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 lens within their eye, which helps make up for the problem. Most children outgrow the condition. 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.
