This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. Hypermetropia, or Hyperopia or farsightedness, is a common vision problem, affecting about a fourth of the population. People with Hypermetropia usually can see distant objects clearly, but have difficulty focusing on objects that are up close.
The eyeball of a farsighted person is shorter than normal. New borne are usually hypermetropic, and some of them "outgrow" it as the eyeball lengthens with normal growth. Sometimes people confuse hyperopia with presbyopia, which also causes near vision problems but for different reasons.
Farsightedness can be corrected with glasses or contact lenses to change the way light rays bend into the eyes. You may need to wear your glasses or contacts all the time when reading, working on a computer or doing other close-up work. Refractive surgery, such as LASIK , is another option for correcting hyperopia. Surgery may reduce or eliminate your need to wear glasses or contact lenses.
