Farsighted Vision (Hyperopia)

  • farsighted vision also known as Hyperopia, is an eye condition where a person has difficulty seeing objects closer to the eye, but the ability of seeing far away is good.
  • Its an inherited vision, thats caused by an abnormally short eye.
 
Hyperopia, also called farsightedness, is a condition in which a person has difficulty seeing objects that are located close to the eye, although vision of distant objects (that is, far vision) is good.
In most cases, farsightedness is an inherited condition that is caused by an abnormally short eye, as measured from front to back. This situation reduces the distance between the cornea (the clear film that covers the front of the eye) and the retina (the light-sensitive layer at the back of the eye). As a result, images tend to focus behind the retina, rather than on the retina itself. Sometimes, the eye is able to partially or totally compensate for this focusing problem through a process called accommodation. In accommodation, tiny ciliary muscles within the eye contract, altering the shape of the lens and bringing the viewed object into focus.
