People often ask what to do if a child is nearsighted. My answer is, of course, standardized pupil dilatation, shadow testing, optometry, prescription glasses, wearing glasses is the treatment of myopia. However, some parents feel that wearing glasses has various disadvantages, such as the eyes will become convex after wearing glasses; wearing glasses will deepen the prescription; wearing glasses will become dependent afterwards, etc. Myopia is mostly due to the growth of the eye, the deeper the degree, the longer the eye, the longer the eye will be easier to abnormal convexity, glasses are innocent; said wearing glasses will deepen the degree, that do not wear glasses degree is also the same will deepen ah, glasses can not just become cannon fodder; myopia deep, wear glasses clear, of course, will be more accustomed to wear, if not wear, all day mimi eyes to see things is not desirable. Now is not to spit these, mainly to assume that children do not wear glasses will be how? Glasses need to be adjusted to look at the near place (about the adjustment see my science “myopia will not be presbyopia?”) The adjustment is accompanied by an inward turning of the eye and a narrowing of the pupil. As for the pupil narrowing, it is not relevant to the topic at hand, so I will not expand on it. The eye relaxes when looking at a distance, accompanied by an outward transmission of the eye and a dilated pupil. As a result, the eye turns inward when looking close and travels outward when looking far. When you are nearsighted, it is fine to see clearly up close, but it is blurry when you look far away. At this point, the brain reflexively thinks that the eyes are not relaxed enough and sends signals to make the eyes relax and try to see as far as possible, which is accompanied by an external rotation of the eyeballs. Although the human eyes are symmetrical, they are like the left and right hands, which are symmetrical but will manage to use the right hand. The same is true for the eyes, there will be one eye that is more habitual, and this habitual eye is called the primary eye. In a state of prolonged over-stimulation of the external rotation of the eye, the non-dominant eye is prone to emmetropia. Therefore, myopic people are prone to emmetropia, but most of them are invisible emmetropia, and the treatment for emmetropia is to wear the right number of glasses. Most people with strabismus have poor stereopsis, and what is the use of stereopsis? It is important to judge the distance, which is very important for outdoor activities, if the ground is uneven with poor stereopsis, it is not easy to find, and easy to fall; the object is not able to take the distance, easy to hit, such people are very dangerous if they drive on the road, road kill is not good for others and themselves. If there is a strabismus did not pay attention to the outward slant of the glasses will be easily inhibited, the brain will not use this eye, which will develop into strabismic amblyopia. This amblyopia is also to wear glasses to treat. I didn’t want to wear glasses, fishing to this point or have to wear, and also suffer, suffer not only, the effect is not necessarily so good. Well, this may sound extreme, but it is not uncommon in the strabismus department. When you think about it, myopia still needs to be corrected, and wearing glasses is a good way to do it at a good price.
