How to choose a suitable pair of sunglasses for yourself？

Summer is the best time to choose sunglasses with gray lenses. Summer is here, and maybe everyone has sunglasses. Today, let’s talk about sunglasses. I found that some people wear them and some don’t. So, is it good to wear sunglasses in summer? Is it necessary to wear sunglasses? It can be confidently told that sunglasses must be worn, especially in strong sunlight. This is not just for beauty and decoration, wearing sunglasses has many benefits.

This is because the main function of sunglasses is to block strong light and prevent harmful rays such as ultraviolet rays from entering the human eye too much, causing harm. If you wear sunglasses in summer, firstly, it can reduce the adjustment burden on the ciliary muscle of the eyes under strong light, allowing the eyes to see objects under natural light, which is the most comfortable time for the eyes. Secondly, wearing sunglasses is not only to block harmful light, but also to prevent dust particles from entering the eyes in windy weather, which to some extent becomes the best shelter for the eyes. According to the determination of relevant experts, since 1996, sunspot activities have become more and more frequent, leading to more and more damage to human body caused by ultraviolet rays. Especially in Qinghai, Xizang and other plateau areas in China, where the sun shines for a long time, people are most vulnerable to ultraviolet rays. Therefore, people living in these areas should especially wear sunglasses.

At first, there was only one type of sunglasses with a large frame and large lenses, which looked like the two eyes of a toad, so people called them “toad glasses” at that time. They were round and had only one color, black. Nowadays, there are several types here, such as wide and narrow edges, square, round, long, and biased. There are also many colors, including red, green, yellow, and amber, which make people’s eyes dizzy. Now there are more than 20 options, and there is a lot of room for choice, but not all colors are good for the eyes. Also, wearing sunglasses that you like may not necessarily be suitable for you. Let’s talk about the colors of sunglasses first. Problem.

At present, the production materials of solar lenses on the market are basically the same as those of nearsighted lenses, which are divided into two categories: glass lenses and resin lenses. However, the processing technology of the two is different. Glass lenses are mainly made by mixing some metal salts with special absorption properties into the glass material. For example, glass lenses with nickel and cobalt added are purple, while glass lenses with cobalt and copper added are blue. Resin lenses mainly use immersion dyeing method, which immerses the lenses in hot water dissolved in organic pigments for coloring. However, no matter which coloring method is used, the color of sunglasses must be beneficial to our eyes. So, when facing so many colors of sunglasses on the market, which one should we choose?

Expert: From a physiological perspective, gray, green, and brown colors are good for the human eye, while too dark or too light colors are not good. Various types of sunglasses have different functions, please choose the one that suits you,

Blue gray: has the highest visible light absorption rate and a darker visual effect.

Mercury: High density lens coating is suitable for outdoor sports enthusiasts.

Yellow: Enhances contrast and provides more accurate images, also known as night vision goggles.

Gray film: It absorbs any spectrum evenly, so when viewing the scenery, it will only darken, but there will be no significant color difference, presenting a true and natural feeling.

Tea color film: improves visual contrast and clarity, filters out a large amount of blue light. Wearing it is more effective in cases of severe air pollution or foggy conditions.

Ray Ban Green: While absorbing ultraviolet light, it maximizes the amount of green light reaching the eyes, making it suitable for people who are prone to fatigue.

However, sunglasses with too dark colors are likely to cause traffic accidents due to poor traffic signal recognition ability, and sunglasses with too light colors cannot block sunlight. Currently, China only has strict regulations on the traffic signal recognition ability of red, green, and yellow sunglasses, and there are no relevant regulations for other colors. However, here is a trick you can try when choosing sunglasses: be sure to try them on when purchasing to see the size of the color difference changes in the surrounding environment. Sunglasses with small color difference changes are generally more suitable in color.

Many people believe that the darker the color of sunglasses lenses, the more UV resistant they are. In fact, whether sunglasses are UV resistant or not is not related to the depth of the mirror’s color, but to the production material of the lenses. If UV resistant materials are added to sunglasses during production, they are sunglasses with UV protection function. Such mirrors are usually sold with UV markings, but due to current processing technology limitations, the UV protection function of sunglasses can reach up to 97%, which is not 100% at all. Therefore, when you see sunglasses with UV 100% markings, it is actually a name that does not match reality; Determine whether sunglasses are UV resistant,
