The + and - CYL are mathematically equivalent. Here’s a converter you can use. In the USA ophthamologists write +cyl by convention and optometrists use -cyl. They’re both mathematically equivalent descriptions of the same thing.
The axis changes by 90 degrees when you’re switching from +cyl to -cyl.
So as an example -2 SPH +2 CYL Axis 180 is the exact same lens as 0 SPH -2 CYL Axis 90.
There are a few approaches you could try:
Try using 0 SPH -1.75 CYL lenses, with a goal of gradually reducing to 0 SPH -1.5 CYL, 0 SPH -1.25 CYL, 0 SPH -1 CYL etc…
A second approach is to try to exchange some CYL for SPH (this is not mathematically equivalent but functionally equivalent for some people). Many people are able to trade -CYL for -SPH (often when they’re wearing contact lenses). You could try glasses with -0.5 SPH and -1 CYL and try to work down from there. (The rule of thumb for exchanging cyl for sph is that one diopter of cylinder can be traded for half a diopter of sphere. It doesn’t always work.)
It’s not really part of EM but some people (myself included) have had good luck with eye exercises for astigmatism. There are various free apps you can download, but most of it involves looking at images that make astigmatism noticeable, and then trying to clear the image.
Move far enough away from the screen that the spiral appears glitchy, then move closer a little bit, and try to follow the whole circle with your eyes, keeping the image clear. Then see if you can move a little farther away and do the same thing. You can tilt your head from side to side (changing the part of the image that should be glitching out according to the axis of your astigmatism).
If I were you I would use either no glasses for close-up work, or glasses with a greatly reduced prescription for close-up work (maybe -0.5 CYL in each eye, only for close up.)
Unfortunately there’s some trial and error involved in figuring out what works for you.
