Astigmatism is a refractive error where your eyes are unable to focus light evenly on the retina behind your eyes. This can be because of the irregular curvature of your cornea or any abnormalities of the lenses of your eyes. This can also be because of genes. Common symptoms are blurred or distorted vision.
