Ten misunderstandings about myopia

Abstract: the degree is determined according to the wearer’s eye function, wearing comfort, correction method and other factors. There are corresponding principles for adding and subtracting the degree, and the degree cannot be increased or decreased at will. If the deviation between the glasses children wear and the actual degree of their eyes is too large, they will not only fail to achieve clear vision, but also the degree will increase faster.

■ now is the era of information explosion. A lot of knowledge can be obtained through the network, and medical treatment is no exception. However, in the absence of medical background, it is difficult for us to identify the authenticity of these information, resulting in some wrong perceptions of myopia. Some wrong perceptions not only have no protective effect on our eyes, but will accelerate the growth of myopia. Let’s take a look at you. Did you win?

all “myopia” in the following expressions are true myopia. Everyone’s impression of “false myopia” does not belong to myopia, but the state of eye adjustment tension. When our eyes relax, this “false myopia” will disappear.

wrong view 1:

do not wear glasses when you are nearsighted. You can’t take them off when you wear them, and the degree is rising!

doctor explained:

■ glasses have only one function, that is to make your eyes see clearly. Many people think they can’t live without glasses after wearing glasses. Is this the fault of glasses? In fact, it’s because the outside world is blurred when we take off our glasses, which is very inconvenient for life, study and work, so we can’t live without them. Glasses don’t hurt our eyes. After the occurrence of myopia, especially for children in physical development, the degree of myopia will continue to increase. Scientific research and clinical experience show that the growth rate of myopia without glasses will be faster. You don’t have to carry this black pot glasses.

wrong view 2:

institutions outside use… Methods to treat myopia, children’s myopia is good!

doctor explained:

■ again, myopia is incurable. In order to seek benefits, some institutions take advantage of parents’ love for their children and use various means to convince parents that their methods can completely cure myopia. Parents do not hesitate to pay any price and miss any opportunity for their children’s eyes, but they do not know that they delay their children’s eyes. It’s no accident to see any organization with advertisements such as “myopia is cured, no money if it’s not good”. It must be deceptive.

wrong view 3:

myopia is not high. Now pay attention to the habit of using your eyes and it will get better slowly.

doctor explained:

■ myopia is irreversible. Once a child is still in physical development, myopia will not decrease but will continue to increase without special envoy intervention. Most myopia is caused by overdevelopment. We can’t make the developing eyes grow inversely, just as we can’t make a tall person shorter.

wrong view 4:

resolutely do not wear glasses except when they have to, because the eyes tend to become convex when wearing glasses.

doctor explained:

■ some researchers compared the protrusion of high myopia with that of normal eyes. On average, the former is 0.94mm more prominent than the latter, which is about 1mm more prominent. In fact, the difference is not obvious from the appearance. The reason why people who often wear glasses feel that their eyeballs are very protruding after removing them is that we usually see the eyes of myopia through lenses, and myopia lenses have the visual characteristics of narrowing the eyes. When we remove the lenses, the size of the eyes we see is normal, which is “larger” than the eyes of myopia we often see through lenses before, When the eyes feel “bigger”, we mistakenly think they are convex. It may also be that the skin around the eyes is whiter than other parts of the face, forming a prominent illusion. So glasses don’t really make the eyes convex. ”

wrong view 5:

myopia glasses can be worn all the time as long as they are not broken, and there is no need to recheck again.

doctor explained:

■ with the increase of our use time, the lens surface will produce some small scratches. The more obvious the scratches are, the greater the impact on our vision. Moreover, through the scratched lenses, it is easy to cause fatigue and discomfort to the eyes for a long time. After some lenses are used for a long time, the lenses are yellowing and aging, which affects the transmittance of the lenses and reduces the clarity. The frame is easy to deform after long use, and the change of shape will affect the parameters, especially for patients with high astigmatism. In addition, our degree is not invariable. Myopic people usually have refractive examination together for half a year.

wrong view 6:

is wrong, the child still has astigmatism!!! What can I do—— Worry too much about astigmatism.

doctor explained:

■ most astigmatism depends on the shape of the cornea. For people without astigmatism, the shape of the cornea is equivalent to the shape of a basketball, The cornea of people with astigmatism is equivalent to the shape of football (exaggerated point), which shows that the curvature in two vertical directions is different. Conventional astigmatism has been formed before birth and will not change the day after tomorrow, but it is also different from the eye posture (looking askew, lying down, squinting) there is a certain relationship, but the fluctuation range is small and generally considered unchanged. Astigmatism is different from high myopia, which will not further harm our eyes except affecting the clarity.

wrong view 7:

degrees are tens of millions. Don’t be so sufficient. Just look around and see what you are doing.

doctor explained:

■ the degree is determined according to the wearer’s eye function, wearing comfort, correction method and other factors. There are corresponding principles for adding and subtracting the degree, and the degree cannot be increased or decreased at will. If the deviation between the glasses children wear and the actual degree of their eyes is too large, they will not only fail to achieve clear vision, but also the degree will increase faster.

wrong view 8:

glasses can be worn far away. Look
