How common is "myopia"?
Look at yourself, look around you, look around, the crowd of people with glasses is on par with the crowd without glasses. Data released by the Health Commission last year showed that the number of myopia in the mainland has exceeded 450 million.
Among them, the incidence of myopia in primary school students is about 30%, and in college students is about 90%. Moreover, the onset of myopia shows a trend of early age, rapid progression and deep degree.
As we all know, myopia, in order to see clearly, you have to wear glasses, but there are always some folk sayings about glasses, and some people are confused about it.
First, "children are short-sighted, afraid that they will never be able to take off their glasses again, and the more they wear them, the more myopia they are"
This statement is first of all wrong, because the increase in the degree after wearing glasses is not the fault of glasses, but is related to the child's eye habits, growth and development, genetics and other factors.
In addition, the child's myopia may still be in progress, wearing glasses can only correct the myopia situation at that time, after wearing glasses, pay more attention to develop good eye habits. Children with a degree of myopia above 100 degrees after pupil expansion and refraction can be worn when they need to use their eyes, such as looking at the blackboard and writing homework, and once the degree exceeds 200 degrees, they must insist on wearing glasses.
Second, "Wear glasses as long as you can see clearly?" ”
This concept is also wrong, the standard of "seeing clearly" is too simple, just ordinary conventional refraction, the purpose of which is to make the refractive error person see the object clearly.
The doctor recommends a more formal medical optometry, to be carried out in a regular hospital, to have a high-precision comprehensive refractometer, there are also strict requirements for optometrists, must be familiar with clinical ophthalmology and optometry knowledge of the optometry doctor, the refraction content includes refractive index, astigmatism axis, adjustment force, binocular monosopic function, spoke collection function, binocular adjustment balance, main eye discrimination, etc.
"Is it normal for children to have astigmatism and farsightedness?" ”
not necessarily. For children, moderate hyperopia and moderate astigmatism are indeed a normal physiological phenomenon during their development, but this farsightedness and astigmatism have different ranges at different ages, and once they are out of range, they should also be given timely treatment.
When parents find that their children have astigmatism and farsightedness, do not worry and worry, go to a regular hospital for medical optometry, and listen to the advice of professional doctors.
4. "Wearing glasses will cause the eyes to protrude?" ”
Wearing glasses does have a certain impact on the appearance, some people are worried that wearing glasses will protrude the eyeballs, even if the myopia does not wear glasses, in fact, the protrusion of the eyeball is often a situation that will occur in highly myopic people, because the axis length of their eyeballs is longer.
From the beginning of myopia, attention is paid to protecting the eyes from evolving into high myopia, which can avoid protruding eyeballs.

The content of this book is worth every defender of visual health to understand and learn, and the road to visual training still has a long way to go, on the basis of mastering the existing principles and methods, we should look at more scientific and advanced technology, multidisciplinary communication, multidisciplinary integration for visual training to open up more possibilities, for more people to light up a bright.
Starting from the initial development of visual training, this book elaborates on the physiological and neurological basis of visual training, as well as the various categories and rehabilitation categories that have gradually been enriched in the development of the discipline. The chapters are detailed according to the classification of visual training, and the overall organization is clear, thus trying to make it easy for beginners to learn and master. Visual training related points are clearly defined and not repeated, helping readers to answer questions and remember to apply. Guided by the principle of visual training, the book elaborates various targeted methods of visual rehabilitation, which has a certain degree of scientificity and rigor, laying a solid knowledge foundation for the clinical practice of optometry and visual rehabilitation workers.
