Astigmatism[1] is a common vision problem caused by an irregularly shaped cornea that prevents light from focusing properly on the retina, the light-sensitive surface at the back of the eye. The most common symptom is blurred or distorted vision at any distance. People with astigmatism may also have eye strain[2], headaches, squinting to try to see clearly, or eye discomfort.

People with a mild form of astigmatism may not notice any symptoms. Its important to note that some symptoms of astigmatism can be related to other eye problems. It is therefore essential to receive regular eye exams[3]. This is especially true for children, who may not realize anything is wrong with their vision.
