What is Myopia

[Lucysmith]

Myopia is a vision defect commonly known as nearsightedness. Those with myopia can see clearly up to a certain distance, then objects begin to appear fuzzy or out of focus.

Myopia, which is measured in diopters by the strength or optical power of a corrective lens that focuses distant images on the retina, has also been classified by degree or severity

* Low myopia
* Medium myopia
* High myopia

Some people who were born myopia can not regain their eyesight even they wear eyeglasses.

High myopia may cause the eyeball be out shape.
We must take good care of our eyes.
