Don't get this, what's the point in 1 device being corrected while the rest of the real world is blurry?
One use case example was a guy in a car with GPS navigation. So he can then see the GPS nav but how does he drive if he can't see properly!?

And speaking as one of the people whose vision defect can't be corrected by glasses, but only by uncomfortable contact lenses, there'd be immense value to me in a computer I can use without lenses - especially since reading on a screen is basically the only thing I need the damn things for while I'm at home. For someone whose work is mostly computer-based, you might be able to get away with taking your lenses out for the entire day and only wear them for the drive to work and back.
So they would also not be able to see their speedometer, or their fuel guage...
This is a technological solution looking for problems that are far more conveniently solved by conventional means.
However, until it is universally installed in cars and easily adjusted for your personal needs when moving from car to car, I doubt many people will be throwing away their bi/tri-focals in favor of lenses for distance only.
The video mentions both the GPS and speedometer as potential targets for this technology. Giving it some thought and being close to the age where I might benefit from this, it isn't such a bad idea after all.
(Although I'm short-sighted, so the arguments above don't apply to me anyway.)
Essentially, I'm getting close to doing the opposite of what most people do with reading glasses. For now, I do most minor reading tasks and my work with my glasses on, but for lengthy reading I take them off. Over time, I'm sure, I'll end up taking them off (or looking below my glasses) for almost every reading task, and eventually for work as well.
In the end, though, I don't think the technology will be likely to really solve the issue for me, except to correct a few displays for my corrected vision. I have to pin most of my hopes, at the moment, on improvements in surgery and eventually being able to afford the surgery.
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.
Sounds much simpler than trying to ensure a continuous supply of glasses for 500 energetic kids
Although I'm skeptical that third world countries will have access to high tech vision correcting tablets but not eyeglasses.
