Therefore, while enjoying the process of exercise, you must also protect yourself. It is said that the eyes are the windows of the soul, and the signal tower during exercise. So how to choose sports glasses and other related issues must be carefully understood.
1. Introduction of sports glasses
Sports glasses refer to safety protective glasses worn during sports. Generally, advanced equipment has safety (PC lenses), protection (TR-90 frame, soft and flexible), comfort (non-slip nose pads and foot covers), and beautiful (matching The effect of sports and leisure clothing collocation).
Second, the structure of sports glasses
1. Lenses
1) PC lens is a space lens, it is a kind of lens that does not break or split, and the safety is 100%. It is currently the world's thinnest lens, 57% lighter than glass lens, 37% lighter than resin lens, and 26% thinner. It is currently the world's most impact-resistant lens. Its material is first used in space shuttle viewing windows and bulletproof glass. The impact resistance is 60 times that of glass sheets and 10 times that of ordinary safety resin sheets. It is 100% UV resistant (UV400).
2) Magnesium alloy lens, its texture is light, 2/5 of titanium, 2/3 of aluminum, processing accuracy error is only 0.02mm, bright color, not easy to fade, you can add different colors to the lens, it is an environmentally friendly product. Benefits: It is classy, light and comfortable to wear.
3) The polarized lens adopts the principle of polarization (that is, the principle of blinds), which can filter stray light. In addition to 100% filtering of harmful ultraviolet rays, it can also automatically adjust and block strong reflected light that cannot be blocked by general sports glasses, adjust all projected light into the same direction, eliminate dazzling reflected light, scattered light, and make eyes Seeing the scene in the sun is clearer and has a better line of sight. It is suitable for outdoor sports such as wild travel, driving, fishing, climbing snow mountain and so on. Polaroid is the inventor of polarized lenses.
2. Mirror frame
The TR-90 frame is made of super tough resin material, which is smooth, flexible and light, and comfortable to wear. It is characterized by high temperature resistance, instant resistance to 350 degrees high temperature, not easy to melt and burn, impact resistance is more than 2 times that of cellulose acetate plastic (CA), memory function, anti-deformation index up to 620KG/CM2, weight 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% resistance to ultraviolet rays; no deformation when viewing objects;
3. It is comfortable to wear and will not jump or even fall off following the running rhythm;
4. The lens is not easy to break, and the frame has good toughness.
Fourth, the direction of buying 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, darker lenses are much better than lighter ones, and can isolate more ultraviolet rays. Can increase the uv index. Specifically, it can be distinguished according to the corresponding sports:
(1) Light gray, gray, or light orange lenses can be used for sports such as mountaineering and running that are not too strenuous.
(2) For sports such as stream fishing, sea fishing, swimming, sailing, yachting, motorcycle, riding, etc., light gray, brown, blue, and purple lenses can be used.
(3) For sports such as tennis, golf, shooting, archery, hunting, baseball, and driving that emphasize eyesight requirements, brown, orange, light red, and light orange lenses can be used.
2. The material of the frame. The frame should be soft, flexible, resistant to impact, and at least protect the eyes during intense exercise. If possible, try to choose a veneer design to keep the eyes close to the edge of the frame and prevent strong winds from hitting the glasses. Impact.
Five, the protection of sports glasses
1. Avoid contact with perfumes, insecticides and other chemical-containing items to avoid chemical corrosion to the lenses and frames, and better protect your glasses;
2. After use, please wipe your sports glasses and put them in a glasses bag for proper storage. Do not store them with hard or sharp objects to avoid scratching the lenses or the finish;
3. Please wipe with professional glasses wiping cloth before use, if necessary, use professional cleaner to rinse; special attention: glasses with polarized lenses can not be cleaned with ultrasonic and water, otherwise the polarized effect will be destroyed;
4. Sports glasses will inevitably have abrasions and dark spots after long-term use. If the above conditions occur, 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 optician matching or directly Contact the manufacturer.
