Hyperopia (Farsightedness)
The light rays are being focused onto the retina, the result is clear vision in all ranges.
The light rays from closer objects are focused behind the retina causing them to be blurred.
Also called farsightedness. Caused by the eye being excessively short (axial length) or the cornea being excessively flat, or both. It is possible to compensate for Hyperopia by using the eye’s built-in focusing system in a process called accommodation, so a farsighted person doesn’t usually complain of blurred vision. Hyperopia is a common cause of reading difficulties, especially involving tracking, and also causes asthenopia, or visually related discomfort.
It is common to use reading glasses with young hyperopes to assure smooth and efficient reading. The glasses are not used to make the images clear, but rather to relieve the stress caused by the near vision tasks that cause skipping, unstable clarity, the appearance of moving print, and other eye movement control problems brought on by hyperopia. The use of glasses instantly resolves the causes of eye movement control problems in Hyperopia.
Hyperopia isn’t likely to change over time, and the use of glasses does not cause it to go away. Surgical procedures for Hyperopia are less likely to be successful than for Myopia. Orthokeratology is not applicable to Hyperopia, but contact lenses are another option to the use of glasses.
