Hyperopia
farsightedness is a vision condition in which distant objects are
usually seen clearly, but close ones do not come into proper focus.
Farsightedness occurs if your eyeball is too short or the cornea has
too little curvature, so light entering your eye is not focused
correctly.

vision screenings, often done in schools, are generally ineffective in
detecting farsightedness. A comprehensive optometric examination will
include testing for farsightedness.
In mild cases of
farsightedness, your eyes may be able to compensate without corrective
lenses. In other cases, your optometrist can prescribe eyeglasses or
contact lenses to optically correct farsightedness by altering the way
the light enters your eyes.
Hyperopia symptoms and signs
Common
signs of farsightedness include difficulty in concentrating and
maintaining a clear focus on near objects, eye strain, fatigue and/or
headaches after close work, aching or burning eyes, irritability or
nervousness after sustained concentration.
Hyperopia causes
This
vision problem occurs when light rays entering the eye focus behind the
retina, rather than directly on it. The eyeball of a farsighted person
is shorter than normal.
Many children are born with hyperopia, and some of them "outgrow" it as the eyeball lengthens with normal growth.
Sometimes people confuse hyperopia with presbyopia, which also causes near vision problems but for different reasons.
Hyperopia treatments
Farsightedness
can be corrected with glasses or contact lenses to change the way light
rays bend into the eyes. If your glasses or contact lens prescription
begins with plus numbers, like +2.50, you are farsighted.
You
may need to wear your glasses or contacts all the time or only when
reading, working on a computer or doing other close-up work.
Refractive
surgery, such as LASIK or CK, is another option for correcting
hyperopia. Surgery may reduce or eliminate your need to wear glasses or
contact lenses. Investigational procedures involving corneal inlays and
onlays may be a future option for correcting hyperopia.
