Myopia usually starts in children and teenagers, and parents are the ones who suffer the most from the embarrassing situation of wearing glasses at a young age. The reality is that there is no better way to treat myopia than to wear glasses to correct it, so prevention is important. Children are ignorant, later myopia or not, largely determined by their parents, so the role of parents can not be ignored, then, as parents, parents how to play a role, the relationship can not be said not much. Since there is no cure, prevention should of course be in the first place. The prevention of any malady follows the same logic, first of all, we should understand the cause of the malady, and only from the cause can we talk about the so-called prevention. So, what are the causes of myopia? One of the questions that parents often wonder and confuse is why there is an unusual increase in myopia now when there used to be less of it. Then, first of all, we should come to see how the living environment we live in now, including clothing, food, housing and transportation, is different from the past, and how the behavior of parents and students now is different from the past. Overdrawn eyesight: Nowadays, in cities and even towns, you can often see many parents leading their children to various extracurricular classes during holidays, and at a young age, they should be mainly playing, but they are tied up in a classroom with little space, staring at the books close at hand or watching the animations played on the projector uninterruptedly or whatever. The impact of electronic products: In this day and age, a variety of electronic products are ubiquitous, almost all require the use of vision, children in addition to the classroom often have to look at the display, back home or in class, inevitably will come into contact with the cell phone, more sadly, now the cell phone is also intelligent, and the network is inseparable, the main function of the cell phone seems to be no longer limited to calls, but more used to The answer is yes. If parents fail to do this, children are less likely to do so. Domestic and foreign differences: In terms of various remedial training, the degree of development in China is much higher than abroad, and the difference between developed and underdeveloped areas is also obvious, corresponding to the difference in the incidence of myopia is also obvious. Influence of parental behavior: Many children’s “good learning” behaviors are passive and forced by parents who want their children to become children, obviously, all kinds of tutorial classes are not children’s own initiative to go, therefore, the parents’ decision and guidance is crucial, parents who put tutorials and fight the so-called “starting line If parents regard tuition and the so-called “starting line” as important, children will only be forced to obey, so the root of the problem is the parents.
