Winter vacation + Spring Festival, the highlight moment of "hi turning the sky" at home is coming. However, looking at mobile phones and playing games is cool for a while, and if you keep looking at mobile phones and playing games, your eyes will not be cool. Children, in particular, can become "little glasses" if they are not careful. Dear parents who are broken for their babies, hurry up and raise the knowledge about myopia!
“
01
Will myopia improve by sticking to no glasses?
Many parents believe that if myopia has not been wearing glasses, the degree will not develop and the vision will be improved. This idea is incorrect. In principle, if the child is short-sighted, the naked eye vision is poor, it is necessary to wear glasses; if the naked eye vision is better, myopia below 100 degrees, you can temporarily do not wear glasses, regular observation; for children with myopia above 100 degrees, you must wear glasses.
If myopia insists on not wearing glasses, it will accelerate the development of myopia. Children's eye adjustment ability is very strong, myopic children do not wear glasses, when looking far blurred, will use their own adjustment ability to see distant objects, if this for a long time, will lead to visual fatigue, dry eye, and will accelerate the progression of myopia.
02
Are myopic glasses really getting bigger and bigger?
Many parents have a misunderstanding that the more myopia glasses are worn, the greater the degree. In fact, the increase in the degree of myopia is not caused by wearing glasses, but by the growth of the eye axis caused by long-term close-up use of the eyes, and eye fatigue. Myopic glasses can provide a clear field of vision for myopic children, reduce visual fatigue, and slow down the development of myopia to a certain extent.
03
With myopic glasses, should the degree be small or small?
Some parents are worried that their children's myopia is too large, and they like low-level glasses when dispensing glasses. This is wrong. The principle of dispensing glasses is to choose the lowest degree when you can see clearly. The premise of this clear vision is to achieve 1.0 vision, at this time, the adjustment of the eyes is the most relaxed, and the vision is also the most comfortable. If the vision can not meet this standard, it will pay more attention to fatigue, resulting in the further development of myopia.
04
What are the correct ways to alleviate myopia?
For children without myopia, the internationally recognized method is to increase the time of outdoor exercise, 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 taken for prevention and control, such as the use of orthokeratology or low-concentration atropine eye drops, but each method also has its limitations, and it should also be combined with its own situation and listen to the advice of professional doctors.
05
Myopia does not need to be controlled, can I just do a laser surgery?
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 bleeding, and retinal detachment, and has become the primary factor causing blindness. Therefore, the prevention and control of myopia in adolescents is very necessary. Laser surgery for the treatment of myopia is very mature and safe, but it is only equivalent to making a pair of glasses on the surface of the eye, and can not improve the condition of the fundus, so it can be understood that surgery only helps us remove the glasses, not cure myopia.
06
Can myopia be cured?
At present, myopia is incurable, once it is determined that it is true myopia, what we can do is to control its development as much as possible and avoid further increasing the depth number and causing fundus lesions. Neither laser surgery nor crystal surgery can change the condition of the fundus, so that there is no fundamental cure for myopia.
