So when I finally graduated to progressives I already had the head movement training down, and the transition was immediate. Now I wouldn't be without them.

Update:
After my last refraction I got another pair of progressive lenses, but unfortunately the height of the stronger part of the lens was lower than the old ones, and so when at the computer I had to tip my head back farther resulting in neck pain. Since my prescription had only changed minimally, I ended up going back to my old glasses.
Then I recently had cataract surgery and opted for an expensive "premium" lens that is both accommodating and toric.
The toric part means that it corrects my astigmatism and that part works very well, giving me an improvement of three or four lines corrected to uncorrected.
The accommodating part means that the lens has a little hinge that changes the focal length depending on the tension of my ciliary muscle (the muscle in the eye that focuses the lens in young people). That part is a bit more problematic, and I now need reading glasses for anything less than about 12 pt. I'm told that this is because my ciliary muscle has atrophied from disuse, and that exercising it will improve the performance over several months. We shall see.
