What is astigmatism?

Astigmatism is a fairly common and usually minor condition that causes blurred or distorted vision. Those who wear glasses have variants of the condition which is caused by an irregular curve on the cornea. This means it fails to process light to a single focus and therefore causes blurred vision and the need for spectacles.

Can you have astigmatism without knowing?

It is possible to have it without knowing. Children most commonly suffer with it as they are not aware of their vision being anything other than normal. It is also possible for some adults to have mild astigmatism without any symptoms, having a comprehensive eye exam will enable further information.

How do you detect astigmatism?

Our professional eyecare experts at Goldsmith Webb Opticians can detect it by using an astigmatism chart to help determine the curvature of your cornea or lens. An abnormal curvature will sharply focus parts of the image on your retina, while blurring others.

How do you correct astigmatism?

There are a number of options available to correct it. Glasses are the simplest and safest way, talk to one of our experts to find out which would be best for you. Contact Lenses work by becoming the first refractive surface for light rays entering the eye, causing a more precise refraction or focus. They provide clearer vision, a wider field of vision and better comfort. Refractive Surgery changes the shape of the cornea permanently. This enables light rays to focus precisely on the retina therefore improving vision.

It is important to note that everyone’s eyes are different. Therefore the way in which astigmatism is treated is different for everyone.
