Answers:
Astigmatism is when the eye is shaped such that light doesn't focus at a single point, but rather at two points!. To correct it, you basically need two different powers of prescription -- one to refocus the light from the one focal point, and the other for the other focal point!. The way we do this is to have one power in one direction (say, vertically) and the other perpendicular to it (say, horizontally)!.
The whole football-baseball analogy explains *why* you have astigmatism, but hopefully this will give you a better idea of what it means from a functional vision standpoint!.Www@Answer-Health@Com

Astigmatism is a condition where the cornea has an irregular shape that causes problems with vision!. The cornea, the clear covering of the lens and iris, serves as a protection to the eye and helps transmit light thru the eye!. The cornea is normally spherical in shape, but those with astigmatism may have their cornea more oval shaped!. This oval shaping causes light to scatter instead of focusing to a single point as it passes thru the cornea and results in blurred vision!.

If you've ever looked at the images produced but those wavy mirrors at carnivals, you'll have some idea of how astigmatism can distort your vision!.

Astigmatism is characterized by distortions in your field of vision, often noted as the blurring of lines!. Astigmatism is also a common cause of eyestrain and headaches, especially with prolonged reading or lengthy sessions at the computer!. Astigmatism causes blurring of your vision at all distances, so objects close up and even those far away will be blurred!. Often present at birth, astigmatism affects many people, although not all cases are severe enough to require corrective treatment!.
