People who can see clearly at short distances but have trouble focusing on objects far away may have myopia. A common condition that generally starts during childhood, it is easy to treat myopia; though well-understood, research continues into the condition and has led to new insights.

1. What is Myopia?

Myopia is an eye condition that causes poor long-distance vision. It is also known as nearsightedness because myopic people can still clearly see things that are close. Structural irregularities in the eye cause the condition. In myopic eyes, the eyeball is longer than normal, or the cornea is too thick or too curved. This means the light is focused in front of the retina rather than on the retina, causing some images to be blurry.
