Astigmatism is a common vision condition caused by an irregular curvature of the cornea or lens, leading to blurred or distorted vision. It affects how light is focused on the retina, resulting in multiple focal points.

Astigmatism results from an irregular shape of the cornea or lens rather than a perfect spherical shape.
This condition can cause both near and distant objects to appear blurry or wavy.
Astigmatism is often corrected using cylindrical lenses that compensate for the uneven curvature.
A combination of astigmatism with myopia (nearsightedness) or hyperopia (farsightedness) is common.
The severity of astigmatism is measured in diopters, and higher values indicate more significant irregularity.
