My astigmatism is not severe, but I wear progressives and I like them. They're like trifocals only better. The angle you tilt your head can determine the focus. It works once you've gotten used to them.

I too had a terrible time with them at first. Yes, your brain adjusts.

I did have one pair they messed up. I could get something in focus with one eye, then had to turn my head a tad to get it in focus with the other eye. They do have to get the lens centered perfectly with your pupils.

And yes, the magnification begins immediately under your straight ahead vision. I got me a regular, single vision pair for watching movies on my TV, since my head is tilted back slightly. As I say, the magnification starts immediately under your straight-ahead.

And again, yes, they take some serious getting used to. I like them very much.
