I'm Zhao Xiaodao and I'm an ophthalmologist.
Recently, there is a video on Douyin that has become popular. A parent shared his "failed experience of myopia control", saying that in 4 years, he spent 60,000 yuan wearing OK glasses, and each eye still increased by more than 200 degrees. In fact, this kind of prevention and control effect is not a failure, and an annual increase of 50 degrees has played a role in traditional prevention and control technologies, and one of the comments exploded:
Seeing this comment, I couldn't help but be stunned for a moment, ophthalmologists have worked hard to popularize science for so many years, but they still haven't been able to change many people's views on myopia——。
But is that really the case? Let's take a look at the evolution of myopia.
According to the White Paper on Eye Health in China, the myopia rate of 6-year-old children in China is as high as 14.3%, and the myopia rate of primary school students is as high as 35.6%. Assuming that a child starts myopia at the age of 8, if it is not actively prevented and controlled, then the probability will rise at a rate of 75~100 degrees per year, and by the time the child is 18 years old, it may reach 800~1000 degrees of myopia. Even if some measures are taken to control the growth rate of 25%, then it will be around 850 degrees.
If you can control 50% of the myopia at about 600 degrees, if you can control 75%, then the 18-year-old will only have 350 degrees of myopia, and if you can control 100% or even higher, then you can let the child return to the ranks of non-myopia.
At this time, some people may want to say, are low-grade myopia and high-grade myopia both myopia? just a little higher and a little thicker lens.
Wrong! Wrong. Clinically, myopia above 600 degrees is usually defined as high myopia, at this time, the eye axis usually exceeds 26mm, and the eye then enters the risk state of eye disease. Fundus medicine may devote half of its energy to dealing with some fundus diseases associated with high myopia. Because the eyeball is too large, the retina of the fundus will be stretched very thin, like a mosquito net, which may be pulled at any time, and then a lot of fundus problems such as retinal detachment and macular splitting, including glaucoma, cataract, optic nerve atrophy and other diseases may come to the door. In addition, as the eyeball grows larger, the density of the dense cones in the eye will become sparse, so the corrected vision will also decrease, and it is difficult to use glasses.
If you think that myopia prevention and control is overly anxious and don't know what retinal detachment is, you can listen to the sharing of this patient's friend. Let's take a look at our painstaking advice to parents to adopt strong myopia prevention and control measures and hold back the development of myopia, whether they are scaring you or protecting you.
Ophthalmologists often share the case of patients with high myopia, such as the following patient, whose eyes are 1200 degrees, and the fundus is very fragile, and the retina is detached just by rubbing the eyes.
From time to time, there will be several tragic cases of retinal detachment and blindness caused by retinal detachment in young patients with high myopia on the Internet, which is embarrassing, and this is actually a misfortune that fundus doctors have to face every day.

If you go to the postoperative ward of the fundus department of the ophthalmology hospital and look at the highly myopic patients who have to keep their heads down when walking, eating, and sleeping, I believe you will never say such ignorant words as "Isn't it just myopia, just wear glasses".
Preventing high myopia is actually curing the disease. Why do ophthalmologists spend so much energy on preventing and controlling myopia, in fact, they don't want so many children to grow up to become highly myopia.
And now children are getting myopic earlier and earlier, a child is 8 years old 100 degrees, and there is a high probability that it will exceed 600 degrees when he is an adult. We need to take a lot of effective measures to help children stop myopia. Taking strong measures to reduce the growth rate of myopia from 100 degrees/year to 0 degrees or 25 degrees/year is a good treatment, of course, there are still many children who can realize the dream of declining degrees, that is, perfect prevention and control.
Taking effective myopia prevention and control measures for your child as soon as possible can prevent your child from becoming a highly myopic person, so that when your child grows up, even if he has low myopia, he does not have to worry too much. Because the eyes of low myopia are actually relatively healthy, there are very safe myopia removal surgery in adulthood, laser, femtosecond, ICL, etc., which are very reliable, and you can take off the glasses with a minor operation and return to a completely normal life, which is very important to control myopia.
For children who are not myopia, it is necessary to block the arrival of myopia;
For children who already have low myopia, it is necessary to control the growth rate;
For children who are already highly myopic, preventing blindness is our goal.
Take advantage of the period when children's eyeballs are soft and can be shaped, use the most effective means not to waste and live up to the precious golden period of myopia prevention and control, and avoid regrets in the future.
This is the meaning of myopia prevention and control.
Parents' attention and choice determine the degree of myopia and eye health of children. I spend a lot of energy to do science popularization, that is, I hope that the majority of parents will do myopia prevention and control work for their children as soon as possible, and learn more about myopia prevention and control. That's why I wrote the book "Eye Care Policies of Great Powers - A Practical Guide to the Prevention and Control of Myopia in Children and Adolescents". Because in the clinic, I have seen too much chagrin and remorse. Many parents may let their children go when they are still young, or their eyesight is not bad, and wait until they are nearsighted, and the eye axis will rise slowly, and soon grow to 25mm or 26mm eye axis. The child's eye axis begins to become dangerous when it reaches 26mm, and at this time, in order to protect the eyes, all entertainment and learning are begun to be abandoned.
Going back to that comment, "What's the point of anxiety?", is it really excessive anxiety to pay attention to the prevention and control of children's myopia? Of course not, how important it is for children to prevent high myopia and reduce the restraint and worry of wearing glasses! Not to mention the impact on children's future career choices, national defense students, doctors, pilots, and other professions have strict requirements for vision. In recent years, some regions have even included good or bad eyesight in children's high school entrance examination results. Now that the world is changing so fast, we may not know what to learn will be useful for our children's future, but we know very well that the health of the body, especially the health of the eyes, will definitely be useful for the future. If parents do not take precautions and miss the precious golden period of myopia prevention and control for their children, when the children grow up and their eyeballs are fixed, they can't help if they want to.
Again, the more attentive parents are, the more benefits their children will be. In fact, the knowledge of myopia prevention and control is not very complex and profound, and parents can learn by themselves and become experts. There are already many parents who are ahead of some professionals, which is great, and the efforts put in by parents have also paid off in their children.
Preventing myopia and controlling myopia is far more important than we think, and it is by no means as simple as wearing an extra pair of glasses. Of course, it is useless to be anxious in vain, we must turn anxiety into down-to-earth learning and action, master and use truly effective prevention and control methods, and open a protective umbrella for children.
As a professional, we must actively learn, now there is a lot of new knowledge about myopia prevention and control, and the prevention and control efficiency is also very strong, you can't bind yourself to the backward cognitive cocoon and stagnation, you can't just be satisfied with the annual growth of 50 degrees, and then tell parents "You are already very good". At present, there are many new knowledge and methods, such as diffuse diffuse transmission and de-laserized red light, and far-image fogging therapy, which need to be learned, practiced and verified, and learned to systematically, comprehensively and scientifically evaluate the benefits, costs and risks of new methods.
It is the duty and obligation of every professional to effectively help children stop the growth of myopia, and to achieve zero growth of myopia and live up to the expectations of parents is the greatest medical ethics. Before you don't have enough practical experience, at least do the doctor be cautious, don't do reverse science, after a few years parents reacted, found that you said "no" (cell experiments, animal experiments, population experiments, massive practice cases, long-term clinical applications, multi-center randomized controlled studies, JAMA top journal papers, expert consensus, overseas certification, overseas application), in fact, it has long been there, and it will be a pity to find that your children have missed the scientific and technological dividends they should have enjoyed because of your backward cognition, and missed the golden prevention and control period for children.
