Many parents have turned! Do this to keep children away from myopia!

Abstract: there are two kinds of low vision, one is physiological low vision, the other is pathological low vision. The so-called low physiological vision is that the child’s eyes are relatively slow, but not very serious. Pathological low vision is that the eyes may have organic lesions.

children suffer from myopia, and the most anxious is their parents. However, in the process of treatment, parents have many misunderstandings in the diagnosis and treatment of children’s myopia. Misunderstanding 1 of

and

: is a child’s poor eyesight myopia?

now kindergartens in Guangzhou are doing routine vision screening, usually twice a year, but only for vision. 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 is considered that their visual acuity is low.

and

can also be divided into two types: physiological vision and pathological vision. The so-called low physiological vision is that the child’s eyes are relatively slow, but not very serious. Pathological low vision is that the eyes may have organic lesions.

and

misunderstandings, but most of the health teachers in the school are not professional ophthalmologists. Once they find out which child has poor eyesight, they will tell their parents that “your child has myopia”. In fact, this statement is wrong.

and

have many reasons for poor vision, not just myopia. On the contrary, 95% of the poor vision of preschool children is not myopia, but caused by hyperopia and astigmatism. Misunderstanding 2 of

and

: if you have good eye habits, you won’t be short-sighted?

and

parents often ask why some children watch TV, play mobile phones and read books on their stomach all day, and they won’t be myopic. Our children pay great attention to eye hygiene, but they are still myopic early.

and

suggest that most children can go to the hospital for two examinations when they enter the park, that is, about 3 years old: one is mydriatic optometry, and the other is to measure the eye axis through instruments. Predict the development trend of children’s refractive state in the future through the results of the two examinations.

for example, for a 3-year-old child, the refractive state measured after mydriatic optometry is 300 degrees hyperopia, while under normal circumstances, a 3-year-old child should have 200 degrees hyperopia, so from the development trend, the child will not be easy to get myopia in the future.

and then measure the ocular axis, because the length of the ocular axis is also closely related to age. For a normal 3-year-old child, the length of his eye axis is about 21.5mm. If the child’s measured eye axis length is 21 ~ 21.5mm, it also shows that it is very good, because the longer the eye axis is, the easier it is to get myopia, and the shorter the eye axis is, the more remote the visual state is.

and

through the measurement of these two indicators, we can roughly understand the refractive state of the child’s eyes and infer whether the child is prone to myopia in the future. In this way, parents can be targeted. For example, for children who are not prone to myopia, parents can let them learn piano and painting. If the measurement is bad and children are more likely to suffer from myopia in the future, I usually ask parents to consider whether it is important to pursue their children’s achievements or whether they are more concerned about their children’s vision and their health.

: myopia, don’t wear glasses too early?

some school-age children are short-sighted in grade one and two. Many parents insist on not giving their children glasses, “Once you put on your myopia glasses, you can’t take them off, and your myopia will get deeper and deeper. In fact, it’s not the case at all.

① myopia will develop. With the increase of age, the length of the eye, that is, the axis of the eye, will increase, and the degree of myopia will increase.

② at the stage of eye development, children use their eyes too much, and myopia develops faster.

③ children with myopia will squint at distant objects. In the long run, myopia will develop faster. Misunderstanding 4 of

and

: may children be “pseudomyopia”? The misunderstanding of

and

now the medical community is playing down the view of “false myopia” more and more, because the essence of “false myopia” is not “myopia”. The so-called “pseudomyopia” in

and

refers to the fatigue visual acuity decline due to excessive eye fatigue. It may be a transient visual acuity decline due to too much homework and too much eye use recently. After mydriatic optometry, the refractive state is mild hyperopia or no myopia, which is a completely normal refractive state, So it is called “pseudomyopia”.

in fact, the proportion of such children is very small, less than 5% of children with myopia, but parents always feel that “their children must suffer from pseudomyopia, and pseudomyopia will get better.” This is also a big misunderstanding.
