Although there is no direct scientifc evidence for it, some feel. Hyperopia frequently occurs when an eye is shorter than normal from front to rear; the lens is then unable to increase its convexity sufficiently to focus the images of close objects onto the retina. Corrective lenses for hyperopia are designed to supply the additional convexity needed for focusing.

This is a common anomaly associated with vision. When a laser is used to treat myopia, it gently flattens the contour of the cornea, which lessens its focusing power and allows light to focus farther back, directly on the retina.

Imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: myopia, hyperopia and astigmatism. Combinations of astigmatism myopia hyperopia and astigmatism astigmatism myopia hyperopia hyperopia astigmatism myopia hyperopia astigmatism are common.
Presbyopia may occur in a person with good distance vision or with any of the other refractive errors astigmatism, myopia and hyperopia. It is often incorrectly referred to as long- sightedness because some long- sighted patients also only require reading glasses.
What are the symptoms? Presbyopia is a natural part of the ageing process.

During the exam the Optometrist will perform several tests — such as a visual field test, a visual acuity test, and an autorefractor test — that will indicate the presence of hyperopia. A very good and pertinent question!
For this you have to step back in time, thousands to millions of years ago into evolution of man. When humans were in the wild, their use of the eyes was similar to that of wild animals, needing to focus on dist. Hyperopia far-sightedness is due to a shortened eye, so the focal point falls behind the retina.

Again, this can be corrected by a lens, this time a convex one Fig. These refractive errors can also be caused by the corneal surface being either too curved myopia or too astigmatism myopia hyperopia hyperopia.

The conservative treatment of hyperopia includes the prescription of graded lenses glasses and the use of contact lenses. The early use of corrective glasses and contact lenses in the treatment of hyperopia in children reduces the temporal risk for advanced age myopia [6].
For corneal imperfections, refractive surgery may be applied to correct vision. In myopia, a person is not able to see distant objects clearly.
Myopia also referred to as Nearsightedness is a common vision in which you can see objects near to you clearly, but objects farther away are blurry.
In hypermetropia, a person is not able to clearly see the nearby objects. In this defect, lens are astigmatism myopia hyperopia able to produce astigmatism myopia hyperopia image of the distant objects on the retina instead the image is formed in front of the retina. What Causes Hyperopia? Hyperopia occurs when light entering the eye is focused behind the retina, rather than directly onto it. This focal abnormality occurs when the eyeball is too short and results in blurred near vision.
Like myopia, hyperopia can present at a young age. In hyperopia people have difficulty in seeing near objects but can see the far objects clearly whereas in myopia people who have difficulty in seeing distant objects but can see near objects clearly.
