Definition

People with farsightedness (hyperopia or hypermetropia) usually have difficulty seeing close objects. In severe cases, they can have trouble seeing objects both far and near.

Causes

Farsightedness is a type of refractive error, which means the shape of the eye does not bend light correctly, so images are blurred. In farsightedness, the eyeball is too short for light rays to clearly focus on the retina. It may also be caused by a problem with the shape of your cornea or lens.
