In recent years, the myopia rate of children has been increasing year by year, and there are more and more children wearing glasses in kindergartens and schools. However, many parents worry that after their children wear glasses, will their myopia get deeper and deeper? There is no scientific basis for this belief. In fact, the deepening of myopia after wearing glasses is mainly related to two factors. One is acquired factors, that is, do not pay attention to eye hygiene, looking too close (such as watching TV, computer games, reading books, etc.) for too long, reading and writing do not pay attention to the sitting posture, etc., resulting in excessive spasm of intraocular regulation muscles, myopia gradually deepen. The second is congenital factors, such as abnormal development of the eye itself, long anterior and posterior diameters, or conical cornea, lens abnormalities and other lesions. Some parents think that their children may have pseudomyopia, so they don’t need to worry about it and it will get better with time. This view is also incorrect. Children with vision loss should go to the hospital as soon as possible, the doctor will be based on the situation of dilated pupil optometry, fundus examination and other professional examination, if there is myopia after dilated pupil optometry that is the real myopia, not the so-called pseudomyopia. Some children may even be diagnosed with other eye diseases so that they can be treated in a timely manner without delaying their condition and regretting it for the rest of their lives. Some children and their parents take wearing glasses as a kind of burden, and sometimes wear them, sometimes not, thinking that “if you wear glasses often, you will never be able to take them off again, and your myopia will get deeper and deeper.” In fact, in general, more than two or three hundred degrees of myopia glasses, if a moment to wear a moment to take off, will make the eyes are often in a state of unstable regulation of fatigue, but will make myopia deepen. Only less than two or three hundred myopia children, you can choose to see far to see the blackboard when wearing glasses, see close to write when removing glasses. In addition, some parents think that every time the optometry point dilated eye medicine is harmful to the child’s eyes, which is also a misunderstanding. Young people’s eyes ciliary muscle regulation is very strong, if the pupil is not dilated, ciliary muscle regulation can not be relaxed, optometry is not accurate, and easy to adjust the spasm due to the pseudomyopia as true myopia to prescription, but instead of glasses should not have been wearing glasses on the wrong child, the child harm. Therefore, parents and friends, let’s get out of the eyeglasses misunderstanding, and really play a positive role in protecting children’s eyesight.
