At present, it is the most impact-resistant lens in the world. Its material is first used in space shuttle viewing windows and bulletproof glass. The impact resistance is 60 times that of glass sheets, 10 times that of ordinary safety resin sheets, and 100 percent anti-ultraviolet (UV400).
2) Magnesium alloy lenses are light in texture, 2/5 of titanium and 2/3 of aluminum. The machining accuracy error is only 0.02mm. The color is bright and not easy to fade. You can add different lenses to the lens. color, for eco-friendly products. Advantages: It is classy to wear, light and comfortable.
3) Polarized lens It adopts the principle of polarization (that is, the principle of blinds), which can play the role of filtering stray light.

2. Frame
The TR-90 frame is made of super tough resin material, which is smooth, flexible, light and comfortable to wear. It is characterized by high temperature resistance, instant high temperature resistance of 350 degrees, not easy to melt and burn, impact resistance is more than 2 times that of cellulose acetate plastic (CA), memory function, anti-deformation index reaches 620KG/CM2, and the weight is 30 percent lighter than CA .
Sports glasses purchase
1. The functions of glasses are different
Due to the There are various kinds of sports, including extreme cycling, outdoor mountaineering, jogging, skiing, golf, camping and other sports. Therefore, for different sports, the functional requirements of sports glasses are also different.

There is also the need to buy polarized sports glasses for long-term exposure to sunlight, strong and long-term sunlight sports. For mountaineering enthusiasts, the snow on the mountains can easily damage the eyes.

Sunglasses
can reduce This damage, but don’t be fooled by cloudy weather, because UV rays penetrate the clouds, harsh light can cause headaches, and sports glasses have a 95-100 filter effect. Sports glasses for glaciers need to have a penetration rate of 5-10, while multi-purpose sports glasses must have a penetration rate of 20.
2. Choice of color and frame
When buying, look in the mirror. If you can easily see your eyes, it is too bright.

Most rock climbers prefer to use contact lenses, because the glasses slide on the bridge of the nose, improve visual acuity, and prevent water spots, but there are still disadvantages, such as too much sun, wind, sand, dirt can cause eye inflammation, and at the same time The suburbs are not easy to clean and maintain.
From a professional point of view, when choosing sports glasses, people should pay attention to the lens function. Because different lenses have different filtering effects on light, they are suitable for different sports environments.
Dark lenses are better than light lenses, which can effectively block ultraviolet rays and improve the UV index. For example, purple lenses can reduce the degree of visible light entering the eye without affecting the clarity of vision. Therefore, the lenses of cycling sports glasses can be purple and suitable for long-term wear.
Grey lenses provide the best perception of color vision and are the type recommended by experts.
Yellow lenses, which can enhance contrast in foggy weather, are recommended not to wear while driving.
The yellow-green gradient and purple gold-plated mercury-plated lenses can effectively filter blue light and enhance the contrast between the sky and the ground, so golf glasses use yellow-green and purple lenses to make the sphere more distinct in the field of view.
