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.
