What is an Astigmatism and What Do I Need to Know About Them?

The word astigmatism is one you may have heard floating around the office of your optometrist. Maybe you have a friend or family member who has one. But do you actually know what it is? 

Astigmatisms are actually rather common and many of us actually have one in some form. But they make us see things fuzzy and unclear. 

In our eyes, light passes through our corneas which bend light in the front of our eyes. In conjunction with our eye lenses, light is focused onto the retina at the back of our eyes. Receptors in our retinas send those signals to our brain and thereby allows us to form an image. 

Normal eyes have corneas which are round and shaped like baseballs. But eyes with astigmatism have corneas that are oblong-shaped, or similar to a football. 

With astigmatism, the irregularly shaped corneas focus light on several areas in the back of our eyes, and not only onto our retinas. This, in turn, causes blurred vision at all distances. In most cases, astigmatisms are the result of genetics. But they can also be caused due to a variety of eye injuries. 

Astigmatisms which are bad enough can be fixed through corrective eyeglasses, contact lenses, or even through corrective vision procedures. 

If you believe you are suffering from astigmatism which is affecting your eyesight, contact your family eye care professional and discuss solutions for better vision.
