What to Know About Astigmatisms
Here are a few facts of note about astigmatisms:

Your cornea is supposed to be shaped more like a softball than a football. When it starts to look like a pigskin, it causes the light rays to change on the retina. This results in blurry vision.
An astigmatism can also occur to the eye’s lens if it has an irregular shape. Called lenticular astigmatism, the condition has the same results as standard astigmatism. It should be noted that an affected lens is far less common than an affected cornea.
You’re more likely to be diagnosed with astigmatism if you have far- or nearsightedness. (Also, sitting too close to the TV has nothing to do with astigmatism!)
