| What is astigmatism? |
| Astigmatism is a condition that occurs when the cornea or lens is steeper in one axis than another, similar to a football or the back of a spoon instead of completely spherical or round like a basketball. Light entering the cornea focuses on more than one point within the eye resulting in blurring vision. Astigmatism is either regular when steep and flat axes are 90 degrees apart or irregular when they are not separated by 90 degrees. |
