The effect of sunglasses

First, it can reduce the adjustment burden of the ciliary muscles of the eyes under strong light, so that people can see objects under natural light, which is the most comfortable time for the human eyes.

Second, wearing sunglasses is not only to block harmful light, but also to prevent dust particles from entering people's eyes in windy weather, which is to some extent. According to experts' determination, since 1996, sunspot activities have become more and more frequent, which has caused more and more harm to human body by ultraviolet rays, especially in Qinghai, Tibet and other plateau areas in China, which are most vulnerable to ultraviolet rays because of the long sunshine time. Therefore, people living in these areas should especially wear sunglasses.

At the earliest, sunglasses had only one kind of big frame, the kind with big lenses. Because they looked like toad's eyes, people also called them frog glasses, which were round and had only one color. Now they are different. We have several kinds here, such as wide-edged, narrow-edged, square, round, long and biased, and there are many colors, red. On the contrary, I have no idea, but not all colors are good for my eyes. In addition, your favorite sunglasses are not necessarily suitable for you. Let's talk about the color of sunglasses first.

Different colors of sunglasses have different functions

Expert: From the physiological point of view, gray, green and brown are good for human eyes, but too deep and too shallow are not good. Sunglasses of different colors have different functions, so please choose the one that suits you.

Blue-gray: the absorption rate of visible light is the highest, and the visual effect is dark.

Mercury: high-density lens coating is suitable for outdoor sports.

yellow: it can improve the contrast and provide more accurate video, also called night vision goggles.

Gray film: It absorbs any spectrum evenly, so the viewing scene will only darken, but there will be no obvious color difference, showing a true and natural feeling.

dark brown film: improve visual contrast and clarity, and filter out a lot of blue light. In the case of serious air pollution or fog, the wearing effect is better.

Ray-Peng Green: While absorbing ultraviolet rays, maximize the green light reaching the eyes, which is suitable for people who are easily tired.

many people think that the darker the color of sunglasses lenses, the more UV-proof they are. In fact, whether sunglasses are UV-proof has nothing to do with the color depth of the mirror, but with the production materials of the lenses. If UV-proof materials are added in the production of sunglasses, they are sunglasses with UV-proof function. Such mirrors are usually sold with UV logo. However, due to the current processing technology, the UV-proof function of sunglasses can reach 97% at most, but not 1% at all. To judge whether sunglasses are UV-proof,

In addition to seeing whether they have UV logo, you can also see whether the frame edge of the lens is smooth. The lens with smooth edge is made of resin, which has strong UV-proof function. Generally, the lens with wavy edge is made of glass, which is not only poor in UV-proof function, but also easy to produce degrees during installation, which is harmful to our eyes.

How to choose sunglasses that suit you

1. Hangtag: In addition to telling you the manufacturer, trademark and place of origin of the glasses, the hangtag also hides a lot of useful information, such as whether the glasses you choose are sunglasses or light-colored glasses, resin lenses or other materials. Whether it is anti-ultraviolet and so on.

2. lens quality: one of the easiest ways to distinguish the quality of a lens is to shake the glasses back and forth in front of your eyes to see if the object moves with the lens.

3. Color: The selection of lens color should be based on the principle that the color of the surrounding environment is not distorted, the edge of the object is clear, and the signal lights with different colors can be effectively recognized.

4. UV index: For sunglasses, the UV index, that is, the effect of filtering ultraviolet rays, is a very important standard. At present, the UV index of most sunglasses is between 96% and 98%, and dark lenses are better than light lenses.

5. Frame: Choosing the right frame is also the guarantee for a pair of glasses to get good optical correction effect. Don't be too big or too heavy, and don't wear it for too long, otherwise you will easily fall into the sunglasses trap and wear some "sunglasses syndrome"

6. Lens materials: At present, the most common ones on the market are glass and resin. The disadvantage of glass lenses is that they are fragile and easy to stab the eyes. Compared with glass, resin lenses have the following advantages: not easy to break, light weight and high light transmittance. Therefore, the best choice is resin lens.

First of all, the best lens color system for sunglasses is light-colored lenses such as tan, gray and green, which has better visual effect and protective effect. Of course, if it's just for dressing up or matching, you can choose bright lens colors to highlight your charm.

tan: it is recognized as the best lens color in tan sunglasses products, which can absorb almost 1% ultraviolet and infrared rays; Moreover, the soft tone makes the vision comfortable and makes the eyes less tired.

Gray system: It can completely absorb infrared rays and most ultraviolet rays without changing the original color of the scene. Mild and natural colors are popular lens choices.

green glasses can absorb all infrared rays and 99% ultraviolet rays just like gray glasses, and blue and red in light can also be blocked, but sometimes the color of the scene will be changed after passing through green lenses. But because green brings people a cool and comfortable feeling and good eye protection, it is also the first choice for many friends.

yellow: yellow lenses can absorb 1% ultraviolet rays and most blue light. After absorbing blue light, the scenery you see will be clearer, so it is more common to wear yellow lenses as filters when hunting and shooting.

Red series: The sunglasses lenses with red series have better barrier property to some light with shorter wavelength, while the other protective effects are lower than the other three colors.
