In the early morning of a digital age, when the sun shines faintly through the curtains into the bedroom, our children don't run out to welcome the day as usual. Instead, their little hands are already gripping their phones and tablets, their eyes glued to the screen. This scene has undoubtedly become a major feature of modern society. But the hidden problem behind this is thought-provoking - according to the latest statistics, more than 5 million primary and secondary school students in China suffer from myopia, and this number is still rising. This is not only a staggering number, but also a shocking wake-up call that we must act now. 
Myopia, an increasingly common problem, is due to more than just genetics. In recent years, with the development of technology and changes in lifestyle, the myopia rate of primary and secondary school students has increased dramatically. There are multiple factors behind this phenomenon. Constant close-up work load: Prolonged hours of reading, writing, and using electronic devices such as tablets and mobile phones keep children's eyes in a constant state of strain. The overuse of the ocular accommodative mechanism gradually leads to the formation of focal points in front of the retina, which in turn develops into myopia. Lack of outdoor activities: Scientific studies have shown that outdoor activities can be effective in preventing the development of myopia. Exposure to natural light helps the eyes focus on distant objects correctly and promotes eye health. However, the current way of life and learning means that children spend a lot of time indoors and lack enough outdoor activities. Bad reading habits: Bad habits such as insufficient lighting, reading too close, and reading while lying down will increase the burden on the eyes and increase the risk of myopia. Unbalanced nutrition: Eating habits also have an important impact on vision. Deficiencies in essential vitamins and minerals, such as vitamins A, D, E, and omega-3 fatty acids, may affect eye health and accelerate vision loss. Extended Dry Goods: Prevention of myopia is not just about avoiding its causes. In fact, by increasing outdoor activity time, improving reading and eye habits, and ensuring a balanced diet, we can effectively reduce the risk of myopia development in children. In addition, regular eye examinations are also a key step in preventing the deepening of myopia, as early detection and intervention can greatly slow down its progression. In China, more than 5 million primary and secondary school students are facing the challenge of myopia, which is not only related to children's vision health, but also affects their learning efficiency and future quality of life. In the face of this situation, daily prevention has become an urgent task. Here are a few effective daily prevention strategies designed to protect children's eyesight from the onset and progression of myopia. 1.Light and Vision: Research on the miracle of tanning has shown that 2 hours of outdoor activity per day can significantly reduce the risk of myopia. The role of natural light is not only to provide vitamin D, but more importantly, it can effectively control the growth of the eyeball and prevent abnormal lengthening of the eye axis. Parents are advised to encourage their children to participate in outdoor activities such as walking, cycling or any outdoor sports to reduce the amount of time spent on electronic screens indoors. 2.Use your eyes wisely: Follow the 20-20-20 ruleTo alleviate eye fatigue caused by prolonged eye use, it's important to practice the 20-20-20 rule: For every 20 minutes of eye use, look at an object 20 feet (about 6 meters) away for 20 seconds. This helps the eye muscles to relax, reducing eye strain and stress, thus preventing myopia. 3.Vision monitoring: Timely detection and interventionParents should take their children for regular eye examinations and take immediate action if signs of vision loss are found. Early detection of myopia can be done by wearing appropriate glasses, conducting vision training, etc., to slow down the progression of myopia. 
Parents and schools are the guardians of their children's vision health, and their roles and actions are crucial to the prevention of myopia. 1.Adjustment of the home environment: To create a good eye environmentParents should provide their children with sufficient light, adjust their reading and writing postures, and ensure that their children's back is straight when reading or writing, and books are kept at arm's length from their eyes. At the same time, limit the amount of time you spend on electronic devices and encourage your child to participate in more outdoor activities. 2.Innovation in school education: To cultivate good eye habits, schools should strengthen the education of students' vision protection, conduct regular vision screenings, and provide corresponding health guidance to students and parents. In addition, schools can create a vision-friendly learning environment for students by increasing the amount of time spent outdoors, adjusting classroom lighting, and seating arrangements. 
3.Popularization of scientific eye education: Enhance the awareness of self-protectionParents and schools should work together to popularize the knowledge of scientific eye use through various channels and methods, so that children can understand the dangers of myopia, realize the importance of myopia prevention, and encourage them to actively practice the habit of scientific eye use in daily life.
