What is astigmatism?

Astigmatism is myopia in a specific axis of the eye, as opposed to myopia for the whole of the eye.

Is astigmatism genetic?

In 99% of cases, no - astigmatism is induced. Actual genetic astigmatism is incredibly rare.

Can you reverse astigmatism?

Yes. Many participants have been able to reduce their astigmatism correction.

How do I know if I have astigmatism?

If you have a prescription from an optometrist, look for Cylinder or CYL. The Cylinder value is your astigmatism. The axis value is the plane in which the astigmatism is present.

Less than 1 diopter of CYL

In the majority of cases, you can ditch astigmatism correction entirely if it's under one diopter.

More than 1 diopter of CYL
