Classification and color of sunglasses

In the scorching summer, we all know that we need to protect our skin from sun protection, but have you done a good job of protecting your eyes from sun protection? Tr90 Sunglasses, as a kind of sunshade glasses, are personal protection products. The main function is to prevent the stimulation and damage of human eyes caused by external ultraviolet rays and provide a comfortable viewing environment.

Dark color does not mean a strong UV protection function

It should be pointed out that there is no correlation between the shade of the lens and the protective effect of Tr90 Sunglasses. Not the darker the color, the stronger the UV protection function. Whether it can prevent ultraviolet rays mainly depends on the functional design of the lens itself, and the choice of color depth can vary from person to person. Outdoors with strong sunlight, you should choose a lens with a relatively darker color, and choose a lens with a lighter color when driving. Generally, dark gray is better, followed by dark brown and brown.

Classification of sunglasses

According to lens type, Tr90 Sunglasses can be divided into uniformly tinted sunglasses, gradient tinted sunglasses, and polarized sunglasses. Different groups of people can choose according to their preferences and uses, but the most basic principle is to protect the wearer's safety and vision from damage. Tr90 Sunglasses lenses come in a variety of colors, such as blue, pink, yellow, black, and gradient colors, which can be described as gorgeous colors. The reason why sunglasses can show different colors is mostly achieved through dyeing and painting. Dyeing refers to the addition of some chemical substances during the lens manufacturing process to make the lens appear colored to absorb light of a specific wavelength. This is the most commonly used method in sunglass making. Coloring refers to applying color to the surface of the lens, which can be applied uniformly or gradually. In addition, there is another way to change the color of the lens, which is to add silver halide to the lens, so that the originally transparent and colorless lens will become a colored lens after being exposed to strong light outdoors. If you buy sunglasses in shopping malls or online stores, you should pay attention to whether there are signs such as "100% UV protection" and "UV400" on the lens, tag, or outer packaging of the sunglasses.
