WHAT Is Astigmatism?
Labels Astigmatism
Astigmatism (a-STIG-ma-tiz-um) is an eye condition that causes objects
to appear blurry because the front part of the eye is misshapen.
The eyeball usually is round and nearly the same size as a ping-pong ball.
The front part contains a clear layer of tissue called the cornea and the
lens that help to focus the light that enters the eye. When people have
astigmatism, the cornea and/or the lens is misshapen, and their curved
surfaces are unequal. If the curve is just slightly off-shape, only objects
at a distance may appear blurry. People with more serious astigmatism,
however, may experience a distortion of all images.
