1. Sports glasses introduction:
Sports glasses refer to the safety glasses worn in sports. Usually, advanced equipment has safety (PC lenses), protection (TR-90 frame, soft and flexible), comfort (non-slip nose pad and foot cover), and appearance (fitting). Sports, casual clothing with) the effect.
2. Sports eye composition and materials and performance:
A. lens
The PC lens is a space lens, which is a non-broken lens with 100% security. It is the thinnest lens in the world. It is 57% lighter than a glass lens, 37% lighter than a resin lens, and 26% thinner. At present, the world’s most impact-resistant lenses are first used in space shuttle observation windows and bullet-proof glass. Its impact resistance is 60 times that of glass sheets, 10 times that of ordinary safety resin sheets, and 100% UV resistance (UV400).
Magnesium alloy lens, its texture is light, 2/5 of titanium, 2/3 of aluminum, machining accuracy error of only 0.02mm, bright color, not fade, can add different colors to the lens, for environmental protection products. Benefits: There is a grade, light and comfortable to wear.
Polarized lenses use the principle of polarization (that is, the principle of blinds) and can act as a filter for stray light. It can filter harmful ultraviolet rays by 100%, and it can automatically adjust and block the strong reflected light that can not be blocked by general sports glasses, and adjusts all the light rays projected into the same direction light, eliminates the glare of reflected light and scattered light, and makes the eyes Under the sun to see the scene more clearly, have a better line of sight. Suitable for outdoor sports, driving, fishing, snow-capped mountains and other outdoor sports. Polaroid Corporation is the inventor of polarized lenses.
B. Frame
The TR-90 frame is a super-rigid resin material that is smooth, flexible, lightweight, 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 (CA), memory function, anti-deformation index of 620KG/CM2, 30% lighter than CA .
3. Purchase of sports glasses
Due to the variety of outdoor sports, including extreme cycling, outdoor mountaineering, jogging, skiing, golf, camping and other sports, the function requirements of sports glasses are different for different sports.
For those who engage in intense extreme sports, sports safety goggles should be equipped with safety (PC lenses), protection (TR-90 frame), comfort (non-slip nose pad and foot cover), beautiful (with sports, casual wear matching The effect of Windproof mirrors are suitable for long-term exercise in the outside world, especially for enthusiasts in areas with strong sandstorms. In order to meet the needs of myopic sports enthusiasts, the birth of myopic sports glasses has brought them more gospel. The function of myopic glasses not only includes the performance of ordinary glasses, but also uses a PC material to resist the impact of the surface, so that myopia friends can enjoy the fun of the sport. There is a long-term exposure to the sun, strong and prolonged exposure to sunlight, you need to buy polarized sports glasses.
For mountaineers, the snow on the mountains is easy to damage the eyes. In terms of ultraviolet rays, the reflected light of 10,000 feet of snow is more than 50 times above the seashore. The naked eye's retina is easily damaged, causing great pain called snow blindness, sunglasses can be reduced This damage, but not to be deceived by cloudy weather, because the ultraviolet rays will penetrate the clouds, the glare of light can cause headaches, sports glasses will have a filter effect of 95-100.
Glacial movements for glaciers require a penetration of 5-10, while multipurpose sports glasses must have a penetration of 20. When you look in the mirror at the time of purchase, if you can easily see your own eyes it is too bright. The color of the lenses is grey or green - if you want to see the real colors, if you want cloudy or thick fog, you want to look carefully. Choose yellow lenses, for infrared, unless you face the sun will be directly damaged, but the general sports glasses can prevent infrared penetration and protect the eyes, sports glasses must have side protection device to reduce the sun through the eyes, but Must have good ventilation to prevent lens fogging, or use anti-fog lenses or anti-fog cleaners, you need to bring a pair of spare sports glasses to avoid losing or use cardboard or clothes cut into thin strips covering the eyes. Most climbers prefer to use contact lenses because the glasses slide over the bridge of the nose to improve visual acuity without spots of water. However, there are still disadvantages. For example, the sun is too full, wind and sand can cause eye irritation. The countryside is not easy to clean and maintain.
From a professional point of view, when selecting sports glasses, people should pay attention to the lens function. Because different lenses have different filtering effects on light, they can adapt to different sports environments. Dark-colored lenses are better than light-colored lenses, which can effectively block UV rays and increase UV index. For example, purple lenses can reduce the visibility of visible light without affecting the visual clarity. Therefore, the lenses of the bicycle sports glasses can be purple and suitable for long wearing.
Gray lenses provide the best perception of color vision and are recommended by experts. The yellow lens can enhance the contrast in fog and it is recommended not to wear it when driving. The yellow-green progressive color and the purple gold-plated mercury lens can effectively filter the blue light and enhance the contrast between the sky and the ground. Therefore, the golf glasses use yellow-green and purple lenses to make the sphere more distinct in the field of vision. Every day, the sun continuously emits three kinds of light waves of ultraviolet rays, visible rays, and infrared rays. If there is no proper protection of glasses, each one will cause serious damage to the eyes and influence. Visible to choose a suitable sunglasses for their own sports requirements, color is very important. In addition, it is best to buy radiation-proof glasses that are resistant to UVA and UVB.
In the choice of the shape of the sports glasses, each person is also good for each, different face shapes have different requirements for different shapes of the frame. Remember the principle of complementarity—round-edged formulae and square-faced ellipses. Specifically: square face: large pilot-style glasses can be modified prominent chin line; round face: suitable for the frame is slightly thicker, the lens color is colder, darker color glasses, shrinking face visual effects. Long face: Should choose flat round or curved lens, slender proportion, visually give a sense of coordination. Cat glasses frame is the best choice; melon face: suitable for all kinds of shapes of sunglasses, choose more than enough to make you full of emotions. Small face is suitable for wearing thin frame or frameless glasses, choose elegant lenses will have unexpected results.
Frame selection requires flexibility, elasticity, impact resistance, and safety protection for the face during sports. The veneer design of the frame allows the eyes to cling to the edge of the frame to prevent irritation to the eyes from strong winds during rapid movement.
4. Sports eye protection
â—† Avoid contact with chemicals, such as perfumes and insecticides, to avoid chemical corrosion on the lenses and frames to better protect your glasses.

â—† Adhere to both hands and wear glasses. If you use too much force when you pick one hand, it may cause deformation and fracture of the frame.
â—† Avoid sports glasses for a long time under high temperature conditions, and do not soak the sports glasses in water for a long time;
