Farsightedness is having a harder time seeing object that are close than things that are far away.
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.
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.
- Aching eyes
- Blurred vision when looking at close objects
- Crossed eyes (strabismus) in some children
- Eye strain
- Headache while reading
Mild farsightedness may not cause any problems. However, you may need reading glasses.
Exams and Tests
A general eye exam to diagnose farsightedness may include the following tests:
- Eye movement testing
- Glaucoma testing
- Refraction test
- Retinal examination
- Slit-lamp examination
- Visual acuity
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.
When to Contact a Medical Professional
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:
- Severe eye pain
- Eye redness
- Decreased vision
