"Children in the fourth grade of primary school will begin to prepare for the beginning of the small rise, many parents in the class will take their children directly to the training institutions after school every day, until seven or eight o 'clock." I have to finish my school work at home, and I can't go to bed until 10 o 'clock. Tired is tired, but in order to go to a good junior high school, do not spell it." Looking at his son who has deepened his best place to buy eyeglasses in the new semester, Mr. Li of Shijiazhuang is most worried about the pressure of studying.

"The school encourages children to exercise for an hour after school every day, but children often finish their homework at 9 p.m., so they can't spare the time to exercise." Zhang Qiuling is a parent of a third-grade primary school student, she introduced that the time for children to exercise is given to homework.

"In the past, when it comes to college entrance examination, the pressure is only high school and college entrance examination, but in recent years, 'junior high school' has also joined, in order to meet various examinations, primary and middle school students can only spend the main time on academic study." Zhang Qiuling said that in the face of the pressure to study, schools and parents are prepared.

The reporter's investigation found that at present, when some schools implement the national "sunshine sports" requirements, there is still a gap in intensity and time, and even cultural classes occupy sports activities.

In the way of learning, the popularization of electronic products has become another incentive for the young age of myopia. "In the homework assigned by the school, there is often one or two electronic homework, such as reading English picture books in the mobile APP. Every time the child finishes reading, he will play a small game for at least 20 minutes." Zhang Qiuling introduced that in the school where the child is located, there is a special "Pad class", which uses electronic products for a longer time every day, and the impact on vision cannot be underestimated.

In addition, more and more after-school tutoring classes have adopted online education models, and many institutions have developed online courses and electronic homework, electronic testing platforms, "classes, homework, tests, all completed on mobile phones or computers, not only increased the burden of children's schoolwork, but also contact with electronic products for longer time, causing adverse effects on eyesight." Cui Zengmin believes that these are worse for teenagers' precarious eyesight.

However, children are used to wearing glasses. Outside a training institution in Shijiazhuang, a reporter asked a second-grade pupil wearing glasses: "How can you wear glasses at such a young age?" The child pushed his glasses and said, "Several students in the class are wearing them, and they will wear them sooner or later."
