Abstract: for children in growth and development stage, we can not only measure whether the eyes are normal by naked eye vision, but also monitor at least three indicators: naked eye vision, diopter and eye axis length., For most parents of children with myopia, when they go to the hospital for an optometry, they hear that it is pseudomyopia, and then they breathe a sigh of relief. Thank God it is not true myopia. Unexpectedly, within six months, these pseudomyopia has become true myopia, and the child’s eyesight has begun to deteriorate rapidly. What’s the matter?, First of all, let’s look at what is pseudomyopia. In short, when the hospital does mydriatic optometry, the difference between the diopter before and after mydriasis is called pseudomyopia. Generally, there are three situations, such as: 1 Before mydriasis -2.0 (myopia 200 degrees), after mydriasis -1.5 (myopia 150 degrees), 2. Before mydriasis -0.75 (myopia 75 degrees), after mydriasis is 0, there is no myopia, 3. Before mydriasis -0.50 (myopia 50 degrees), after mydriasis + 0.50, (50 degrees of hyperopia). In the first case, parents will immediately pay attention to it, while in the second and third cases, parents feel light, which makes it easy for children to become true myopia soon. Why? In fact, most children today are true myopia at the age of three or four. True myopia mainly refers to myopia caused by the lengthening of the eye axis. Under normal circumstances, children are hyperopia reserve For example, a 6-year-old child should normally have 200 degrees of hyperopia, We also call it physiological hyperopia reserve (you can search Baidu), but most children now have no reserve of hyperopia. That is to say, compared with the normal situation, these children have been myopia for more than 200 degrees, the eye axis has become longer, and true myopia has occurred. Yesterday, I received a consultation that the child is 5 years old, the right eye is 750 degrees, the eye axis is 24.5mm, the left eye is 1250 degrees, and the eye axis is close to 27mm. It’s terrible. The adult eye axis is only 24mm , I’m older than an adult at the age of 5. Why does the eye axis grow longer?,
for most parents of children with myopia, go to the hospital for an optometry and hear that it is pseudomyopia, and then take a long sigh of relief. Thank God it is not true myopia. Unexpectedly, within six months, these pseudomyopia has become true myopia, and the child’s vision has begun to deteriorate rapidly. What’s the matter?
first let’s look at what is pseudomyopia. In short, the difference between the diopter before and after mydriasis is called pseudomyopia when the hospital does mydriatic optometry. There are generally three situations, such as:
1 Before mydriasis -2.0 (myopia 200 degrees), after mydriasis -1.5 (myopia 150 degrees)
2, before mydriasis -0.75 (myopia 75 degrees), after mydriasis is 0, without myopia
3, before mydriasis -0.50 (myopia 50 degrees), after mydriasis + 0.50, (hyperopia 50 degrees)
In the first case, parents will pay attention immediately, while in the second and third cases, parents feel light. This relaxed child will soon become true myopia. Why?
in fact, most of today’s children have true myopia at the age of three or four. True myopia mainly refers to myopia caused by the lengthening of the eye axis. Under normal circumstances, children have hyperopia reserves. For example, a 6-year-old child should have 200 degrees of hyperopia under normal circumstances, We also call it physiological hyperopia reserve (you can search Baidu), but most children now have no hyperopia reserve, that is to say, compared with the normal situation, these children have more than 200 degrees of myopia, the eye axis has become longer, and true myopia has occurred.
Yesterday, I received a consultation that the child is 5 years old, the right eye is 750 degrees, the eye axis is 24.5mm, the left eye is 1250 degrees, and the eye axis is close to 27mm. It’s really terrible. The adult eye axis is only 24mm, and it exceeds the adult at the age of 5. Why does the eye axis grow longer?
let’s take a look at this interesting picture. When our eyes are looking close, the ciliary muscle inside the eyeball will contract and compress the lens to become thicker before we can see clearly. When the ciliary muscle contracts, it will pull inside the eyeball and pull the eyeball into an oval shape. Now children aged one or two have fallen in love with TV and mobile phones in recent months, The eyes are under high load regulation for a lot of time, that is, there is a tension inside the eyeball for a lot of time, and the ciliary muscle is under high load contraction for a long time, the ciliary muscle will strain, congest and spasm and lose its growth ability. The child’s body will grow tall, the face and eyeball will grow up, and the eyeball will be bound by the ciliary muscle with long-term spasm during the growth process, Forced to grow into an oval, the front and rear axes are getting longer and longer, forming high myopia.
and
after understanding this principle, parents must not relax their vigilance because of a doctor’s pseudomyopia. For children in growth and development, they should not only measure whether their eyes develop normally by naked eye vision, but also monitor at least three indicators: naked eye vision, diopter and eye axis length. Now, children around the age of 5 generally have no hyperopia reserve, and the ocular axis is significantly higher than the normal value, that is to say, they are true myopia. Unfortunately, many parents feel good when they see their children’s vision of 0.8 and 1.0, but in fact it has been very serious. 99% of parents have missed the best expectation of their children’s vision.
and
to protect children’s eyesight, we must start with infants and young children. Don’t wait for myopia to worry, which requires the attention of every parent; At present, children around the age of 10 generally have myopia of about 200 degrees. If their eye use methods and habits are not changed, most of them will develop into ultra-high myopia of more than 800 degrees in adults. In fact, myopia prevention and control is not difficult. Control children’s reading and writing posture and distance, and the speed of myopia will be reduced by at least half.
finally, briefly talk about the value and significance of children’s vision health care and myopia prevention and control.
first, find problems in time and nip myopia in the bud;
2. Quickly improve eyesight and avoid myopia when wearing glasses;
3. Restore normal growth and development ability in the eyes and avoid entering high myopia (the most important);
4. Changing behavior habits is not only conducive to vision, but also conducive to physical health and performance improvement. A child who is away from mobile phone TV can calm down and study well.
