What Is Hyperopia?
Mr Glenn Carp – “In hyperopia, the focal point of the eye is behind the retina. So when light enters the eye it is focused to a point that is behind the retina and therefore the patient experiences blur. In these patients, the physical difference is that they may either have too short an eye, hence the focal point behind the retina, or that the corneal curvature is very, very flat and in the process the light is unable to be focused tight enough to reach the retina itself.”
Hyperopia Explained Further…
Hyperopia, often called long-sightedness, results from a disorder rather than from a disease. In hyperopia, the eyeball is slightly shorter and fatter than the eye’s lens requires, so that the point of focus is not directly on the retina (where the image is formed), but at a point some way behind it.
As a result, hyperopia sufferers can see distant objects well, but have difficulty focusing on objects that are near. Sufferers of mild hyperopia can often sharpen the image of close objects by making a conscious effort to focus and hyperopia may therefore lead to headaches.
Hyperopia is a relatively common condition affecting about one in every four people. People usually inherit hyperopia, and nearly all babies actually start life hyperopic – this hyperopic condition lessens as they grow.
