Hyperopia

Hyperopia or Farsightedness is a type of vision in which seeing is clearer at far distances than at near. When the eye is relaxed, the combined powers of its optical elements is not enough to bring things into focus. This is because the image of an object falls behind the retina, and is thus, out of focus. The cause of hyperopia is either the length of the eyeball is too short, or the power of the cornea is too weak. If a person has good focusing ability or just a little hyperopia, he may be able to maintain both clear distance and clear near vision. If, on the other hand, a person has poor focusing ability or a high amount of hyperopia, he cannot focus efficiently even for far vision. This person's vision will be blurred for both distance and near, although greater for near. The hyperopic patient will have even more problems with near as he becomes presbyopic.

Plus lenses are used to correct hyperopia. It brings the image of an object forward, focusing on the retina, resulting in clear vision. In Asia, there are less hyperopes than there are myopes.
