It typically happens when the cornea or lens is shaped more like a football than a basketball. In regular astigmatism, the two main focusing directions (principal meridians) are at right angles to each other. It is commonly discussed in eye exams, glasses and contact lens prescriptions, and refractive or cataract surgery planning."}
