Abstract: for parents whose children are nearsighted, they often think that they are nearsighted anyway, and the whole class of children are nearsighted, so they can only let it go. It is this idea that makes parents neglect prevention and control, and finally makes children become high myopia and cause a series of high myopia complications., Today, I’d like to share with parents three fatal mistakes that children are most likely to make in myopia prevention and control., The first fatal mistake is that 1.0 is good eyesight. I often listen to my parents. My doll can see 1.0, and the eyesight is good. Is 1.0 good eyesight? Our normal vision can develop to 2.0, (very few people can reach 4.0). 1.0 is only half of 2.0. In other words, I have 2.0 vision, which is the goal I can see at a distance of two meters. Children with 1.0 vision need to see at a distance of one meter. 1.0 vision is only the minimum vision requirement for some jobs and industries with high eye requirements in the country. It is not the standard of good vision. It is the normal vision of children aged 8-10 The strength should reach 2.0, lower than 1.5, indicating that the eyesight has begun to decline, which should be paid great attention., When parents think that 1.0 is good vision, they often miss the best time for vision improvement and intervention. From the perspective of myopia prevention and control, when vision begins to decline, vision can be easily recovered through appropriate rest and changing eye use methods. Once vision falls below 0.3, the situation will become very bad., The second fatal mistake, 2 ignoring children’s physiological hyperopia reserve,
today shared with parents three fatal mistakes that are most likely to be made in the prevention and control of children’s myopia.
the first fatal error
1 mistakenly believes that 1.0 is good eyesight
I often listen to my parents. My doll can see 1.0, and the eyesight is good. Is 1.0 good eyesight? Our normal vision can develop to 2.0, (very few people can achieve 4.0). 1.0 is only half of 2.0. In other words, I have 2.0 vision. I can see the target at a distance of two meters. Children with 1.0 vision need to see it at a distance of one meter.
The vision of 1.0 is only the minimum vision requirement for some work and industry with high requirements for eye use. It is not the standard of good vision. The normal vision of children aged 8-10 should reach 2.0, which is lower than 1.5, indicating that the vision has begun to decline and should be paid great attention to.
when parents think 1.0 is good vision, they often miss the best time for vision improvement and intervention. From the perspective of myopia prevention and control, when vision begins to decline, vision can be easily recovered through appropriate rest and changing eye use methods. Once vision falls below 0.3, the situation will become very bad.
the second fatal error
2 ignores the child’s physiological hyperopia reserve
our normal visual development will experience the process from hyperopia to emmetropia. When we were young, we were hyperopia because of our small size and small eyeballs. Every child has physiological hyperopia reserve, The following data are the reference values of hyperopia reserve for children aged 4-12:
4-year-old hyperopia 250 degrees
5-year-old hyperopia 225 degrees
6-year-old hyperopia 200 degrees
7-year-old hyperopia 175 degrees
8-year-old hyperopia 150 degrees
9-year-old hyperopia 125 degrees
10-year-old hyperopia 100 degrees
11-year-old hyperopia 75 degrees
12-year-old hyperopia 50 degrees
roughly means that the hyperopia reserve decreases by about 25 degrees with the increase of one year. Under normal circumstances, the child’s vision will gradually enter the face-up with the puberty period, and then be maintained. But the current situation is that many children run out of hyperopia reserves at the age of four or five, and begin myopia at the age of six or seven. As long as they start myopia at the age of six or seven, or children with myopia of more than 300 degrees before the age of 12, if they can’t get effective prevention and control and intervention, 99% will develop into high myopia of more than 600 degrees after three or five years of youth development!
here, parents should first pay attention to that children’s uncontrolled watching TV and playing with mobile phones is the culprit leading to poor vision development and premature and excessive consumption of hyperopia reserves. Premature consumption of hyperopia reserves will inevitably lead to children’s myopia.
the third fatal error
3 let children’s myopia continue to deteriorate
medical big data tell us that most high myopia is in junior high school (puberty) is formed. Why? The increased academic burden and eye load are one reason, but the deeper reason is that myopic children lose their growth ability due to intraocular muscle imbalance, which restricts and imprisons the normal growth of the eyeball. Let’s take a look at the following picture:
We can see from the internal anatomy of the eyeball that a circle of ciliary muscle grows at about one-third of the front end of the eyeball, and a lens is hung in the middle of the ciliary muscle. We all know that myopia begins with the spasm and stalemate of the ciliary muscle. After the spasm of the ciliary muscle, it loses its ability to regulate, the blood circulation is poor, the oxygen supply capacity is insufficient, and the muscle gradually loses its ability to grow, This is equivalent to tying a ring at the front of the eyeball. After the child enters puberty, the body grows taller, the face becomes larger, and the eyeball also becomes larger. At this time, this ring will bind and imprison the eyeball to grow up, down, left and right. It is forced to grow on the front and rear axes, the front and rear axes become longer, and the degree of myopia will become higher and higher, and this myopia is irreversible.
for parents whose children are already short-sighted, they often think that they are short-sighted anyway, and the whole class of children are short-sighted, so they can only let it go. It is this idea that makes parents neglect prevention and control, and finally makes children become highly myopia and cause a series of complications of high myopia.
