In the new semester, how can teenagers protect their eyesight?

The epidemic has changed people\’s lifestyles and also changed the way young people learn. Outdoor activities have decreased, watching TV and computers have increased, and online classes have become the norm. Using your eyes at close range for a long time will undoubtedly increase the burden on your eyes and increase the risk of myopia occurrence and progression. So, how can teenagers better prevent myopia and protect their eyesight? 1. Correct reading and writing 1. The posture for reading and writing should be correct and ensure that the distance between the eyes and the book is more than 30 cm. 2. After reading and writing continuously for 30-40 minutes, take at least 10 minutes of rest. Tips for children to love and protect their eyes: how to cultivate a healthy lifestyle and how to prevent myopia 3. Do not read, write, or use electronic products while walking, eating, in a shaking car, in dim light or under direct sunlight. 4. Maintain the \”Three Ones\” reading and writing posture: the body is one punch away from the desk, the eyes are one foot away from the desk, and the index finger is one inch away from the pen tip. 2. Reasonable screen time Screen viewing behaviors include watching TV, using mobile phones, computers and tablets, etc. Watching screens for long periods of time can cause a series of health hazards, such as eye discomfort (symptoms include eye pain, watery eyes, dry or gritty eyes, blurred vision, etc.), deepening myopia, affecting sleep, and damaging the cervical spine, etc. After using electronic products to study for 30-40 minutes, you should take a break and relax for 10 minutes. Use of electronic products for non-study purposes should not exceed 15 minutes at a time. Therefore, teenagers need to use electronic products correctly and reasonably and strictly limit daily screen time. 3. After scientific intermittent reading or watching a screen for 20 minutes, look up and look 20 feet (6 meters) into the distance for at least 20 seconds, which is the 20-20-20 mantra. Except for online education time arranged by the school, screen time for other purposes shall not exceed 1 hour per day. Develop the habit of consciously closing and opening your eyes with a little force, moving your eyes up and down, left and right, and relaxing your eyes. At the same time, choose indoor sports and artistic activities that suit your physical characteristics and interests to enhance your physical fitness and ensure your physical and mental health. 4. Adequate scientific sleep and reasonable nutrition Adequate sleep and reasonable nutrition are the basis for ensuring healthy vision. Elementary school students should sleep 10 hours a day, junior high school students 9 hours, and high school students 8 hours. They should have a regular schedule to ensure adequate sleep. At the same time, nutrition should be balanced, not picky eaters, not picky eaters, not overeating, eat less sugar, and eat more fresh vegetables and fruits. 5. Once myopia is diagnosed, seek medical treatment as soon as possible and receive scientific correction. If abnormal vision is found, go to a regular ophthalmology medical institution for examination in a timely manner. Myopia refraction is the gold standard for diagnosis. At present, the methods that can be used to prevent and control myopia include wearing frame glasses, orthokeratology lenses (commonly known as OK lenses), etc., which need to be selected and used under the guidance of a doctor, and reviewed regularly at the hospital. At the same time, we must be wary of false propaganda that myopia can be cured. As of now, there is no medical cure for myopia. The only way to avoid worsening of myopia is through scientific correction and improved eye habits. Unscientific treatment may lead to further vision loss and even serious consequences such as eye infection or trauma.
