What is a short-sighted error ?

1 Answer

Answer :

Answer : Myopia is one of the 4 major diseases of the eye . This is actually the state of the eye when the light coming through the eyeballs does not fall on the retina of the eyeball and converges at a point somewhere in front of it. As a result, an image of an object more than 25 cm away from the eye is formed in front of the retina. As a result, a clear reflection of the object is not formed and it is not possible to look good. This is why myopia is also called "myopia". Other names include "short-sightedness" and "short-sightedness".
