speaking as one who has had bifocals for ten years -- you don't adjust where you hold the book, you'll find yourself moving your head instead. I have graduated bifocals (which I love, and took zero time to adjust to), and everything is in focus, if I adjust the angle of my head. It's something I tend to do subconsciously.
Only recently I got a second pair of "monitor" glasses, that are in focus for something 50cm from my eyes. I had found I was taking my glasses off when working at my computer, to read the screen, because my eyes are now to the stage that I was getting a sore neck from tipping my head back (again, subconsciously) to look through the bottom of the bifocals. But that's a) only recently (after a decade of bifocals) and b) because I spend LOTS of uninterrupted time looking at an object I can't move, or move relative to.
but I'd recommend the bifocals for daily use, there's more to look at up close than monitor screens.
