If high myopia is not accompanied by discount prescription glasses, the eyeballs will also deform. Eye deformation is caused by the elongation of the visual axis and the protrusion of the eyeball after the degree of myopia deepens. This is a problem with the eyes themselves and has nothing to do with wearing glasses.

If the eye is compared to an optical instrument, the distance from the outermost cornea where the eye receives light to the innermost retina where the light is felt can be regarded as a central axis of the optical system, namely the eye axis.

Do you see it? Do you understand? The deformation of the eyes is only related to the degree and has nothing to do with the eyeglasses online. If you have to blame it, then you should also blame your eyesight. So, everyone should take good care of their eyes and try to control the increase in eye strength, in order to minimize eye deformation.

Do not wear glasses for nearsightedness, as the degree will increase as you wear them. This sentence is spoken the most from parents, especially those who wear childrens glasses for the first time, and even many people who are already nearsighted hold this concept. In fact, if one is nearsighted and does not wear glasses, the degree will increase even faster!

If you are nearsighted but insist on not wearing glasses, there are two consequences. One is that you cannot see distant targets clearly, and you have a habit of squinting your eyes, frowning, and looking at things, which can easily cause visual fatigue. The second is to squint your eyes into a slit when looking at objects. Over time, the upper and lower eyelids may compress the eyeball, which may lead to astigmatism.
