Astigmatism is a condition that results in blurred, unfocused, or fuzzy vision. The cornea (the front surface of the eye) or lens (located behind the cornea) has an abnormal or irregular curve.
There are two common types of astigmatism:
- Corneal astigmatism—misshapen cornea
- Lenticular astigmatism—misshapen lens
