Refractive Errors

Refractive Errors

Refractive errors of the eye are seen in 20 percent of children and have been found to run in families. The most common refractive errors are astigmatism, hyperopia (farsightedness) and myopia (nearsightedness).

Astigmatism

Astigmatism is a condition in which an abnormal curvature of the cornea can cause two focal points to fall in two different locations, making objects up close and at a distance appear blurry.

Hyperopia

Hyperopia is a condition in which an image of a distant object becomes focused behind the retina, making objects up close appear out of focus.

Myopia

Myopia is a condition in which, opposite of hyperopia,an image of a distant object becomes focused in front of the retina, making distant objects appear out of focus.
