What is Astigmatism?
Astigmatism is a common vision condition where the cornea or lens is irregularly shaped, causing blurred or distorted vision at any distance.

How Cylindrical Lenses Correct Astigmatism
In astigmatism, the eye's curvature is uneven, causing light to focus at multiple points. Cylindrical lenses are used to focus light on a single point on the retina, eliminating blur and distortion for clearer vision.
