Astigmatism

Astigmatism is a common vision problem caused by an irregularity in the curvature of the cornea (the clear surface at the front of the eye) or, less frequently, the lens (the lens inside the eye). In a normal eye, the cornea and lens are perfectly spherical, allowing light to focus sharply on the retina, at the back of the eye.

However, in a person with astigmatism, the curvature of the cornea or lens is irregular, similar to that of a football. This irregularity causes uneven refraction of light, meaning that light rays do not converge at a single focal point on the retina. Instead, they focus at multiple points, causing blurred or distorted vision at all distances.
