They take a month or 2 to get used to, give it time. Your brain sort of morphs itself to make it seem normal after a while. It’s very strange but true.

I personally went for only 2 zones, one which was mainly the strength to use a computer rather than read a book up close (though I can do that in a pinch), and the other for distance. This feels very natural to me now, I can just see what I need to see but it doesn’t feel weird.
