Dear student,
Astigmatism is an eye condition with blurred vision.The front surface of the eye (cornea) of a person with astigmatism is not curved properly - the curve is irregular.When light rays enter the eye they do not focus correctly on the retina, resulting in a blurred image. Astigmatism may also be caused by an irregularly shaped lens, which is located behind the cornea.
Hope this helps.
