Astigmatism
Astigmatism occurs when the cornea is curved unevenly, more like a football than a basketball. Light passing through an uneven cornea is not properly focused on the retina. Distance and close vision may both be blurry. Learn more about astigmatism symptoms, astigmatism diagnosis and astigmatism treatment at www.geteyesmart.org.
