None of those things actually have anything to do with being less distracted. If you have a screen in your face throwing all the notifications and bullshit at you that your phone normally does, it is going to be far more distracting. And humans are hilariously bad at multitasking. Taking your hands out of the equation doesn't magically make you better at it. Jesus we think people using their phones while walking or driving is bad, these things are gonna be a disaster.

If people are so addicted to their phone or smart watch that it's giving them back/neck problems, the solution isn't glasses. The solution is to be less addicted to your god damn devices.

Outside of a few niche use case I don't think tech like this will be anything but a net negative.
