Nowadays, parents let their children receive exercise from an early age, not only for the exercise of the child’s body and brain, but also for the sharpening of their will and character. But the most important concern of parents after sports is the safety issue. Studies have shown that eye trauma from sports accounts for about 10% of all traumatic injuries, especially soccer, basketball, rugby, etc. For children who wear glasses, especially during strenuous sports activities, there is often a fear of injury from broken lenses and frames of frames, forcing them to remove their glasses, which not only affects their sports performance, but also increases the non-safety factor caused by vision problems. How do you choose glasses for children who play sports a lot? Should they choose frames or contact lenses? Currently, the only suitable lens material for sports protection is Polycarbonate (PC sheet, also known as cosmic sheet or space sheet), which was discovered in 1898 and is mainly used in astronautics, space products and other areas of life. In the 1930s, PC material was improved and used in the field of lenses. The high speed and high energy impacts generated in sports are far beyond the limits of what other lens materials can withstand, and only PC can still provide sufficient protection. The choice of frame is as important as the lenses. Not all frames are suitable for sports. The American Society for Testing and Materials (ASTM) and the Canadian Standards Association (CSA) have detailed regulations. The current student population likes to wear those rimless, perforated glasses to look good, but these glasses are not as safe for students who play sports regularly. Especially boys who like to play soccer and basketball. The screws of the rimless glasses are easy to loosen, and in case of a collision or various accidents, they do not protect the eyes at all, and also make them prone to injury. Such as corneal abrasion, eyelid abrasion, retinal detachment and internal bleeding. Frames with ankle chains on the temples are prone to breakage because of the hinges, which can make the frame or hinge contact with the eyes and cause injury. People are better off wearing professional sports glasses when playing sports. However, experts believe that it is enough to wear a more solid pair of glasses for general needs, and there is no need to make special ones. The frame is recommended to form a good titanium alloy, plate, frosted material can be, frame a little wider on the more solid some. In addition, people who often exercise with the frame must be the right size, even if a little tighter does not hurt. For people who want to look good and love sports, you may want to have two pairs of glasses, you can wear frameless ones, and then change to firm ones when you play sports. Compared to frame glasses, contact lenses have their own unique advantages. When sports activities are more strenuous, the body is in greater physical dynamics, collisions occur when contact lens wearers have more stable dynamic vision and better depth vision; wear contact lenses to see things more natural, a larger field of vision, the peripheral vision is not distorted, the size of objects more real; and unlike frame glasses, will slide down the nose, and will not fog up, not affected by sweat, rain and dust; and When wearing contact lenses, you can wear windproof glasses, sunglasses and diving goggles at the same time to meet more needs when playing sports. However, contact lenses are generally not recommended for water sports, such as swimming and water polo, in order to avoid loss of lenses or microbial infections. Because the lenses themselves can absorb pathogenic microorganisms, making a person still under the threat of infection after swimming, it is recommended that contact lenses be removed to prevent increased chances of infection. If you must wear contact lenses, it is recommended that you choose soft contact lenses with a large diameter to ensure lens stability; choose thicker lenses that are less prone to lens wrinkling and folding. It is best to wait 20 to 30 minutes after water sports and wait for the lenses to resume activity before removing them. Rinse the eyes with eye drops, clean the lenses with a stronger surface activator, and disinfect the lenses with a stronger disinfectant after cleaning. Encourage the use of daily disposable lenses. Once your eyes become red after swimming and are not relieved even after ordering eye drops, and are accompanied by photophobia and tearing and blurred vision, go to the hospital early. When participating in outdoor activities, it is recommended to wear frames or disposable contact lenses if the environment is dry, dusty and cold.
