• Farsightedness or hyperopia is a refractive error (focussing error) that is corrected by glasses, contact lenses or LASIK.
  • It occurs when light entering the eye focuses behind the retina, instead of directly on it.
  • This is caused by a cornea that is flatter, or an eye that is shorter, than a normal eye.
  • Farsighted people usually have trouble seeing up close, but may also have difficulty seeing far away as well as they approach their forties.
