Abstract: the reason why the myopia rate of children in first tier cities is very high is that compared with children living in rural areas, the time of outdoor activities is much shorter. Experiments have proved that outdoor exercise time of no less than 20 hours a week is helpful to prevent and control myopia., Children in cities have a high rate of myopia, and parents may be to blame. One of the most common scenes is: when adults go out to dinner and children are noisy, parents often give him a mobile phone or iPad immediately and let him play by himself. In fact, this practice is the culprit of hurting their children’s eyes., Parents should not be the ones who hurt their children’s eyesight., As a parent, director Liu Wenyan has his own set of vision management for his children. How can children’s eyes escape the “magic claw” of myopia? Let’s listen to his three tricks ~, one of which is to control the damage of electronic products to the eyes: mobile phone > Computer > TV. At home, director Liu Wenyan has strict control over the use of electronic products by children, so that children have “sequelae” – retreat from their parents’ mobile phones. When the child entered the fourth and fifth grade, director Liu Wenyan began to let him search for some information on the Internet and use electronic products to assist learning, but the use method is also exquisite., The degree of myopia deepening is closely related to the distance between eyes. “Children’s arms are relatively short and they stare at electronic products attentively, while the degree of myopia deepening is closely related to the distance between eyes. The closer they are, the more damage they do to their eyes. Therefore, I generally let children use computers instead of mobile phones.”, Director Liu Wenyan explained, The relationship between the adjustment force (i.e. diopter) used by children’s eyes and distance is:

as a parent, director Liu Wenyan has his own way of managing his children’s eyesight. How can children’s eyes escape the “claw” of myopia? Let’s listen to his three tricks ~

to control the damage of electronic products to the eyes: mobile phone > Computer > TV
and
at home, director Liu Wenyan has strict control over the use of electronic products by children, so that children have “sequelae” – retreat from their parents’ mobile phones. When the child entered the fourth and fifth grade, director Liu Wenyan began to let him search for some information on the Internet and use electronic products to assist learning, but the use method is also exquisite.
“the degree of myopia deepening is closely related to the distance between eyes.
” children’s arms are relatively short and they stare at electronic products attentively. However, the degree of myopia deepening is closely related to the distance between eyes. The closer they are, the more damage to their eyes will be doubled. Therefore, I generally let children use computers instead of mobile phones. ”
director Liu Wenyan explained, The relationship between the adjustment force (i.e. diopter) used by the child’s eyes and distance is:
1 / distance (unit / meter) = D (diopter)
. For example, the child’s distance from the mobile phone is about 20cm, the adjustment force used is 5.00d (500 degrees), the distance from the computer is about 50cm, and the adjustment force used is 2.00d (200 degrees), the distance to watch TV is generally more than 3 meters, and only 0.33d adjustment force is used at most, i.e. 33 degrees. Therefore, parents should pay special attention to the damage of electronic products to eyes. Mobile phones > computers > TV.
As an ophthalmologist, the reason why director Liu Wenyan attaches so much importance to myopia is not only that myopia will cause blurred vision, but also that high myopia may affect fundus function. This part of the population is as high as 10% ~ 20% in the population of myopia, and even cause retinal detachment in severe cases.
tips two help children overcome procrastination
some parents may say that children have heavy schoolwork. Even if they don’t play mobile computers, do they always have to do homework? My children do 11 o’clock every night. Can they not be short-sighted?
and
in fact, children spend a long time doing homework, not necessarily more homework. It may be that the child’s “procrastination” has been committed!
children should also learn time management when they study.
“my children used to do the same. Their homework can be done late at night from 8:00 p.m. later, I asked him to finish it before 9:30 p.m. and put it away if he couldn’t finish it.” Director Liu Wenyan did this because he knew the child’s psychology well. “Don’t think that the child is sitting there for four or five hours to concentrate on learning. In fact, the child’s concentration time is very short. Parents should use some skills to let the child complete the learning task in a short time and give his eyes enough rest time.”
and
sure enough, director Liu’s children were worried about going back to school and being criticized by their teachers. They obediently completed their homework as soon as possible and no longer had to “fight” until midnight. The
and
tactics are checked regularly, and the myopia rate of children in the first tier cities of
and
is very high because the time of outdoor activities is much shorter than that of children living in rural areas. Experiments have confirmed that outdoor exercise time of no less than 20 hours a week is helpful to the prevention and control of myopia: under dynamic sunlight, the body secretes dopamine, which may slow down the growth of ocular axis, and within the intensity that the eyes can bear, dynamic sunlight can delay the progress of myopia more than indoor light source. So parents might as well encourage their children to get close to nature and be wild outdoors, which is also good for the prevention of myopia. At the same time, director Liu Wenyan suggested that in the first tier cities, parents pay more attention to children’s vision, while in the second and third tier cities, especially some small cities, the degree of heavy vision is low. In fact, it is not only a problem of myopia, but also a problem of congenital high myopia, high hyperopia Amblyopia caused by astigmatism should be sufficientAttention: 3% ~ 5% of the children in the crowd have amblyopia, and some are monocular amblyopia. It is difficult for ordinary parents to detect it. If they are not well intervened and treated as children, it may affect the children’s life.
therefore, regular eye examination and establishment of refractive files are very important. Refractive files can closely track the changes of children’s diopter. The corresponding visual examination can also evaluate the health status and visual function of the whole eye, such as whether there is visual fatigue and dyslexia, how the coordination function of hands and eyes, and whether the color vision function is abnormal, so as to find the potential problems of the eye as soon as possible.
