Technically known as hyperopia, farsightedness occurs when the eye is shorter than normal. This shape causes images to be focused behind the retina rather than on it. The condition is usually inherited.
What causes farsightedness?
Contrary to what the name implies, people who are farsighted have blurred vision at all distances—unless they make a constant effort to focus, which can lead to strain, headaches, and eye fatigue. In fact, babies and children are usually slightly farsighted; as their eyes grow and lengthen, the condition corrects itself, generally by age seven or eight. However, some young people who remain farsighted are unaware of it, because they have enough flexibility in their focusing power to correct the condition without the aid of eye glasses or lenses.
How is farsightedness corrected?
People who are farsighted can have their vision corrected by glasses or contact lenses.
