Myopia

picture showing MyopiaNearsightedness (myopia) is a very common vision condition that affects nearly 30 percent of the Indian population.

It normally first occurs in school age children. Since the eye continues to grow during childhood, nearsightedness generally develops before age 20.

An individual that has myopia has trouble seeing clearly at a distance. With myopia, the center of the cornea is thinned. The thinned cornea corrects the
blurred vision from myopia, weakening the near sighted (too strong) eye. The rays (of light) entering the eye are bent too much, and focus ahead of the
retina, which is the normal focusing point.

After compressing, the rays spread out again, becoming scattered by the time they reach the retina, thus causing blurry vision.

Symptoms of myopia include:

Dangers

There is a slight danger of sight loss since the deformation of the eye creates stress on the retina which can become damaged or detached and can also provoke
other changes. This is especially the case in high myopia.
