Your eye relies on the cornea—the clear, front window of your eye—to bend light so you can see clearly. In a healthy eye, the cornea is perfectly round like a basketball, allowing light to focus evenly on the back of the eye.
With astigmatism, the cornea or the lens inside the eye is curved unevenly, like a football. Because of this irregular shape, light gets bent in different directions as it enters the eye, which prevents it from focusing on a single point. This results in vision that looks blurry or stretched at all distances.
Common Symptoms

- Squinting frequently to try and see things more clearly.
- Eye strain or feeling like your eyes are tired after reading or using a computer.
- Headaches, especially after tasks that require focusing your eyes.
