Mine is getting better, but varies a lot from day to day. This morning right after I woke up my right eye is bang-on perfect, 20/10, no noticeable astigmatism, and my left eye was terrible and I was seeing noticeable defects in the letters on the eye chart on the 20/20 line and 20/40 line (could read them but they looked like a Captcha image).
When I had my eyes checked they took hi-resolution pictures of the macula, retina, lenses, cornea, etc and all of that internal eye-hardware looks very good, no cataracts or anything like that. Sometimes astigmatism can be caused by cataracts, so I’d make sure you were checked by someone who can rule out any actual medical condition going on in your eye (cataracts, glaucoma, etc.) Then assuming there isn’t an obvious source of the astigmatism like cataracts…
There are lots of things you could try. The first thing is probably reducing eye-strain and improving habits or “eye hygiene”: increasing outdoor time as much as possible, taking regular breaks from screen time, pursuing Active Focus on distant objects, doing all the same things that help with myopia.
I would make sure you’re not wearing astigmatism correction (minus CYL) when it’s not required and that when you do wear it (because it does something useful for you) that you’re wearing the minimum amount of correction that gets the job done.
So, for example, if you’re wearing glasses with astigmatism correction when looking at the computer screen or you’re indoors where the astigmatism isn’t causing you problems, stop doing that. For myopia, it appears that excessive minus use sends stimulus to the eye to cause it to keep elongating, there may be similar forces at work with astigmatism where having minus CYL in front of the eye is causing it to grow increasingly myopic (lengthen) along the axis that’s getting corrected by the lenses. So in the same way that putting on distance glasses for close-up work can cause lens-induced myopia, you don’t want to be giving your eyes stimulus to lengthen or grow increasingly misshapen by putting minus CYL in front of them for tasks like seeing your desk where the lenses provide no conceivable benefit.
Driving at night is a task where the minus CYL correction might be useful, so I’d figure out how much CYL you need to get the job done and then wear that minimal correction only when it’s providing an actual benefit to you (such as driving at night where it might reduce glare from headlights and streetlights.)
You don’t want to get into the vicious circle of having minus correction (mostly useful for distance), wearing the minus correction all-day for near work and having your eyes adapt to that, and then requiring ever-increasing minus correction every year when you re-test. It’s sort of like drinking alcohol every morning to make hangover symptoms go away.
