Abstract: myopia can cause blurred vision, and high myopia may affect fundus function. This group is as high as 10% ~ 20% in myopia, and even cause retinal detachment in severe cases.
trick 1: control the damage of electronic products to the eyes: mobile phone > Computer > TV
the deepening of myopia is closely related to the distance between eyes
“Children’s arms are relatively short and they are focused on electronic products. The deepening of myopia is closely related to the distance between their eyes. The closer they are, the damage to their eyes is doubled. Therefore, I usually let children use computers to learn instead of mobile phones.”
the relationship between the adjustment force (i.e. diopter) used by children’s eyes and distance is:
1 / distance (unit / meter) = D (diopter)
. For example, children’s distance from mobile phones is about 20cm, the adjustment force used is 5.00d (500 degrees), the distance from computers 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.
Myopia can cause blurred vision, and high myopia may affect fundus function. This group is as high as 10% ~ 20% in 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?
in fact, children do homework for a long time, 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.” “Don’t think that children sit there for four or five hours to concentrate on their study. In fact, children’s concentration time is very short. Parents should use some skills to let children complete their learning tasks in a short time and give their eyes enough rest time.” The
tactics are checked regularly, and the myopia rate of children in the first tier cities of
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.
in the first tier cities, parents pay more attention to their children’s vision, while in the second and third tier cities, especially some small cities, the attention is low. In fact, it is not just the problem of myopia. Enough attention should be paid to the amblyopia caused by congenital high myopia, high hyperopia and astigmatism. 3% ~ 5% of the children have amblyopia, And some of them are monocular amblyopia, which is difficult for ordinary parents to detect. 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.
