Eye Info: Astigmatism |
 |
Astigmatic Eye
Astigmatism
is that condition wherein the refraction varies in different
meridians of the eye. It occurs when light entering the
eye is "split" into two separate parts instead of focusing
on one precise point on the retina. Astigmatism is commonly
caused by abnormalities in the curvature of the cornea.
If you are astigmatic, you will experience a distortion
or blurring of images at all distances, nearby as well as
distant.
Symptoms of Astigmatism
Astigmatism may cause blurred vision, eyestrain
or even headaches. It can also cause images to appear doubled,
particularly at night.
