Is it the glasses that people wear, and it's internet enabled? They're not ready for commercial use yet from what I saw on the news.

I saw that. I dont think I'd be able to wear those. I get claustrophobic from weird things when I have optic neuritis. (weird, I know!) I tried wearing my sunglasses today (magnetic clip ons) and had to take them off because the sunglasses triggered my claustrophobia. Right now I'm really tempted to take off my prescription glasses because it feels like it's setting off the claustrophobia (that's never happened before)

I dont think they'll be practical for several reasons, but the biggest reason would be that people already have problems walking and talking/texting/breathing/thinking as it is now. There will be more people tripping down escalators and walking into traffic than there are now if people start using those.
