Farsightedness, or hyperopia

This is a focusing problem caused by an eyeball that is shorter than normal. Due to the reduced length, the lens fails to bring light rays to a focal point by the time they reach the retina. The effects of farsightedness vary with age because of the diminishing flexibility of the lens. Young people may not notice any effects. But as the eyes begin to age, near objects become increasingly difficult to see. Later in life nearly all focal ranges may be unclear. Farsighted people need to use plus powered spectacles to see clearly.
