Parents think: correction is the cure, see here, are you going to say: is not it right? I have always thought so, vision correction is not good! To explain this, we need to talk about the “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 bag of French fries on the table, because the French fries pass through the refractive system of the eye, and the image is accurately presented in the bottom of the eye. Then there are inaccuracies, that is, the refractive system is not well aimed, can only present a clear image in the eye before the bottom of a position, but not to the bottom of the eye, we naturally can not see the bag of fries, of course, does not prevent us from taking it over and eat it. This is what we call “myopic” refractive error, or nearsightedness. Refractive correction What is refractive correction? Correction is the process by which an image that cannot be accurately visualized in the eye is adjusted and moved to a specific position in the eye so that the image can be seen clearly. However, correction is only a modification of the focusing state of the refractive system of the eye, and does not change the structural characteristics of the refractive system itself. Just as a person who is short in height can wear high heels and immediately become taller and more upright, however, 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, it can promote the normal development of visual function (including visual acuity, stereopsis, etc.), and avoid and block the role of undesirable external factors that contribute to the deepening of refractive error.
