Parents see that children’s poor eyesight does not mean myopia

Abstract: the main causes of abnormal vision in children are amblyopia, abnormal refraction (pathological hyperopia and astigmatism) and other eye diseases such as eye trauma. Therefore, the primary task of eye health care is to early find and effectively treat amblyopia, and actively prevent eye trauma and other common eye diseases.

survey shows that 30% of children aged 3 ~ 7 have low vision. Many parents and teachers often think that children’s poor vision is myopia. So, how to scientifically understand and implement effective intervention for this specific group?

first of all, we should understand some characteristics of children’s vision. Children’s eyes have a development process from low to normal. Although 3-year-old children can measure their eyesight, it can be lower than the normal standard. Low vision is often only a superficial phenomenon, which can be caused by a variety of reasons, physiological or pathological, normal vision or abnormal vision, which can be determined by relevant examination.

the visual acuity measured by the current visual acuity chart is the main sensory function, especially in children. There are many influencing factors, so we should not draw a conclusion easily. Normal far vision is not equal to normal refraction (such as hyperopia), which can be determined by mydriatic optometry. Children’s visual function has a variety of performance, vision is only one of them, and vision can be divided into far vision and near vision. Generally speaking, vision refers to far vision, and near vision is often ignored. In fact, near vision can also reflect the quality of visual function. According to the characteristics of children’s eye development, 3 ~ 6 years old is the key period in order to promote visual development and effectively cure eye diseases. If you miss this period, your visual function will be difficult to recover.

in order to strengthen cultural education, some kindergartens and schools increase the visual burden, which makes children’s eye adjustment nervous and easy to show low far vision (i.e. myopia), but some of these are temporary phenomena, not necessarily myopia. “Myopia” and “myopia” are two different concepts. “Myopia” refers to a phenomenon of low far vision and normal near vision (vision concept), which is very common in children, especially in kindergartens and lower grade pupils. There are many reasons for myopia. Most eyes have corresponding functional or organic changes, but myopia is not necessarily myopia. “Myopia” refers to the refractive state, which can be determined by mydriatic optometry. Therefore, although myopia is very common in young children, it does not mean myopia.

and

are the main causes of visual abnormalities in children, such as amblyopia, refractive abnormalities (pathological hyperopia and astigmatism) and other eye diseases such as eye trauma. Therefore, the primary task of eye health care is to early find and effectively treat amblyopia, and actively prevent eye trauma and other common eye diseases.

parents should be fully concerned about their children’s growth; We should not only pay attention to moral and intellectual education, but also pay attention to physical and mental health. It is very important to ensure or strive for a pair of bright eyes. It is recommended that parents understand some basic knowledge of children’s eye health care, actively prevent eye trauma, pay attention to the changes of children’s vision, regularly check their vision, and pay attention to children’s visual reactions, such as squinting, strabismus, etc. At the same time, regardless of the visual acuity, it is best to accept a mydriatic optometry. Once an eye disease is found, actively cooperate with the diagnosis and treatment. In particular, it is not necessary to use commercial health nutrition and eye medicine.

once parents find that their children’s vision is often low, they don’t have to be too nervous. They can simply judge whether their children’s vision is often physiological or pathological (abnormal vision) according to the following:

▲ age: the older the age, the greater the possibility of abnormal vision.

▲ low normal degree: visual acuity is significantly reduced. If < 0.6, it can be listed as abnormal visual acuity.

▲ whether it can be corrected: if the corrected visual acuity is less than 0.9, it is abnormal visual acuity.

▲ symmetry: the difference of binocular vision is more than 2 rows, and the eyes with poor vision are mostly abnormal vision.

▲ near vision: if near vision < 1.0, it is abnormal vision (normal ≥ 1.0).

▲ static refraction: Atropine mydriatic optometry is a pathological refractive state, which is abnormal vision.

▲ if there are other eye diseases, low vision is often pathological.
