After the child’s myopia, most parents have made such a mistake?

Abstract: the above is the genetic probability. In the clinic, about 10% of children with myopia aged 3-6 are due to genetic myopia. Some doctors have observed from thousands of medical records that if children have myopia and astigmatism at the age of 5-10, one or both of their parents have eye diseases such as myopia, amblyopia and astigmatism.

now many kindergartens often do routine vision screening for children. It is generally believed that the normal visual acuity of children in small class is 0.6, 0.8 in middle class and 1.0 in large class. If it is lower than this value, it may be considered that their visual acuity is low. At the two sessions held a while ago, some members pointed out that many children wear glasses before they go to primary school. Then, what causes children’s myopia? Is myopia related to heredity? What should parents do scientifically after children’s myopia?

when will children develop normal vision?

when a child is born, the structure of his eyes seems to be the same as that of an adult, but his eyesight is very poor. He can’t even recognize the first line of his eyesight chart. After birth, vision can develop only when it is stimulated by the surrounding environment. At the age of three, the average visual acuity developed to 0.6. When entering primary school at the age of six, it had developed to 1.0 as adults. If this development process is hindered and the child’s vision does not reach the due level of that age, it is amblyopia.

do parents have myopia and will it be passed on to their children?

survey shows that, Both parents are highly myopic (generally more than 600 degrees), and the probability of myopia inherited from the baby is about 40%; if one of them is highly myopic, the probability of inheritance can be reduced to 20%; however, if both parents are low myopia, the probability of inheritance is much smaller.

The above is the genetic probability. In the clinic, about 10% of children with myopia aged 3-6 are due to genetic myopia. Some doctors have observed from thousands of medical records that if children have myopia and astigmatism at the age of 5-10, one or both of their parents have eye diseases such as myopia, amblyopia and astigmatism.

therefore, excluding the causes of the acquired environment, children aged 3-6 years old have high myopia, which is closely related to heredity.

what are the wrong practices of parents for children with myopia?

after confirming that the child has myopia, what should parents do? Due to the lack of correct eye care knowledge, many parents have some misconceptions and prejudices about myopia, and intervene in the correction of children’s myopia accordingly. Here are some misconceptions and prejudices that parents often have.

misunderstanding 1: children are still young and do not need glasses.

some parents worry that children wear glasses at a young age and will be ridiculed by their peers. They also think that if children wear glasses for a long time, their myopia will deepen and they will never take off their glasses. The truth of

and

: whether the degree of myopia is deepened has little to do with glasses, but is caused by the change of refractive state of the eye itself. Wearing glasses is to correct myopia, and wearing correct glasses itself will not lead to myopia. Glasses of appropriate degree can also effectively prevent the deepening of myopia. Parents and children should face wearing glasses with a good attitude. Misunderstanding 2 of

and

: glasses do not need to be worn all the time. Some parents feel that children only need to wear glasses when listening to classes, looking at blackboard, writing and reading. They can not wear glasses in ordinary life. Truth of

and

: at present, the mainstream view is that glasses need to be worn all the time, so as to obtain better visual quality. Only when the degree of myopia is very small (less than 200 degrees) and the clarity of looking near is not affected, you can consider wearing glasses when looking far away and not when looking near. If the degree of myopia is deep, you need to wear glasses all the time.

misunderstanding 3: eye protection lamp and eye protector can alleviate myopia

Now, many businesses in the market sell eye protection lamps and eye protection instruments to parents under the banner that products can effectively alleviate or treat children’s myopia. Parents believe them and buy them for children at a high price. Truth of

and

: in fact, this kind of eye protection equipment has a certain effect on eliminating eye fatigue, but it has no fundamental improvement effect on delaying myopia.

misunderstanding 4: refuse to dilate the children’s pupils, which will hurt the eyes.

some parents take their children to the hospital to check their eyesight. When they hear the doctor say they want to dilate their pupils, they waver. Some parents believe that children are too young and mydriasis will hurt their eyes. Truth of

and

: mydriatic drugs themselves do not play the so-called role of “mydriasis”, but play another role – Paralyzing ciliary muscles. If you want to measure the true refractive state of the eye, you should relax the ciliary muscle. Children’s eye adjustment ability is very high. If they do not have mydriasis, they may detect too high myopia, Or they have no myopia and the examination results show myopia (pseudomyopia).

dilation of pupils after mydriasis, which will produce photophobia, etc. These are normal phenomena. Parents don’t need to worry. They just need to avoid strong light irradiation after mydriasis and don’t use their eyes at close range.

eye protection starts from small:

  1. Don’t let children read or watch TV for a long time too early, and don’t let children use mobile phones to play games for a long time.

  2. Don’t read or watch TV in a dark place or in a shaking car.

  3. Eat a balanced diet and eat more foods containing vitamin A or carotene.

  4. When the sun is strong, properly help the child wear a sun hat or sunglasses to avoid direct eyes.

  5. Receive a visual examination regularly for about half a year.
