Question

What causes myopia and hypermetropia

Answer 1

$\huge\textbf{Answer}$

Causes of Myopia
--------------------------------

☆Nearsightedness also can be caused by the cornea and/or lens being too curved for the length of the eyeball.

☆In some cases, myopia is due to a combination of these factors.

☆Myopia typically begins in childhood and you may have a higher risk if your parents are nearsighted.

Causes of Hpermetropia
------------------------------------------

☆Hyperopia develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision.

☆This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina.

☆It may also be caused by an abnormal shape of the cornea or lens.
