Farsightedness
(Hyperopia)
About 1 in 4 people in the U.S. have hyperopia or farsightedness, but
fortunately there are more ways to correct this eye disorder than ever
before. People with hyperopia or farsightedness have difficulty
focusing on objects close up, such as print in a book. More severe
hyperopia would also cause problems with seeing objects in the distance
clearly, such as highway signs. The occurrence of hyperopia
increases with age; At least half of all persons over the age of 65 have
some degree of farsightedness.
What Causes It?
Hyperopia is a refractive error, like astigmatism and nearsightedness
(myopia). Having a refractive error means that light rays bend incorrectly
into your eye to transmit images to the brain. Farsightedness occurs when
light entering the eye focuses behind the retina, instead of directly on
it. An abnormally flat cornea or short eye can cause the light to enter
the eye this way. Hyperopia often runs in families. It is often
present at birth; however, many children outgrow it.
What Are the Symptoms of Farsightedness?
Symptoms of farsightedness may include:
* Headaches
* Eye strain
* Difficulty concentrating or focusing on nearby objects
* Fatigue or headache after performing a close task such as reading
If you experience these symptoms of hyperopia while
wearing your glasses or contact lenses, you may need a new prescription.
How Is Farsightedness Diagnosed?
Farsightedness can be easily diagnosed by a basic eye exam given by Dr.
Lampert or Dr. Sheiner.
How Is Farsightedness Corrected?
To correct hyperopia you must change the way the light rays bend when
entering your eye. Glasses, contact lenses, or refractive surgery can all
be used to correct farsightedness. Depending on the extent of your
farsightedness, you may need to wear your glasses or contact lenses at all
times, or only when you need to see objects up close, like when reading or
sewing. With hyperopia, your prescription is a positive number, such as
+3.00. The higher the number, the stronger your lenses will be.
