Astigmatism

Astigmatism is a common eye condition that affects how your eyes focus light. It can cause blurry or distorted vision.

What is astigmatism?

Astigmatism happens when the front part of the eye, called the cornea, is not perfectly curved. Instead of being shaped like a basketball, it may look more like a rugby ball. This irregular shape prevents light from focusing evenly on the retina, leading to vision problems.
