Answer 2

Answer:

Astigmatism is an imperfection in the curvature of your eye’s cornea or lens. Normally, the cornea and lens are smooth and curved equally in all directions. This helps to focus light rays sharply onto the retina at the back of your eye. If your cornea or lens isn't smooth and evenly curved, light rays aren't refracted (bent) properly. Doctors call this a refractive error
