Astigmatism is one of the most common refractive errors. Similar to other body parts like ears, legs or feet, the clear surface which is called cornea of the eyeball is not 100% symmetrical but slightly shaped similar to a rugby ball (toric in shape) or in some cases has an irregular shape in general from birth or after an injury. Simply put, the need for correction is for some areas of the eye stronger than for the rest of the eye.
