Normal finding: Most people have astigmatism which is when the front of the eye is not a perfect sphere. With significant astigmatism, your uncorrected (without glasses or contacts) vision is blurred. So if you don't have blurred vision, you don't have significant astigmatism. If you do have blurred vision, your eye doctor can tell you if it is due astigmatism or another cause.
