Hyperopia, also known as farsightedness, is a common type of refractive error where distant objects may be seen more clearly than objects that are near. However, people experience hyperopia differently. Some people may not notice any problems with their vision, especially when they are young. For people with significant hyperopia, vision can be blurry for objects at any distance, near or far.
Signs and Symptoms of Hyperopia
Farsighted people sometimes have headaches or eyestrain, and may squint or feel fatigued when performing work at close range. If you get these symptoms while wearing your glasses or contact lenses, you may need an eye exam and a new prescription.
What Causes Hyperopia?
Farsightedness occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is often shorter than normal.
Many children are born with hyperopia, and some of them "outgrow" it as the eyeball lengthens with normal growth.
Depending on the amount of farsightedness you have, 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 PRK, is another option for correcting hyperopia.
