People with shallow myopia can recover slowly without glasses?

Abstract: the eye development of teenagers is not stable. For myopia under the age of 18, the annual increase of glasses is generally no more than 100 degrees. In contrast, people who wear glasses occasionally or never wear glasses, The long-term defocus (hazy) and fatigue of the eyes will lead to poor visual acuity, decreased eye convergence ability and easier increase of myopia.

In life, we often meet some people with low myopia. They often wear glasses sometimes and sometimes don’t. According to the Internet, people with shallow myopia don’t often wear glasses, and they can gradually get rid of myopia. Is this true? Can people with low degree of

and

not often wear glasses?

the correct answer is: if you are short-sighted, wearing glasses is good for your eyes, It has nothing to do with the degree.

“once myopia is diagnosed, the doctor will recommend wearing glasses often, which has nothing to do with the degree of myopia. Patients with high myopia must wear glasses for a long time, and patients with low degree are no exception. If they don’t wear glasses often or the degree is not suitable, it will only increase eye fatigue and deepen the degree of myopia.

Because if the eyes can not get clear visual signal stimulation, the ciliary muscle responsible for regulating the function in the eyes may overwork, which can easily lead to visual fatigue, even strabismus, amblyopia and other problems. Therefore, even if the degree of myopia is not high, you should wear glasses for a long time to prevent excessive strain of ciliary muscles.

in addition, some people believe that whether it is necessary to wear glasses for a long time is related to age, and teenagers and adults should not be generalized. However, teenagers and adults can really generalize about this. They’d better wear it for a long time rather than occasionally. The eye development of

and

teenagers is not stable. For myopia under the age of 18, the annual increase of glasses is generally no more than 100 degrees. In contrast, people who wear glasses occasionally or never wear glasses, Long term defocusing (hazy) and fatigue of eyes will lead to poor visual acuity, decreased eye convergence ability and easier increase of myopia.

Adults often wear myopia glasses, which is conducive to alleviate eye fatigue, protect eyes, and delay the occurrence of presbyopia. Only those adult myopia patients with low eye requirements do not have visual fatigue symptoms at ordinary times, and exclude eye diseases such as strabismus. They can wear glasses only when they need to obtain clear images.

therefore, once myopia is found, it is best to go to a regular hospital for optometry in time to remove pseudomyopia and obtain accurate and appropriate diopter. It is better to wear glasses for a long time after glasses matching, rather than only when it is strongly needed. At ordinary times, you should also pay attention to eye hygiene. Every 40 ~ 50 minutes of eye use, rest for 5 ~ 10 minutes. You can look at the distance or green scenery to relax the ciliary muscles. This can avoid visual fatigue and reduce the risk of deepening myopia.

why does the degree of myopia continue to deepen?

myopia is a very common phenomenon. Mild myopia will continue to develop into moderate myopia, and moderate myopia will continue to develop into high myopia. Why? Why does myopia continue to deepen?

first of all, myopia is generally limited by 300 degrees. When you are outdoors below 300 degrees, you will not squint. At this time, you can see clearly and will not be blurred, so you are not recommended to wear glasses. It is only recommended to wear it in class, watching TV and watching computer.

and

are followed by more than 300 degrees. I feel that I won’t squint at things, but in fact, seeing things is fuzzy, so I will use greater adjustment to see things in the distance. In this way, according to the fuzzy theory of Ophthalmology, your myopia will speed up and it is easy to form astigmatism. The principle of myopia deepening is that when you see things blurred, the ciliary muscle of the eye needs to use greater adjustment force. Over time, the ciliary muscle will be tired and lose elasticity, forming false myopia. Over time, the eye axis will lengthen, forming true myopia. Low degree true myopia is transformed into moderate myopia below 600 degrees because of new fatigue and new pseudomyopia. And then develop into high myopia. Therefore, we recommend wearing glasses all day above 300 degrees.

the third myopia does not wear glasses and looks at things in a fuzzy state, which will only accelerate the development of myopia and form astigmatism faster. Astigmatism degree is large, easy to headache, more difficult to correct than simple myopia

and

. What factors are easy to cause myopia? According to the research of the

and

genetic factors

and

, the incidence rate of myopia in the next generation is high in the families with high myopia. The high myopia has a certain genetic tendency. It is generally recognized that the genetic tendency of the general myopia is not very obvious.

eyes are too close.

teenagers have strong eye adjustment. They can still see objects when the distance between books and eyes is 7 ~ 10cm. However, if they often read and write at this distance, the adjustment of eyes will be extremely tense, which can form pseudomyopia. If the long-term adjustment is excessive, the ciliary muscle cannot flex flexibly, the eyeball wall is compressed and gradually extends, and the anterior and posterior axis of the eyeball becomes longer. If it exceeds the normal value, axial myopia is formed, which is called true myopia. The normal reading distance shall be 30 ~ 35cm.

and

use their eyes too long

and

some teenagers and children don’t rest for 3-4 hours in a row, such as reading, writing, doing homework and watching TV, or even go to bed late at night, which not only affects their health, but also makes their eyes overburdened. It is generally advocated that you should take a break or look into the distance for a while after reading, writing or watching TV for 30 ~ 40 minutes.

the lighting light is too strong or too weak

if the light is too strong, such as sunlight, it will cause strong reflection, stimulate the eyes, make the eyes uncomfortable, and it is difficult to see the font. On the contrary, the light is too weak, the written lighting is insufficient, the eyes can’t see the font clearly, and the head will move forward and close to the book, The above two conditions can make the eyes easy to fatigue, excessive eye adjustment or spasm and form myopia.

“read books while driving or walking”

“some teenagers make full use of their time, reading or reading while walkingReading in a walking carriage is bad for your eyes. Because the carriage is shaking, the body is shaking, the distance between eyes and books cannot be fixed, and the poor lighting conditions aggravate the burden of eye adjustment. Often this may cause myopia. Many teenagers like to read in bed, which is a bad habit. Because people’s eyes should be kept horizontal to read, Make the adjustment consistent with the collection (radiation) to reduce eye fatigue. If you lie down to read, your eyes are not in the horizontal state, the distance between your eyes and the book is inconsistent, the line of sight of your eyes is inconsistent up, down, left and right, and the illumination on the book is uneven, which will make eye adjustment nervous, and it is easy to move the book closer to your eyes, which can increase the burden on your eyes and form myopia over time.

malnutrition

and

lack of calcium, zinc and other vitamins will increase the probability of myopia in adolescents during development. In terms of diet, first of all, don’t give teenagers too many sweets. It is recommended that children eat more hard food and eat enough protein, especially animal protein. Foods containing vitamin A are also good for the eyes. Eating more fresh vegetables and fruits is also good for your eyes.

[listen to what experts say] the highest incidence of juvenile myopia is at the age of 7 ~ 15, of which 10 ~ 15 is the most critical stage of juvenile eye development and the most prone to problems. Visual acuity re examination can be conducted once before and after school, so as to know the child’s visual acuity and facilitate the change of children’s visual acuity after adjusting the holiday.
