Definition

People with farsightedness have a hard time seeing close objects. Images are blurred. People with severe symptoms may have trouble seeing objects both far and near.

Causes

This problem happens when the shape of the eye does not bend light correctly. 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 the cornea or lens.
