In recent years, the onset age of myopia in patients has significantly advanced. Current research shows that there are two peak periods of myopia development, one is 7-8 years old and the other is 13-14 years old. "Li Li, director of ophthalmology at the National Children's Medical Center and Beijing Children's Hospital, told reporters. Generally speaking, genetic factors, poor eye habits, and basic eye diseases can all affect the vision of children and adolescents. The development of myopia is closely related to long periods of close eye use and limited outdoor exercise. Scientific prevention of myopia should focus on good eye habits, balanced diet, and sufficient sleep. Ensure outdoor activities. Li Li said that research has shown that increasing daily outdoor activities can slow down eye axis growth and delay the onset of myopia. Outdoor activities under sunlight can effectively increase dopamine levels in the eyes, increase choroidal thickness, inhibit axial growth, and control the development of myopia. Therefore, it is best to engage in outdoor activities when there is ample sunlight. It is recommended that teenagers adhere to outdoor activities for at least two hours every day. Preschool children can increase their outdoor activities to three or four hours. Reduce close eye contact and electronic product usage. Children under 3 years old are advised to avoid using electronic products as much as possible. If children aged 3-6 need to use electronic products, they should reduce their close eye contact time, not exceeding 15 minutes each time, and limit it to less than 1 hour per day. Overlooking is a common way to relieve eye fatigue, where both eyes can look out at the green plants outside the window and as far away as possible. Each time you use your eyes at close range for 20 minutes, keep your eyes at a distance of 6 meters for no less than 20 seconds. In addition, eye care exercises, clean towels, and hot compresses can also help alleviate symptoms of dry and tired eyes. For children and adolescents, it is also important to cultivate personal hygiene awareness and habits, wash hands frequently at school and home, and avoid contact with infections. Ensure sufficient sleep and a balanced diet, sleep no less than 10 hours a day, and consume more vegetables and fruits such as carrots and blueberries that are beneficial for eye health. Li Li suggests that children and adolescents undergo a visual examination every 6 months or so. At different stages, the focus of eye health screening for children varies. 0-6 years old is a very important stage for myopia prevention and control. When conducting eye health screening, it is important to understand whether a child has a reserve for farsightedness and whether the reserve is sufficient. At the age of 3, it is normal to have a hyperopia reserve of 175 to 200 degrees. If there is a hyperopia reserve of 125 to 150 degrees at the age of 6, and a hyperopia reserve of 75 to 100 degrees at the age of 8, it can delay or even prevent myopia in children, and reduce the incidence of myopia. Eye health checks are very important for children and adolescents, "Li Li said. Abnormal manifestations such as head tilt, squinting, and squinting may be accompanied by visual problems such as amblyopia and strabismus, as well as other potential fundus lesions. These all need to be detected through eye screening as soon as possible to reduce the occurrence of high myopia and pathological myopia. Experts point out that once a child is nearsighted, on the one hand, it is necessary to wear glasses promptly according to the advice of doctors and optometrists, and on the other hand, pay attention to daily eye use to delay the development of myopia. Review visual acuity, eye axis, and refractive status every 3-6 months to dynamically understand the progression of myopia in the child
