What is astigmatism?

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea is irregularly shaped or sometimes because of the curvature of the lens inside the eye.

How can you tell if you have astigmatism?

Astigmatism is determined during a complete, routine eye exam. It is easily determined by checking your eyesight or measuring the curvature of the front of your cornea. If you have astigmatism, your eye care provider will let you know during a routine eye exam.

Can astigmatism be cured?

Astigmatism cannot technically be cured, as it is a permanent condition. However, it can be corrected with glasses, contact lens, LASIK, PRK, Refractive Lens Exchange or intraocular lens replacement with cataract surgery.

What is the main cause of astigmatism?

Astigmatism occurs when your cornea or lens is curved more steeply in one direction than in another. It may be present from birth or develop after an eye injury, disease or surgery. Astigmatism cannot be made worse from squinting, reading in poor light or looking at a screen too closely (as common myths might suggest).
