sunglasses for you?

Sunglasses that protect against UV rays have an identity – UV400, which means that they can filter light with wavelengths below 400nm. Sunglasses that can block ultraviolet rays are made through different manufacturing processes to block short-wavelength rays.

Tips. Many inexpensive sunglasses are only coated on the front of the lens, which only protects against the UV rays in front of them, and does not take into account the UV beam line reflected from other directions, such as the back of the lens.

It can also make the nose look shorter. If the nose is too small, you can choose sunglasses with light lenses and high nose pads. Visually, the nose will appear more elongated.

When choosing sunglasses, in addition to the appearance and appearance, the protection of the eyes is also very important, and you must pay attention to the following:

Myth 1: Wearing sunglasses can protect your eyes?

Many people think that wearing sunglasses will protect their eyes, but this is not the case. A good pair of sunglasses can not only block ultraviolet rays, but also be able to distinguish different colors of external signals, if wearing glasses, the world in front of you is a single color, such as not being able to distinguish traffic lights, which may cause safety hazards.

In addition, some low-quality sunglasses may have excess diopters, and people with normal vision wear them as if they were wearing a pair of myopia or reading glasses, resulting in affected vision. There are also some substandard sunglasses that block useful visible light, making the ultraviolet radiation more obvious, causing a series of ultraviolet eye diseases.

Myth 2: The darker the lens, the better?

Sunglasses are mainly used to prevent UV damage to the eyes, and preventing UV rays from entering the eye does not depend on the depth of color of the lenses, but is determined by the UV absorbers in the sunglasses material.

If you only choose tinted glasses that do not have UV protection, your eyes will still be damaged by UV rays.
