How to Choose Sports Glasses ?
First, the introduction of sports glasses
Sports glasses refers to the safety protective glasses worn in sports, usually advanced equipment with safety (PC lens), protection (TR-90 frame, soft and elastic), comfortable (non-slip nose pad and foot cover), beautiful (with sports, casual clothing matching) effect.
Second, the structure of sports glasses
1, the lens
1)PC lens is space slice, is a kind of non-broken lens, safety 100%.It is currently the world's thinest lens, 57% lighter than glass lens, 37% lighter than resin lens, 26% thinner, the world's most impact resistant lens, its material is first used in the space shuttle window and bulletproof glass, impact resistance is 60 times of glass, is 10 times of ordinary safe resin sheet, 100% UV400 resistance.
2) Magnesium alloy lens, its light texture, titanium 2/5, aluminum 2/3, processing accuracy error is only 0.02mm, bright color, not easy to fade, can be added to the lens with different colors, for environmental protection products.Advantages: It is classy, light and comfortable.
3) Polarized lenses use the principle of polarization (that is, the principle of blinds), which can filter stray light.In addition to 100% filtering harmful ultraviolet rays, it can automatically adjust and block the strong reflected light that can not be blocked by general sports glasses, adjust all the projected light into the same direction, eliminate dazzling reflected light and scattered light, so that the eyes can see the scene more clearly and have a better line of sight in the sun.Suitable for wild travel, driving, fishing, snow climbing and other outdoor sports.Polaroid was the inventor of the polarizing lens.
2, picture frame,
The TR-90 frame is made of ultra-tough resin material, which is smooth, flexible and light, and comfortable to wear.It is characterized by high temperature resistance, instantaneous resistance to 350 degrees high temperature, not easy to melt and burn, impact resistance is more than 2 times of cellulose acetate plastic (CA), memory function,
deformation resistance index up to 620KG/CM2, weight is 30% lighter than CA.
Three, the characteristics of good sports glasses
1. The color of the left and right lenses is uniform and the difference is no more than 5%;
2, can 100% resistance to UV;When viewing the object does not deform;
3. It is comfortable to wear, and will not jump or even fall off with the running rhythm;
4, the lens is not easy to break, the frame toughness is good.
Fourth, the direction of choosing glasses for different sports events
1, the lens must be a good choice, because different lenses on the light filtering effect is different, the environment is different, from the color of the dark lens is much better than the light lens, can isolate more ultraviolet, but also can improve the UV index.Specific can be distinguished according to the corresponding movement:
(1) Mountaineering, running and other such sports are not too intense sports, can use light gray, gray, pale orange lenses.
(2) River fishing, sea fishing, swimming, sailing, yacht, motorcycle, cycling and other sports, light gray, brown, blue and purple lenses can be selected.
(3) Tennis, golf, shooting, archery, hunting, baseball, driving these to emphasize the requirements of the eye, can use brown, orange, light red, pale orange lenses.
2, the frame of the material, the frame should also be soft and elastic, impact resistant, in the fierce movement at least can protect the eyes, if possible, try to choose veneer design, can make the eyes close to the edge of the frame, to prevent the impact of strong wind on the glasses.
Five, the protection of sports glasses
1. Avoid contact with perfume, insecticide and other chemicals to avoid chemical corrosion of lenses and frames and better protect your glasses;
2. After use, please wipe your sports glasses and put them in the eyewear bag for safe storage. Do not store them with hard objects or sharp objects to avoid scratching the lens or finish paint.
3. Before use, please wipe with professional glasses wiping cloth, and use professional detergent to rinse if necessary;Special attention: the glasses with polarized lenses can not be cleaned by ultrasonic wave 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 situation occurs, it is recommended that you replace your glasses or lenses in time to protect your eyes;If you need to replace the lens, please go to the professional matching glasses or contact the manufacturer directly.
For sports lovers, it is very worth doing to enjoy the happiness brought by sports, but also need to pay attention to their own safety, reasonable choice of professional sports glasses to wear, it is better to exercise in a safe state.
