Astigmatism is a common vision condition that happens when a person’s cornea is not symmetrical. These type of people need contact lens for astigmatism to correct their vision. Light entering the eye is not focused on a single point on the retina, so objects both near and far become blurred or distorted. An astigmatism can also occur in the lens of your eye, which sits just behind your cornea. If you’re diagnosed with a lenticular astigmatism, it means you have a misshapen lens.
