What is Myopia?

Myopia is a condition in which the eyes see clearly the objects nearby but can not clearly see the objects at the far end. The myopia word comes from the Latin "closed eye" word because myopia people shorten their eyes to see far better.


Myopia is often hereditary and occurs in children between the ages of 8 and 12 years. During my youth, myopia increases as the body grows and remains at a certain level in adult life. The most important factor affecting myopia is heredity, ie the presence of myopia in the family. Overeating, insufficient use of eyes or poor nutrition can cause myopia.


The cause of myopia is usually oval in appearance, and it is impossible for the eye lens to change its shape as far as focusing the rays from distant objects on the retina. Rarely, the cause of myopia is a change in the shape of the cornea or an alteration in the shape of the eye lens.


Almost all myopia has a simple myopia that increases with the growth of the body. Even if myopia increases, this is the result of normal growth. In the age of adulthood, the length of the eye changes as the body grows and it may require new glasses every 6 months. It is like taking big shoes that fit the growing feet. Myopia progresses rapidly for a few years and then changes very little. There are also adult-type myopia, which usually takes place between 20 and 40 years.
