Astigmatism is an eye condition that results in blurry or distorted vision. Today, we share a look at what causes astigmatism and how it can be treated.
What Causes Astigmatism?
Astigmatism is a type of refractive error like myopia (nearsightedness) and hyperopia (farsightedness), and is characterized by unequal curvatures in the shape of the cornea or lens. This results in blurred vision. The American Optometric Association (AOA) says that most people have astigmatism to some degree, and it can be present from birth or develop later in life. It can also decrease or increase over time.
Diagnosis and Treatment
Patients who exhibit symptoms of astigmatism – which, in addition to blurry vision, may also include poor night vision and headaches – must visit an eye doctor for proper diagnosis. During a vision test, your eye doctor will measure your eyeball and identify spots in the lens and/or cornea that generate astigmatism. At the end of the test, your eye doctor will have made a diagnosis. The next step is to prepare a treatment plan.
Like other types of refractive errors, one can wear eyeglasses to correct astigmatism. Specialty contact lenses like scleral lenses can also be worn for the same purpose. Patients who would rather not wear glasses or contacts and are willing to take the surgical route may also consider LASIK if their astigmatism isn’t as severe.
Exercises That Can Help Treat Astigmatism
There are certain exercises that you can do to treat symptoms of astigmatism, and, for some people, doing this may even improve vision. A common exercise that aims to relieve eye strain is the “20-20-20 Rule”: take a 20-second break for every 20 minutes of writing, reading or staring at a computer screen and stare at an object 20 feet away.
An eye massage can be done by placing two fingers on each eyelid. While applying gentle pressure, move your fingers slowly in a circular motion, alternating between clockwise and counterclockwise once in a while.
