Astigmatism axis

**Astigmatism Axis**

The “Astigmatism axis” refers to the specific orientation of the cylindrical correction needed to address astigmatism in the eye. Astigmatism is a common vision condition caused by an irregularly shaped cornea or lens, leading to blurred or distorted vision. The axis is measured in degrees, ranging from 0 to 180, and indicates the direction of the astigmatism correction required in an eyeglass or contact lens prescription. Understanding the astigmatism axis is essential for accurate vision correction and improved visual clarity.
