True and false myopia

Abstract: when it comes to true myopia and pseudomyopia, we have to mention an important part of our eyes – ciliary muscle. In fact, the ciliary muscle is equivalent to the focusing function of the camera. When we look far away, it relaxes. After relaxation, the lens becomes thinner and the light focuses on the retina;

what is true myopia and false myopia?

and

true myopia: the axis of the eye becomes longer and imaged in front of the retina, resulting in blurred vision.

pseudomyopia: pseudomyopia is not myopia in essence, but continuous contraction and spasm of ciliary muscle, increase of lens thickness and blurred vision due to excessive use of eyes.

how do true myopia and false myopia form?

when it comes to true myopia and pseudomyopia, we have to mention an important part of our eyes – ciliary muscle. In fact, the ciliary muscle is equivalent to the focusing function of the camera. When we look far away, it relaxes. After relaxation, the lens becomes thinner and the light focuses on the retina; As you look closer, it contracts and the lens thickens, which is equivalent to a convex lens that focuses the image of the object on the retina. The difference between

and

pseudomyopia and true myopia lies in the contraction and relaxation of ciliary muscle: pseudomyopia is a reversible process. Ciliary muscle can’t relax for a while, but it can relieve eye fatigue through drug or physical relaxation. After a period of rest, ciliary muscle relaxes and can be adjusted normally. This is a state of pseudomyopia. True myopia is an irreversible process. The ciliary muscle is too tired, the eye axis grows too much, and drugs or other methods can’t recover. This is true myopia. If you don’t pay attention to using your eyes, pseudomyopia will also evolve into true myopia.
