How to make their children not myopia?

Abstract: Children’s arms are relatively short and focus on electronic products. The deepening of myopia is closely related to the distance between eyes. The closer they are, the damage to eyes will be doubled. Therefore, it is suggested that parents let their children use computers instead of mobile phones.

how to make their children not myopia?

1. Control the damage of electronic products to eyes: mobile phone > Computer > TV

in modern life, one of the most common scenes is that adults go out to dinner and children are noisy nearby. 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.

and

the degree of myopia deepening is closely related to the distance between eyes.

and

children have short arms and concentrate on staring at electronic products. However, the degree of myopia deepening is closely related to the distance between eyes. The closer they are, the more damage to eyes will be doubled. Therefore, it is suggested that parents let their children use computers 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.

Parents must pay attention to the problem of myopia. This is not only because myopia will cause blurred vision, but also because high myopia may affect fundus function. These groups are as high as 10% ~ 20% in the population of myopia, and even cause retinal detachment in severe cases.

2. 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 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.

many children can do their homework from 8 p.m. to late at night. Parents can give their children time control and require their children to finish it before 9:30. If they can’t finish it, they should put it away. The reason for this is that 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. ” With

and

, children will worry about being criticized by their teachers when they go back to school. They will finish their homework as soon as possible and will no longer have to “fight” until midnight.

III. pay attention to the cultivation of eye use and reasonable diet

we must cultivate correct eye use habits and cultivate children to develop good eye use habits. Read in a place with sufficient light. Turn on the lamp and put the desk lamp in the front left when reading at night, which is conducive to protecting your eyes. To maintain a correct reading posture, sit upright, the book should be more than one foot from the eyes, the pen tip should be one inch from the fingers, and the chest should be one punch from the table. The reading time should not be too long. At the same time, we should combine work and rest in order to better prevent myopia.

and

often eat cereals. The trace element chromium contained in cereals is beneficial to eyes; Also eat more calcium food; Usually eat some nuts, which can exercise facial muscles, drive eye exercises, or insist on doing eye exercises.

and

IV. regular inspection and more wild

and

the reason why the myopia rate of children in the 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 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.
