Abstract: the myopia rate of children and adolescents in China shows an upward trend, which has aroused the concern and concern of the majority of parents. However, we find that many parents do not know how to use scientific methods to guide their children to prevent myopia, resulting in more and more children’s myopia., Myopia glasses are essential daily necessities for patients with ametropia, so how long does myopia glasses need to be replaced?

Myopia is a problem for many people, especially for middle school students and college students. Heavy studies are easy to lead to eyestrain, so many people have myopia. The myopia rate of children and adolescents in China is on the rise, which has aroused the concern and concern of the majority of parents. However, we find that many parents do not know how to use scientific methods to guide their children to prevent myopia, resulting in more and more children’s myopia., Ordinary myopia patients should generally change their glasses once every two years. One is to adjust the degree, and the other is to “update”. Once there are scratches on the glasses mirror, it will obviously affect its optical correction performance. Therefore, the glasses should be maintained and inspected regularly and updated in time to keep them in good working condition. Teenagers whose degree changes very fast should change their glasses every six months to once a year., The correct way to wear myopia glasses is to have appropriate glasses. In order to see more clearly, some students will choose glasses that slightly exceed their own degrees; Some people think that glasses can correct their eyesight, and specially choose glasses with small degree. These actions are wrong. Wearing appropriate glasses can help us see more clearly. If the degree is too small, you will try to use your eyes because you can’t see clearly, so as to make your eyes tired. If the degree of wearing eyes is too high, it may aggravate eye fatigue and aggravate myopia. Therefore, it is very important to wear appropriate glasses.

myopia glasses should be replaced once every two years.
myopia is a problem for many people, especially for middle school students and college students. Heavy studies are easy to lead to eyesight fatigue, so many people have myopia. The myopia rate of children and adolescents in China shows an upward trend, which has aroused the concern and concern of the majority of parents. However, we find that many parents do not know how to use scientific methods to guide their children to prevent myopia, resulting in more and more children’s myopia.
ordinary myopia patients should generally change their glasses once every two years, one is to adjust the degree, the other is to “update”. Once there are scratches on the glasses mirror, it will obviously affect its optical correction performance. Therefore, the glasses should be maintained and inspected regularly and updated in time to keep them in good working condition. Teenagers whose degrees change very fast had better change their glasses half a year to once a year.
the correct way to wear myopia glasses
the degree of glasses should be appropriate
some students will choose glasses that slightly exceed their own degree in order to see more clearly; Some people think that glasses can correct their eyesight, and specially choose glasses with small degree. These actions are wrong. Wearing appropriate glasses can help us see more clearly. If the degree is too small, you will try to use your eyes because you can’t see clearly, so as to make your eyes tired. If the degree of wearing eyes is too high, it may aggravate eye fatigue and aggravate myopia. Therefore, it is very important to wear appropriate glasses. Wearing appropriate glasses, although not essentially treat myopia, will not damage the eyes.
glasses must be worn as long as myopia
because myopia can be divided into true and false, the principle of wearing glasses is: false myopia does not match, true myopia should match, and the degree of mixed glasses should not exceed that of true myopia. If the degree of mixed myopia is below 100, you can not wear glasses temporarily. If it is above 100, you should wear glasses on a long base, which can effectively avoid deepening myopia. You can use nearsighted glasses when looking far, and do not wear glasses when looking near, which is mainly to reduce the load of ciliary muscle when looking near.
glasses need to be worn all the time
many friends think that if they wear glasses all the time, their eyesight will worsen and they can’t take them off. In fact, this statement is not correct. People with shallow degrees below 300 degrees don’t have to wear glasses all the time. They can do it according to their own preferences. For moderate myopia above 300 degrees, it is recommended to wear glasses all the time, which is more convenient for life, will not cause some problems caused by unclear sight, and can also avoid the deepening of myopia. Generally speaking, it is normal for adults to deepen myopia by 50-100 degrees within a year. In fact, if you still don’t take care of your eyes or know how to use your eyes scientifically after wearing appropriate glasses, myopia may still deepen, but it’s not the reason for wearing glasses.
