Astigmatism is a common refractive error in the eye caused by an irregular shape of the cornea or lens, leading to blurred or distorted vision. Instead of being evenly curved, the cornea or lens may be more curved in one direction than the other, causing light to focus on multiple points in the eye. This can result in difficulties seeing fine details at any distance. Astigmatism can often be corrected with glasses, contact lenses, or refractive surgery.
