Farsightedness is having a harder time seeing objects that are close than things that are far away.
The term is often used to describe the need for reading glasses as you get older. However, the correct term for that condition is presbyopia. Although related, presbyopia and hyperopia (farsightedness) are different conditions. People with hyperopia will also develop presbyopia with age.
Farsightedness is the result of the visual image being focused behind the retina rather than directly on it. It may be caused by the eyeball being too small or the focusing power being too weak. It can also be a combination of both.
Farsightedness is often present from birth. However, children have a very flexible eye lens, which helps make up for the problem. As aging occurs, glasses or contact lenses may be needed to correct the vision. If you have family members who are farsighted, you are also more likely to become farsighted.
Mild farsightedness may not cause any problems. However, you may need reading glasses sooner than people who do not have this condition.
A general eye exam to diagnose farsightedness may include the following tests:
This list is not all-inclusive.
Farsightedness is easily corrected with glasses or contact lenses. Surgery is available for correcting farsightedness in adults. This is an option for those who do not wish to wear glasses or contacts.
The outcome is expected to be good.
Farsightedness can be a risk factor for glaucoma and crossed eyes.
Call your health care provider or eye doctor if you have symptoms of farsightedness and you have not had a recent eye exam.
Also, call if vision begins to get worse after you have been diagnosed with farsightedness.
See a provider right away if you think you have farsightedness and you suddenly develop the following symptoms:
