Nearsightedness (myopia) is a very common condition in which the light coming into the eye is not focused properly onto the retina, making it difficult to see objects far away. ... Farsightedness (hyperopia) is the opposite of myopia, and is usually caused by shortening of the eyeball.

MYOPIA ALSO CALLED AS NEARSIGHTEDNESS
objects that are at a distance or nearby can be focused by the human eye due to its abilities. To watch objects that are nearby and focus on them the lens of the eye has a short focal length. If the curvature of the lens is large it will be able to focus on closer objects whereas if the curvature is small it will be able to focus on objects further far away. Most of the time, the effects of the defect start showing up at the extreme ends of the visual spectrum.
HYPEROPIA ALSO CALLED AS FARSIGHTEDNESS and sometimes called hyperopia
A refractive error in which distant objects are clearly seen, but close objects appear blurry. People experience farsightedness differently, and some people, more commonly when they are young, do not notice any problems with their vision. In addition, for people with significant farsightedness, vision can be blurry for objects at any distance, near or far.
