Is there any connection between eyesight and myopia?

Abstract: in short, myopia refers to the diopter of the cornea, and vision refers to the ability of fundus retinal imaging. The same degree can have different vision. Similarly, the same vision can also have different degrees., Ms. Wang took her daughter from junior high school to the eye hospital to match glasses. The child measured the visual acuity chart of 0.3 and the degree of myopia of 200. Ms. Wang was very confused. Is this normal? Compared with the online vision conversion chart, it seems wrong. Is there a mistake in optometry?, When talking about the eyesight chart, many people will think that there is a certain relationship between eyesight and myopia, and will also ask the doctor how much to convert eyesight into myopia., First of all, “vision” simply means people’s ability to see things clearly. The quality of vision is judged by the distance of seeing things clearly. The good ones are 1.5, 2.0 and the poor ones are 0.1. There are many factors affecting vision, Eye inflammation can cause vision loss (trachoma, red eye disease, etc.); trauma can also cause vision loss; diseases such as crystal opacity, vitreous opacity and retinopathy can also cause vision loss; however, the vision loss of most young students is mostly related to close-up eye fatigue. Myopia generally refers to diopter. For the eyes, the most direct change of refraction is reflected in crystal In terms of the bending degree of the body, 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; The lens is equivalent to a convex lens, that is, it can adjust its bending degree according to its own needs to change the distance of the focus, so as to see the object clearly., In short, myopia refers to the diopter of the cornea, and vision refers to the ability of fundus retinal imaging. The same degree can have different vision. Similarly, the same vision can also have different degrees., Although the higher the degree of the same person in the same period, the worse the eyesight, there is no absolute relationship between eyesight and myopia, and it is even more out of proportion. Some myopia patients have a myopia degree of 300 degrees, and the visual acuity test chart is 0.2. Some myopia patients have only 400 degrees, and the visual acuity test is also 0.2. So, this is just a check standard., Don’t think that myopia can’t happen in the future because your child doesn’t have myopia now!,

when talking about the visual acuity chart, many people will think that there is a certain relationship between visual acuity and the degree of myopia, and will also ask the doctor how much the degree of myopia is converted from visual acuity.

first say “vision”, which simply means people’s ability to see things clearly. The quality of vision is judged by the distance of seeing things clearly. The good ones are 1.5, 2.0 and the bad ones are 0.1. There are many factors affecting vision, Ocular inflammation can cause vision loss (trachoma, red eye disease, etc.); trauma can also cause vision loss; diseases such as crystal opacity, vitreous opacity and retinopathy can also cause vision loss; however, the vision loss of most young students is mostly related to close eye fatigue.

Myopia generally refers to diopter. For the eyes, the most direct change in refraction 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; The lens is equivalent to a convex lens, that is, it can adjust its bending degree according to its own needs to change the distance of the focus, so as to see the object clearly.

in short, myopia refers to the diopter of the cornea, and vision refers to the ability of fundus retinal imaging. The same degree can have different vision. Similarly, the same vision can also have different degrees.

although the higher the degree of the same person in the same period, the worse the eyesight is, there is no absolute relationship between eyesight and myopia, and it is even more out of proportion. Some myopia patients have a myopia degree of 300 degrees, and the visual acuity test chart is 0.2. Some myopia patients have only 400 degrees, and the visual acuity test is also 0.2. So, this is just an inspection standard.

don’t think that myopia can’t happen in the future because your child doesn’t have myopia now!

don’t think you have to wear glasses for a lifetime because your child has myopia!
