Farsightedness (Hyperopia)

Farsighted individuals are able to see objects at a far distance sharply whereas objects at a close distance appear blurry.

Compared to the normal eye, the farsighted eye usually has grown too short. The refractive point of incoming light rays is behind rather than on the retina.

Eye glasses or contact lenses for correction of farsightedness usually have collective (convex) lenses with a correction value in "plus" diopter, for example +3.5 dptr.

Up to a certain age, farsightedness can be compensated by the natural lens of the eye. The lens is able to change its shape thereby increasing its refractive power (accommodation), which makes up for the decreased refractive power of the farsighted eye for distance vision. Farsighted individuals usually are able to see images at a distance well, even at an older age. Eyeglasses for younger people are needed only in severe cases of farsightedness. On the other hand, the inability to read (also called undefinedpresbyopia) occurs at a younger age.
