One of the most important functions of sunglasses is to block the strong light and prevent harmful rays such as ultraviolet rays from entering human eyes too much and causing damage. If you wear sunglasses in the summer, you can reduce the adjustment burden of the ciliary muscles of the eyes under strong light, and let people see objects under the habit of natural light.

Wearing sunglasses is not only to block harmful light, at the same time, in windy weather, it can also prevent dust particles from entering people's eyes. To a certain extent, it has become the best haven for the eyes.

At present, the production materials of sunglasses lenses on the market are basically the same as myopia lenses, and they are also divided into two categories: glass and resin, but the processing technology of the two are different. Sunglasses with glass lenses are mainly mixed with some metal salts with special absorption properties in the glass material. For example, glass lenses with nickel and cobalt are purple, and glass lenses with cobalt and copper are blue.

Sunglasses with resin lenses mainly use the immersion dyeing method, in which the lenses are soaked in hot water dissolved inorganic pigments for coloring. But no matter what kind of coloring method, the color of sunglasses we choose must be good for our eyes, so in the face of so many colors of sunglasses on the market, we must clarify the role of the following different colors of sunglasses.

Blue-gray: the highest visible light absorption rate, the visual effect is darker.

Mercury: The use of high-density lens coating is suitable for outdoor sportspeople.

Yellow: Improve contrast and provide more accurate images, also known as night vision goggles.

Gray: It absorbs evenly on any spectrum, so the scene will only become dark when viewed, but there will be no obvious chromatic aberration, showing a real and natural feeling.

Tawny: It can improve visual contrast and clarity, filter out a lot of blue light. In the case of severe air pollution or fog, the wearing effect is better.

Ray-ban green: While absorbing ultraviolet rays, it maximizes the green light reaching the eyes and is suitable for people who are prone to fatigue.

Sunglasses with too dark colors are likely to cause traffic accidents due to poor traffic signal recognition capabilities, and sunglasses with too light colors will not be able to block the sun. You must try it out when you buy it to see the change in the color difference in the surrounding environment. Generally speaking, the color of sunglasses with small chromatic aberration is more appropriate.

Many people think that the darker the color of the sunglasses, the better the UV protection. In fact, the protection of sunglasses has nothing to do with the color of the lens, but the material of the lens. If sunglasses are produced with anti-ultraviolet materials, they are sunglasses with anti-ultraviolet functions. Such sunglasses are generally sold with a UV logo.

In addition to seeing whether it has a UV logo, you can also see whether the edge of the lens is smooth. The smooth edge is made of resin material. This kind of lens has a strong anti-ultraviolet function. The wave-shaped edge of the lens is generally glass. The material of the lens, this kind of lens is not only poor in anti-ultraviolet function but also easy to produce power when installed, which is harmful to our eyes.

From the perspective of human physiology, gray, green, and brown sunglasses are good for human eyes, too dark and too light colors of lenses are not good for eyes.
