Explanation:
Detailed explanation-1: -Astigmatism is an irregularly shaped cornea or lens that prevents light from focusing properly on the retina, the light-sensitive surface at the back of the eye. The surface of the cornea is shaped more like a football instead of round like a basketball and the eye is unable to focus light rays to a single point.
Detailed explanation-2: -If you have astigmatism, light that enters your eye bends unevenly.
Detailed explanation-3: -What causes astigmatism? Astigmatism happens when your cornea or lens has a different shape than normal. The shape makes light bend differently as it enters your eye, causing a refractive error. Doctors don’t know what causes astigmatism, and there’s no way to prevent it.
