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 uniformly curved, the cornea or lens has more of an oval shape, causing light to focus on multiple points in the eye. This condition can affect both distance and near vision, and it is typically corrected with glasses, contact lenses, or refractive surgery. Symptoms may include eye strain, headaches, and difficulty seeing clearly at night.
