hyperopia

 [hi″per-o´pe-ah]
a defect of vision in which parallel light rays reaching the eye come to focus behind the retina, vision being better for distant objects than for near. Called also farsightedness.

Most children are born with some degree of farsightedness. As the child grows this decreases and usually disappears by the age of 8 years. If the child is excessively farsighted, however, the constant effort to focus may cause headaches and fatigue. Eyeglasses used to correct hyperopia are convex; that is, they bend the light rays toward the center, helping the lens of the eye to focus them on the retina.

Patient discussion about farsightedness

Q. Is there a laser vision correction operation that will correct both near and farsightedness? My optometrist said that typical laservision would require that I wear glasses for reading since it only corrects farsightedness. I'm leery of the technique of doing only one eye for distance and leaving the other "as is" for reading. I seem to recall a brief news report of some new laser vision technique that corrects both near- and farsightedness. Is that true or were they referring to the "one eye for closeup and one eye for distance" type of correction that I'm skeptical about? Thanks!!

A. my mother-in-law had that done about a yeara ago,for both near and far,they make them the oppisite,i had my near sightness fixed two years ago and i love it should of done it sooner.....
