Astigmatism is an eye condition which causes blurry or distorted vision. Continue reading to learn more about what causes astigmatism, and how it is treated.

What Causes Astigmatism?

Astigmatism is a refractive error in the eye (similar to myopia--nearsightedness, and hyperopia--farsightedness.) Astigmatism is characterized by unequal curvatures in the lens or cornea. This irregular eye shape leads to blurry vision. According to the American Optometric Association (AOA), most people have some amount of astigmatism, though in many cases it is small enough so as not to be noticeable. Astigmatism can be present from birth or develop later on, and the degree of astigmatism in your eyes can both increase or decrease over time.

Diagnosis and Treatment of Astigmatism

In order to receive a proper diagnosis of astigmatism, you must see an eye doctor for a proper eye exam. During this test, the doctor will measure your eyeball and identify places on the lens or cornea that are causing your astigmatism. Once the test is complete, you will receive your diagnosis, and the doctor will help you prepare a treatment plan.

As with other refractive errors, you can wear eyeglasses or contact lenses to correct astigmatism. If you do not wish to wear glasses or contact lenses, and your astigmatism isn’t too severe, you can consider the surgical route and look into LASIK.

At-Home Exercises Which Can Help Treat Astigmatism

In addition to wearing your glasses or contacts, there are some exercises you can do anywhere that can help treat the symptoms of astigmatism, and may even improve your vision. One exercise commonly used to relieve eye strain is the “20-20-20 Rule”. This entails taking a break for 20 seconds after every 20 minutes spent reading, writing, or looking at a screen to stare at an object 20 feet away.

You can also massage your eye. This is done by placing two fingers on each eyelid, applying gentle pressure, and moving your fingers, slowly, in a circular motion. Alternate between clockwise and counterclockwise.
