I just had to get glasses myself. The heartbreak of presbyopia.
I got progressives for general use and I've noticed that they work best when
you are looking directly at something--ie glancing at something doesn't give
good correction.

Your best distance correction might well be with contact lenses - no
distortion at all with them and peripheral vision is maximised (until
you start wearing shades!).

However you can get problems with dry eyes.
