The summer vacation is coming to an end, and the countdown to the new academic year is about to begin. Is the child's vision "defense war" at the moment of sounding the trumpet of victory, or is it the situation where they have to request medical aid all the way back? Regardless of the situation, maintaining eye health should be a long-term behavior that runs through a person's entire life. Scientifically and reasonably protecting the eyes should start from now on, starting with every daily detail. During the summer vacation, some parents arrange for their children to "fly before the birds" to preview the new school year's curriculum. Some parents cultivate their children's artistic hobbies, such as playing piano, chess, calligraphy, and painting, and encourage them to participate in sports, play ball games, and swim to enhance their physical fitness. Different choices may lead children's vision to develop in different directions. If you use your eyes closely for a long time, it is easy to develop myopia, such as studying at desk, learning musical instruments, playing with mobile phones or tablets, etc. If you frequently use your eyes from a long distance and look into the distance, it can effectively alleviate the development of myopia and help prevent myopia. For example, regularly participating in outdoor activities, playing basketball, football, volleyball, table tennis, etc. Therefore, parents should guide their children to read and exercise simultaneously every day, without neglecting them. Take a break every half hour to do anything and have a tolerance. For example, watching TV or playing games every day usually requires no more than half an hour of rest, sightseeing or outdoor activities, and relaxing the eyes. If this degree is not properly controlled, prolonged close eye contact can easily lead to myopia. Similarly, if the time spent studying and doing homework exceeds half an hour, it is also necessary to look far to relieve eye fatigue. This is often overlooked by parents and children, so it is not only important to focus on controlling the use of electronic products, but also to have a "break" during homework. Adhering to good eye habits not only helps us maintain a good mental outlook, but also helps us protect our vision. When doing homework, keep your eyes at arm's length from the book and not write on your stomach; The posture of holding the pen is also very important. You should not wrap the pen with your thumb, but rather expose the tip of the pen, otherwise it is easy to tilt your head when writing, causing the distance between your eyes and the book to be asymmetrical, which affects your vision; After the start of school, one should not look sideways at the blackboard with one's head tilted, as this can also cause uneven visual development. If you have perseverance and persist for 21 days, it is possible to develop a good habit. High hyperopia requires strengthening close range eye use. A group of children are not restricted by the above regulations and need to use their eyes more closely. They can look at electronic products - seeing this, parents who are always worried about their children's myopia express disbelief. Actually, this is a group of highly farsighted children. Hyperopia refers to the focus of light passing through the refractive stroma of the eye, which is located behind the retina. It is the opposite of myopia, but the manifestation is a decrease in vision, which can only be distinguished by optometry. For children with high hyperopia, it is necessary to engage in close range fine visual activities, such as reading and writing, playing piano, chess, calligraphy and painting, and also reading electronic products. This is actually beneficial for them. If the method of preventing myopia is followed to protect the eyes, it will cause the degree of farsightedness to slow down and prevent the removal of farsightedness glasses.
