Many myopic people are still entangled, feeling that their eyes seem to become convex and ugly after taking off their glasses.

 

1. Will wearing glasses cause the eyeballs to become convex?

Myopia does cause bulging of the eyeball, but it is not caused by wearing glasses.

 

Myopia refers to the state of adjustment and relaxation, parallel rays refracted by the refractive system of the eyeball cannot be focused on the retina, and before focusing on the retina, a unclear image is formed on the retina.

 

 

2. How does myopia occur?

Due to the change of modern lifestyle, the close eye use time is long and the load is heavy, resulting in continuous contraction and spasm of the ciliary muscle, the lens cannot be relaxed, and the adjustment is unbalanced.

 

For example, the adjustment of the ciliary muscle is like a "spring", excessive use of the eyes will make the ciliary muscle too tight, so that it has been in a state of high tension and continuous contraction, the elasticity of the "spring" will become worse, and it cannot be relaxed when looking far, so in the long run, the face slowly becomes "pseudomyopia", and then becomes true myopia.

 

If it is allowed to develop, various factors that make eye fatigue cannot be alleviated, the ciliary muscle continues to contract and spasm, resulting in a lag in adjustment, the length of the eye axis will continue to grow, the degree of myopia will increase, and it will slowly evolve into high myopia.
