Also called farsightedness. Far away objects are easier to see than near ones.

The extra effort to see up close can produce blur, fatigue, headaches, and eye muscle strain. In those situations glasses can help.

Causes

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, but children have a very flexible eye lens, which helps make up for the problem. As aging occurs, glasses or contact lenses may be required to correct the vision. If you have family members who are farsighted, you are also more likely to become farsighted.

Symptoms

  • Aching eyes
  • Blurred vision of close objects
  • Crossed eyes (strabismus) in some children
  • Eye strain
  • Headache while reading

Mild farsightedness may not cause any problems except for a need for reading glasses.

Treatment

Farsightedness is easily corrected with glasses or contact lenses. Surgery is available for correcting farsightedness in adults, and can be used for those who do not wish to wear glasses or contacts.

Possible Complications

Farsightedness can be a risk factor for glaucoma and crossed eyes.
