Six questions and answers about myopia
If you insist on not wearing glasses, will myopia improve?
Many parents believe that if they do not wear glasses all the time, their prescription will not develop and their vision will improve. This idea is incorrect. In principle, if the child is nearsighted and has poor naked eye vision, he should wear glasses; If the naked eye vision is relatively good, and the myopia below 100 degrees is less than 100 degrees, you can temporarily not wear glasses and observe regularly; For children with more than 100 degrees of myopia, glasses should be worn.
If myopia insists on not wearing glasses, it will accelerate the progression of myopia. The child's eye adjustment ability is very strong, myopic children do not wear glasses, when the vision is blurred, they will use their ability to adjust to see distant objects clearly, if this is done for a long time, it will lead to visual fatigue, dry eye, and will accelerate the progression of myopia.
Is it true that the more you wear glasses, the more you wear them?
Many parents have a misconception that the more myopia glasses are worn, the greater the degree. In fact, the increase in myopia is not caused by wearing glasses, but by the growth of the eye axis caused by eye fatigue due to long-term close eye use. Myopia glasses can provide myopic children with clear vision, reduce eye fatigue, and slow down the progression of myopia to a certain extent.
With myopia glasses, should the prescription be smaller?
Some parents are worried that their children's myopia is too large, and they prefer low-correction glasses when they are fitted with glasses. This is wrong. The principle of spectacle fitting is to choose the lowest prescription when you can see clearly. And the premise of this vision is that the visual acuity reaches 10, at this time, the adjustment of the eyes is the most relaxed, and the vision is also the most comfortable. If the vision does not meet this standard, fatigue will be increased, which will lead to the further development of myopia.
What are the correct ways to alleviate myopia?
For children without myopia, the internationally recognized method is to increase the time spent outdoors, more than 2 hours a day, or at least 40 minutes of outdoor exercise can effectively prevent the occurrence of myopia. For children who are already nearsighted, outdoor exercise is also important. At the same time, scientific methods can be adopted for prevention and control, such as the use of orthokeratology lenses or low-concentration atropine eye drops, but each method also has its limitations, and you should also listen to the advice of professional doctors according to your own situation.
Is laser surgery for myopia OK?
For adolescent myopia, the most important thing is to control its development and avoid the occurrence of high myopia or pathological myopia. High myopia can cause serious eye diseases such as glaucoma, fundus hemorrhage, and retinal detachment, and has become the primary cause of blindness. Therefore, the prevention and control of myopia in adolescents is very necessary. The method of laser surgery** myopia is very mature and safe, but it is only equivalent to making a pair of glasses on the surface of the eye, but cannot improve the condition of the fundus, so it can be understood that the surgery only helps us to remove the glasses, but not cures myopia.
Is it okay to be nearsighted**?
At present, myopia is not allowed, once it is determined that it is true myopia, what we can do is to try to control its development and avoid further increasing the depth and causing fundus lesions. Neither laser surgery nor lens surgery can change the condition of the fundus, so that it cannot be fundamentally myopia.
