Probably the most convenient thing I can think of is just putting my whole phone in my glasses. By my whole phone, let's say I'm talking about my whole dumb phone. So calls, texts, camera - this seems reasonable. And if I can ask for information and get quick answers that's a bonus. Disregard privacy concerns for the moment - that's obviously important and will be a bit sticking point. I would replace my phone with these if it was standalone. Or maybe this + watch in tandem would be neat.

If I didn't already need to wear glasses, that might change how I feel about it as well.
