What is Astigmatism
                     What is Astigmatism ?
The clear saucer-like tissue in front of the eye is called the
cornea and it is responsible for focusing the light waves into
the eyes. It is like a round shaped half of the basketball
normally. The even curved nature of the cornea allows the
light to focus the object clearly.
However, when the curved nature is deviated in its
entire surface, it may cause blurriness or ghost images
around objects. So also it affects the vision of both
closely placed and distant placed objects. This
condition is corrected either by glasses or contact
lenses. Sometimes this is also corrected by refractive
surgery.
