What is Astigmatism?
Many people struggle with clear vision. Astigmatism is a common eye condition that can cause blurry or distorted sight. In simple terms, astigmatism happens when the front surface of the eye, called the cornea, is not perfectly round. Instead, it has an uneven shape.

According to the American Academy of Ophthalmology, astigmatism affects millions of people worldwide. If you have trouble with clear vision, astigmatism could be the reason.
