How do optometrists find astigmatism?

Astigmatism is diagnosed by an eye exam. A complete eye exam involves a series of tests to check your eye health and a refraction, which determines how your eyes bend light. Your eye doctor may use various instruments, aim bright lights directly at your eyes and ask you to look through several lenses.

What will happen if astigmatism is not correct?

Astigmatism is caused by the shape of the eye’s cornea or lens, and glasses can’t change those. However, wearing glasses with an incorrect astigmatism prescription can cause other problems, including blurry vision, eye strain and headaches.

Can astigmatism be misdiagnosed?

Astigmatism is genetic, and children are usually diagnosed with it after they start school and have a hard time reading or concentrating. In fact, it’s fairly common for children to be misdiagnosed with learning or behavioral disorders when they just need glasses.

How to test if you need astigmatism correction?

Measure Your Astigmatism. If you just have average myopia, it is simple to determine your astigmatism correction needs: If you have less than one diopter of astigmatism correction, you might not need it altogether. In cases where the myopia is also quite low, I often recommend to eliminate the astigmatism correction.

Do you have to change cylinder correction in astigmatic blur?

Careful with changing cylinder correction, since not enough means you’ll end up with astigmatic blur Astigmatic blur = directional blur.
