Abstract: vision is different from the degree of myopia. The same degree can have different vision. Similarly, the same vision can also have different degrees. Although the deeper the degree of the same person in the same period, the worse the eyesight, there is no absolute relationship between eyesight and myopia., When many parents check that their children’s eyesight is bad, they will ask: is my child’s eyesight serious? How many glasses should I wear? It is generally believed that there is a certain relationship between vision and myopia, so parents want to convert vision into myopia?, In fact, vision and myopia are two different concepts. First of all, “vision” means people’s ability to see things clearly. The good or bad vision is judged by the distance of seeing things clearly. The good ones are 1.2, 1.5 and the poor ones are 0.1. Immediate defense Light sense (that is, you can’t see clearly and can only feel the presence of light). There are many factors affecting your vision. Inflammation can cause vision loss; trauma can also cause vision loss; diseases such as crystal opacity and retinopathy can also cause vision loss; most of the vision loss of young students is mostly related to close-up eye fatigue. In addition, the degree of myopia is one Generally refers to diopter. For the eyes, the most direct change in diopter is reflected in the bending degree of the lens. The closer the visual object is, the greater the curvature of the lens is. In terms of adjustment, it is more laborious. In terms of self perception, it is eye fatigue. In fact, the lens is a convex lens, that is, it can adjust its bending degree according to its own needs, To change the distance of the focus to see the object clearly., Vision is different from the degree of myopia. The same degree can have different vision. Similarly, the same vision can also have different degrees. Although the deeper the degree of the same person in the same period, the worse the eyesight, there is no absolute relationship between eyesight and myopia., Some people are 600 degrees, and the visual acuity chart is 0.2. Some people are 400 degrees, and the visual acuity is 0.2. So, this is just a check standard.,

eyesight are different from myopia. The same degree can have different eyesight. Similarly, the same eyesight can also have different degrees. Although the deeper the degree of the same person in the same period, the worse the eyesight, there is no absolute relationship between eyesight and myopia.
some people have 600 degrees, and the visual acuity test chart is 0.2. Some people have 400 degrees, and the visual acuity test is also 0.2. So, this is just an inspection standard.
