Interesting, I have minor astigmatism and have the opposite problem, a light background blurs the text for me while a dark background and white text is nice and crisp for me.
Astigmatism definitely has different orientations (a 360 degree angle figure) but it affects the direction the blurriness goes. Not the amount of it.
I also have it but not super bad. For me it’s still much better to have a little blurriness at night than burning my eyes out on a white background (thanks google for popularising the “white on light grey on white” design mantra)
They can and do. That’s what the optometrist is checking when they flip the little lenses around and rotate them and it’s obvious it wasn’t to change the focus. It doesn’t get more/less clear unless you have astigmatism when they’re flipping those ones (at least in the same way).

Maybe astigmatism can have different orientations, it’s a wrongly shaped lense, after all. And there are many false shapes for that.
