CAUSES OF ASTIGMATISM
Vision is effected by an irregular-shaped cornea.
When the cornea is perfectly round, light rays bend (refract) evenly onto a small area of the retina to create a sharp image. With astigmatism, the cornea (the clear, outermost layer of the eye) is oval. So the light is unable to focus, producing a blurred image.
Most people have some sort of astigmatism – it's very rare for the cornea to be perfectly round.
