With the rise of healthy living slogans, people use outdoor exercise in their spare time to stay healthy. So outdoor safety issues cannot be ignored. Therefore, while enjoying the process of exercise, you must also protect yourself. It is said that the eyes are the window to the soul, and it is also a signal tower during exercise. So how to choose sports glasses and other related issues must be carefully understood.
First, the introduction of sports glasses
Sports glasses refer to safety glasses worn in sports. Usually, advanced equipment has safety (PC lenses), protection (TR-90 frame, soft and flexible), comfortable (non-slip nose pads and foot covers), and beautiful (matching sports and casual clothing).
Second, the structure of sports glasses
1. Lens
1) PC lens is a space lens, which is a kind of lens that does not break or crack, and is 100% safe. It is currently the thinnest lens in the world, 57% lighter than glass lens, 37% lighter than resin lens, and 26% thinner. 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% 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. Different colors can be added to the lens, which is an environmentally friendly product. Advantages: It is classy to wear, light and comfortable.
3) The polarized lens adopts the principle of polarization (that is, the principle of blinds), which can play the role of filtering stray light. In addition to 100% filtering of harmful ultraviolet rays, it can automatically adjust and block the strong reflected light that cannot be blocked by general sports glasses, adjust all the projected light into the same direction light, eliminate dazzling reflected light and scattered light, and make the eyes more comfortable. The scenery is clearer and has a better line of sight under the sun. It is suitable for outdoor sports such as wild travel, driving, fishing, snow mountain climbing, etc. Polaroid is the inventor of polarized lenses.
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% lighter than CA .
Third, the characteristics of good sports glasses
1. The color of the left and right lenses is uniform and the difference is not more than 5%;
2. 100% resistant to ultraviolet rays; no deformation when viewing objects;
3. Comfortable to wear, will not beat or even fall off with the running rhythm;
4. The lens is not easy to be broken, and the frame has good toughness.
Fourth, the purchase direction of glasses for different sports
1. The lens must be selected well, because different lenses have different filtering effects on light and adapt to different environments. In terms of color, dark lenses are much better than light-colored lenses, can isolate more ultraviolet rays, and also Can improve the uv index. Specifically, it can be distinguished according to the corresponding sports:
(1) For less strenuous sports such as mountaineering and running, light gray, gray and light orange lenses can be used.
(2) For activities such as stream fishing, sea fishing, swimming, sailing, yachting, motorcycles, and cycling, light gray, brown, blue, and purple lenses can be used.
(3) For tennis, golf, shooting, archery, hunting, baseball, and driving, which require eyesight, brown, orange, light red, and light orange lenses can be used.
2. The material of the frame should be soft and flexible, resistant to impact, and at least protect the eyes during intense exercise. If possible, try to choose a veneer design, which can keep the eyes close to the edge of the frame and prevent strong wind from affecting the glasses. Impact.
Five, the protection of sports glasses
1. Avoid contact with perfumes, pesticides and other chemical-containing items to avoid chemical corrosion to lenses and frames and better protect your glasses;
2. After use, please wipe your sports glasses, put them in the glasses bag and store them properly. Do not store them with hard objects or sharp objects, so as not to scratch the lenses or the finish;
3. Please wipe with a professional glasses wipe before use, and rinse with professional cleaner if necessary; special attention: glasses with polarized lenses cannot be cleaned with ultrasonic waves and water, otherwise the polarized effect will be destroyed;
4. Sports glasses will inevitably have scratches and dark spots after long-term use. If the above situation occurs, it is recommended that you replace the glasses or lenses in time to protect your eyes; if you need to replace the lenses, please go to professional glasses for matching or directly Contact the manufacturer.
For sports enthusiasts, it is very worthwhile to enjoy the happiness brought by sports, but they also need to pay attention to their own safety, and choose professional sports glasses reasonably to wear them. Wouldn’t it be better to exercise in a safe state.
