Astigmatism is a defect in the eye or in a lens caused by a deviation from spherical curvature, which results in distorted images, as light rays are prevented from meeting at a common focus. Simply meaning your eye’s cornea or lens has an imperfection in its shape and the light coming in is not bent or refracted correctly. The cornea fails to focus the light equally on the retina leading to blurred or distorted vision.
