Many parents lack understanding of their children's visual development
.
Ophthalmologists pointed out that, in fact, children's vision cannot be 1.
Is there a problem with a 4-year-old baby whose farsightedness is 200 degrees?
Not long ago, a mother anxiously brought her baby to the ophthalmology clinic of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine and asked Huang Zhongwei, a professor of the department, for help
.
According to her, although her baby is only 4 years old, his vision in both eyes is only 0.
Huang Zhongwei carefully checked the child and found that her eye position, refractive interstitium, and fundus were all normal, and he made an appointment for her pupil dilation medical optometry
.
Three days later, the results of the examination showed that the child's eye axis, corneal curvature, etc.
"At this age, her vision is normal.
What's more gratifying is that her eyes have a certain refractive reserve
.
" Huang Zhongwei let the parents relax
Use up your refractive reserve ahead of time
Myopia in children will be inevitable
What exactly is refractive reserve? Huang Zhongwei explained that refractive reserve mainly refers to the presbyopic refractive power of children about ten years old, and the power varies according to different ages
.
The degree of ametropia is closely related to the axis of the eye, short for hyperopia, and long for myopia
"Actually, keeping the right amount of hyperopia diopter for children before 10 years old is very beneficial to prevent myopia
.
" Huang Zhongwei reminded that if the eye axis develops ahead and the refractive reserve is consumed in advance, myopia will be inevitable
"Remedy"
It's better to take precautions before they happen
Huang Zhongwei introduced that most parents wait until their children can't see the blackboard clearly before taking them to the ophthalmology department for examination
.
"Although this can be'remedy', it is not as good as preventing
problems before they happen .
" He pointed out that many parents lack understanding of their children's visual development
"If a child has bad eyesight, parents are worried, but if the eyesight is good, it does not mean that myopia will not develop in the future
.
" Huang Zhongwei explained, for example: the same 6-year-old child has the same vision as 0.
Protect eyesight and prevent myopia
"Keep an eye on" the child's diopter
How to prevent and control myopia and protect children's eyesight? Huang Zhongwei's Weapon: "Keep a close eye on" the diopter
.
The change of refractive power is not only related to the length of the eyeball, but also related to the curvature of the cornea and the thickness of the cornea.
These questions can be answered by medical optometry
.
Through medical optometry, a comprehensive understanding of children’s corneal curvature, corneal thickness, axial length of the eyeball (A-scan), diopter, intraocular pressure and refractive interstitium, etc.
, can be combined to analyze children’s refractive reserves.
and so on
.
In addition, children’s eyes are very accommodative, so whether to wear glasses should be analyzed in detail
.
He pointed out that all hyperopia below +1.
50 degrees can be adjusted to focus on the fundus of the distant object.
The ophthalmologist judges that the child’s vision is in line with the age group and the eye position is normal, and it can be observed regularly.
Be sure to wear glasses
.
"Medical optometry is not only for glasses
.
" He reminded that medical optometry can help children who do not need to wear glasses to detect myopia in advance
.
And if the examination results reveal that the child has no refractive reserves, is already myopia or even hereditary high myopia, he can intervene as soon as possible, which is also beneficial to protect the eyes and prevent further deepening of myopia
