In recent years, the problem of myopia in children has become increasingly serious and has become a global public health problem. According to statistics, the myopia rate of primary school students in China has reached 457% and 74 for junior high school students4%, and 83 for high school students3%。So, what causes the high incidence of myopia in children?And how can we prevent it?
First of all, excessive use of electronic devices is one of the important causes of myopia in children. With the development of science and technology, mobile phones, tablets and other electronic products have become the main tools for children to learn Xi and entertainment. However, staring at a screen for long periods of time can lead to eye strain and increase the risk of myopia.
Secondly, the lack of outdoor activities is also a factor that contributes to myopia. Studies have shown that spending more than 2 hours outdoors a day can effectively reduce the incidence of myopia. This is because outdoor light stimulates the retina to release dopamine, which inhibits the growth of the eyeball axis and prevents myopia.
In addition, poor eye Xi can also affect vision. For example, reading or writing too close to a book, or too much light or too much light can put a strain on the eyes and cause myopia.
So, how to prevent myopia in children?First, parents should limit the amount of time their children spend using electronic devices and encourage them to participate in outdoor activities. Second, develop good eye Xi, such as maintaining a correct sitting posture and taking breaks every 40 minutes. Finally, it is also important to have regular eye exams so that vision problems can be detected and treated in a timely manner.
In general, the problem of myopia in children cannot be ignored. Through scientific methods, it is entirely possible to reduce the incidence of myopia and protect children's eye health. Let's work together to create a brighter world for the next generation.
