In the last two to three years, I've hit a point where I need to take off my glasses (near-sighted, can't see things far away) to read my phone. I can still make out the text with them on, but it's physically uncomfortable and holding it at a distance helps.
I've been thinking about the existence of bifocals and how they aren't ideal as I come to terms with the inconvenience of removing my glasses and putting them back on repeatedly as I task switch. This sounds pretty great and I hope it's not smoke and mirrors (given enough time, science fiction tends to become reality, so I'm hopeful).
I'm at the same point you are, and a couple years ago I ended up getting bifocals, and let me tell you it's absolutely worth it! I ended up getting "multi-tasking bifocals" (what my glasses place called them), which are basically normal glasses with the lower area a second prescription for reading the phone. There are others that have 3 areas (reading at the bottom, distance a small spot in the middle, and then a middle ground elsewhere).
I didn't really want to get bifocals because it's what old people wear ;-). But it's so much better with them.
The glasses place (CostCo Optical) guy was kind of a jerk about it, all but saying "you're going to wreck your car if you use these for anything but at your desk", but I just "yeah, yeah"ed him, I like my prescription dialed back a bit from max power for day-to-day use.
If you can afford it, maybe give them a try? Zenni and other onlines might make them affordable enough to just try?
