Hyperopia
In cases of hyperopia the refractive power is too low. The focus point of the ocular lens is behind the retina. Incoming rays of light not meet in one "picture point" on the retina.
The ocular eye can partly compensate hyperopia by adjusting to the near distance which, however, puts a lot of strain on the eye. It can put the sharp image of an object on the retina, but the eyes tire rapidly leading to discomfort and pain in the long run, e.g. headaches.
Hyperopia is corrected through spherical single vision lenses with plus-dioptric values.
