Many people have vision problems where the eye can't easily focus on a variety of distances. So if you have glasses, they're set up to make focusing on one distance easy, but things closer or farther (if that distance is not "infinity") is more difficult. I have progressive bifocals to get some amount of varying correction with distance, but this is thrown off for computers since they take up more of your field of vision than a book. (I also find looking at my phone through the bottom of my glasses to be pretty awkward, even though I've had bifocals since elementary school.)
One solution is an extra pair of glasses for computer work, but this is annoying because you can't get up and go to the bathroom without changing glasses. If the computer monitor were set to add the extra correction between my normal prescription and the intermediate distance prescription, my life would be much better. (Same for my phone.)
Right now, I can pretty much focus without using anything more than my distance prescription, but as I get older, this will become more and more difficult. So I'm pretty excited about this; less eyestrain is always good.
Also, the ability to tweak the correction in software is great. Where I have my monitor isn't quite what the optometrist was expecting when I had my computer glasses made, so I have to change positions to use them. With control in software, I could just adjust some config file somewhere when I rearrange my desk.
