What is Hyperopia?
Hyperopia which is also known as farsightedness means that a person sees better at distance than near.
Causes for Hyperopia
In general people with hyperopia have smaller than normal eyes and flatter than normal corneas. Children are often born hyperopic but because their lenses are very flexible, they can focus out the hyperopia. They usually grow out of being hyperopic. If the person is more than a little hyperopic they may also be blurred at distance as well and need glasses. Many people confuse hyperopia as normal clear vision. This is actually called emmetropia (no prescription or objects are focused on the retina normally). Genetics does play a role in a person’s status of their vision.
Symptoms of Hyperopia
Blurred near vision
Crossed eyes (Children with crossed eyes many times are hyperopic and their focusing can cause their eyes to cross)
Eye strain (especially when reading)
Amblyopia is commonly associated with hyperopia
A refraction is done to determine the status of the eye. Plus lenses are required to clear the vision.
As ones reaches their forties many people find that their vision getting blurred. It is first their near vision followed by their distance vision. The eye many times becomes more hyperopic as one ages through their forties and fifties. They start out wearing reading glasses and later bifocals. As a person reaches their forties, the lens inside the eye loses its ability to focus for near and this is called presbyopia (not to be confused with hyperopia).
After an eye examination, the eye doctor may provide an eye glass prescription if there is enough hyperopia to warrant it. Contact lenses may be used. Conductive keratoplasty may be used to treat mild forms of hyperopia. Lasik can be done in some cases of hyperopia after the progression has stopped.
