Astigmatism is a really annoying eye condition that means you have blur in a specific direction, or axis. Astigmatism is compensated with cylinder lenses.

You have astigmatism, maybe a lot of it, maybe only a little. Of course you want to deal with this as well. You need to start with understanding what causes it. Astigmatism is caused by an irregularly shaped cornea or lens. The first is called corneal astigmatism, which is the more common form, and the second is called lenticular astigmatism. Here is a good introduction to astigmatism https://endmyopia.org/the-definitive-guide-astigmatism/.

How do you reduce it? Well, in the same way as you reduce your myopia, in small steps. If you have only a small amount of astigmatism, say .25D, you could drop your astigmatism correction straight away. If you have a lot, it will be more complicated to tackle.

Astigmatism often reduces spontaneously as myopia is corrected.
