Hyperopia (forsightedness) is a common vision problem in which you can see distant objects clearly, but objects near to you are blurry.
Hyperopia is vision defect caused by an imperfection in the eye (often when the eyeball is too short or when the lens is not round enough), causing an inability to focus on near objects. In extreme cases, it can cause the inability to focus on objects at any distance.
As an object moves toward the eye, the eye must increase its power to keep the image in focus on the retina. If the power of the cornea and lens is insufficient, as in hyperopia, the image will appear blurred.
In addition to blurry vision, people with hyperopia can experience headaches and “eye strain”, focusing difficulty, amblyopia (“lazy eye”) and crossed eyes.
Hyperopia is often confused with presbyopia, another condition that frequently causes blurry near vision. Presbyopes who report good far vision typically experience blurry near vision because of a reduced accommodative amplitude brought about by natural aging changes with the crystalline lens. (It is also sometimes referred to as farsightedness, since in otherwise normally-sighted person,s it makes it more difficult to focus on near objects than on far objects.)
Symptoms are primarily poor or uncomfortable near vision. However, the blurry vision can extend to distance vision as well with age, or if the hyperopia is severe enough.
This condition can be treated with glasses, contact lenses, or refractive surgery (i.e. LASIK).
