Now parents let their children receive exercise since childhood, not only for the children's body and brain exercise, but also for their will and character. But outside of sports, parents' main concern is safety. Studies show that eye injuries caused by sports, especially football, basketball, rugby and so on, account for about 10% of the total number of injuries. For children who wear glasses, especially when they are engaged in strenuous sports activities, they are often worried about injuries caused by the breakage of glasses and frames, and are forced to remove the glasses, which will not only affect their sports performance, but also increase the non-safety factors caused by vision problems. How to choose glasses for children who often exercise? Frame glasses or contact lenses?

   At present, the only suitable lens material for sports protection is Polycarbonate (PC tablet, also known as space tablet). PC chips were first discovered in 1898 and are mainly used in aerospace and space products. In the 1930s, PC materials were modified and used in the field of lenses. The impact of high speed and high energy produced in sports is far beyond the limit that other lens materials can bear, and only PC can provide enough protection. The choice of frames is as important as the lenses. Not all frames are sporty. The American Society for Testing and Materials (ASTM) and the Canadian Standards Association (CSA) have detailed regulations. The rimless, perforated glasses that today's students wear to look good are not as safe for students who play a lot of sports. Especially the boys who like playing football and basketball. The screws of rimless glasses are easy to loosen, and in case of collision or various accidents, they can not protect the eyes at all, but also make the eyes prone to injury. Such as corneal abrasion, eye abrasion, retinal detachment and internal bleeding. Frames with anklets on the legs are prone to breakage because of the hinges, which can cause injuries when the frames or hinges come into contact with the eyes. People had better wear professional sports glasses when they exercise. But experts believe that the general demand as long as wearing a pair of more firm glasses can be, also do not have to special. Frame recommended formability good titanium alloy, plate, frosted material can be, frame a little wider is more firm. In addition, for people who exercise a lot, the frame must be the right size, even if it is a little tight. For both beautiful, and love sports people, might as well be paired with two pairs of glasses, usually can wear rimless, sports and then change firm.

Contact lenses have unique advantages over rimmed glasses. When the physical activity is more intense, the human body is in a larger physical dynamic, when the collision occurs, the contact lens wearers have more stable dynamic vision and better depth vision; With contact lenses, you can see things more naturally, with a larger field of vision, a non-distorted peripheral field of vision, and a more realistic object size. And unlike rimmed glasses, which slide down the nose and are not fogged, they are not affected by sweat, rain and dust; Moreover, when wearing contact lenses, you can wear windproof goggles, sunglasses and diving goggles at the same time to meet more needs during sports.

  But in water sports, such as swimming, water polo, generally do not recommend wearing contact lenses, in order to avoid lens loss, or microbial infection. It is recommended to remove contact lenses to avoid increasing the chance of infection because the lenses themselves can attract pathogenic microorganisms, which can put people at risk of infection even after swimming. If you must wear contact lenses, it is recommended to choose large-diameter soft contact lenses to ensure the stability of the lens; Choose thicker lenses that are less prone to wrinkling and creasing. After water exercise, it is best to wait 20 to 30 minutes for the lens to resume activity before taking it out. Rinse your eyes with eye drops, clean your lenses with a strong surface activator, and disinfect them with a strong disinfectant after cleaning. The use of sunbeam lenses is encouraged. Once the eyes are red after swimming, and the point of eye drops is still not alleviated, but also accompanied by photophobia tears, blurred vision symptoms, to go to the hospital as soon as possible. When participating in outdoor activities, if the environment is dry, dusty, cold, it is recommended to wear glasses or discard contact lenses.
