This is not a drama, it is a conversation that happens countless times in hospital clinics, the problem is that parents think: correction is the cure, see here, you are not going to say: is not it right? I always thought so, vision correction is not good! To explain this problem, we have to talk about this “refractive error” and “correction” in the end what is the matter. Refractive error: refraction, refers to the refractive system of the human eye, we can see things clearly, such as a packet of fries on the table, because the fries through the refractive system of the eye, the image accurately presented in the fundus of the eye. Then there is accuracy and there is inaccuracy, that is, the refractive system is not aimed well. If the aiming area is forward, that is, focused in front of the retina, but not focused on the retina. This is what we call “myopic” refractive error, or “myopia”. Refractive correction: What about correction? It is the process of adjusting the image that is not accurately focused on the retina and moving it to the retina so that it can be imaged clearly. However, correction is only a correction of the focusing state of the refractive system of the eye, and does not change the structural characteristics of the refractive system itself. Just like a person who is short in height can put on high heels and immediately become tall and straight, but it does not make the body grow taller. Therefore, refractive correction is not a treatment for myopia. For developing children, with the help of appropriate correction, clear vision can be obtained, thus promoting the normal development of visual functions (including visual acuity, stereopsis, etc.), and avoiding and blocking the role of adverse external factors that contribute to the deepening of the degree of refractive error.
