Astigmatism

(En español: Astigmatismo)

Say: uh-stig-muh-tih-zum

If you take a good look at your eye, you might barely see your cornea, the clear outer covering of the eye. For someone with astigmatism, the cornea is uneven, which changes how light enters the eye and may make things look funny. Things may look blurry, like making the letter "D" look like a "B," or wavy, like looking in a funhouse mirror. But glasses will fix that problem in no time.
