Sunglasses have become the new fashion darling. Do you know how to choose sunglasses?

When choosing sunglasses, it is recommended to choose sunglasses with a UV value of more than 400. If the UV value is not marked on the sunglasses, it is best not to buy it. Look at the color of sunglasses are different, the protective effect on the eyes is also different. Generally speaking, dark sunglasses are more resistant to ultraviolet light than light-colored sunglasses. Yellow and brown sunglasses can enhance the recognition of certain colors and are suitable for use on cloudy or rainy days.

Oval faces avoid slender frames with oval faces that are supposed to be versatile (many stars have this face), but slender sunglasses make the face look longer. The best choice is a frame slightly wider than the face, so that the best visual ratio can be achieved. Triangular face bogey small round frame triangular face forehead narrow chin width, people feel that the face is very large. If you bring a narrow small round frame, your face will be wider.

Should go to the regular glasses shop to choose the sunglasses produced by regular manufacturers with anti-UV function. The glasses sold by street stalls and hawkers often fail to meet the UV protection standards, so it is best not to buy them. When choosing, pay attention to the surface of the lens to be smooth, no ripples, no defects, no bubbles, no wear marks. To place the lens flat, observe whether the lens is warped or not from the horizontal direction. Lenses that are uneven or have traces or bubbles are not suitable for purchase.

First, select the category according to the purpose. For example, to drive a car or travel, fishing, in short, it is used in places with complex light. Then choose polarized sunglasses. The lenses of these sunglasses are special and can filter harmful light and glare from the air. Secondly, choose according to the shape of the face and skin color. Once you have identified the categories you need, let's pick the style.

Westerners have deeper facial features than we easterners, and their faces are angular and angular. The frame materials of some big foreign brands are relatively thick, which are more suitable for the facial contours of westerners, but not for our oriental faces, so when choosing sunglasses, it is best to choose the ones that suit us, and don't blindly pursue luxury brands.

The color of sunglasses has something to do with not only their own collocation, but also the weather and occasions. Generally speaking, black / gray, brown / brown and green are the most widely applicable, while other colors are slightly limited. In addition, the color of the lens will not affect the UV protection ability of the lens. It is recommended that when shopping, try to look at the sunglasses with more optional colors, so that you can make a comparison.

How to choose sunglasses? Misunderstandings in the selection of sunglasses

2, misunderstanding 1: the darker the sunglasses, the better. I believe that many people will mistakenly think that the darker the sunglasses are, the more sunlight can be filtered out. But in fact, whether ordinary glasses and sunglasses, the original intention of their design is to consider the light transmittance of glasses, sunglasses should consider more optical structure. If the pure black sunglasses do not have a reasonable optical structure and drive rashly, there will be hidden dangers in traffic safety.

Have you won these misunderstandings? Myth 1: the darker the lens color, the more eye protection experts: the darker the color, the greater the damage to the eyes.

First of all, we should pay attention to whether sunglasses are really UV-proof. Now there are sales of sunglasses online and offline, some prices are ridiculously high, and some prices are horribly low. But if you wear inferior sunglasses that can't block ultraviolet rays, more ultraviolet rays enter your eyes than when you don't wear sunglasses, which is more likely to cause eye damage. Regular eye sellers have equipment to test the UV protection of sunglasses.

For example, if the degree is more than 800 degrees, it is not recommended to wear myopic sunglasses, because the glasses of patients with high degrees are too thick, after treatment, they are neither beautiful nor comfortable, and patients with high myopia are likely to be accompanied by amblyopia.
