What is Astigmatism?
Astigmatism is a common eye condition that affects how you see. It happens when the front surface of your eye, called the cornea, or the lens inside your eye, is not perfectly round. Instead, it has an uneven shape. Because of this, light does not focus evenly on the retina, which is the part of your eye that senses light. As a result, you may see blurry or distorted images. . Many people have some degree of astigmatism, but not all need treatment.
Common Symptoms of Astigmatism
Astigmatism symptoms can vary from person to person. However, some signs are more common. If you notice any of these, you may have astigmatism:

In most cases, astigmatism is present from birth. However, it can also develop later in life. For example, eye injuries or certain diseases can change the shape of your cornea.
