"Regularly-sized glasses" have to solve the power problem: in such a tiny amount of area, where's the energy source? For that you need wireless energy which seems to be electrified pie in the sky. Else some kind of insanely efficient solar cell innovation. Else bring back beanie hats with propellers in very high wind environments. Else, some kind of magic.
Otherwise, there are basically existing cracks are regular glasses products now.
See XReal for one good, fairly-polished example. Here's the latest version coming soon...
How do they solve the power problem? They must connect to a computing device that houses the battery. And how do they process the video one sees? The other device does that. How do you block out the bright light environments to not "cloud" the view? You would need some kind of other type of thing to wrap all around the exposed edges. Else bright light will get in between eyes and screens and dampen-to-overpower the virtual stuff you want to see.
So instead of a little battery with Vpro, you need a big battery and computer for XReal. You won't look as "odd" with XReal since they look more like glasses, but you will have to have this other tech to use them... and seek out (I wear my sunglasses at night) darker areas unless you can come up with some idea to keep the edge brightness from sneaking in underneath the lenses: like the old thick towel over one's head trick when trying to check a mobile screen at the beach... which then makes one look odd to complete strangers on that beach... even if the glasses look more typical.
I think the want would have great trouble in "regular glasses" too for the light intrusion and obviously the battery issue. So what we probably actually want is some kind of implant that won't need the glasses and is- in effect- invisible to others. That too still faces the powering problem but overcomes light intrusion. Which comes first: wireless energy or VR implants that work as well? Obviously, one of those must come first. So then the question is when?
And then does user of implant look like they may be dead when watching something in VR with their eyes open (that glazed over look)? Or does user look like they are asleep with eyes closed? If the latter, do they look odd to seem like they may be asleep but plunking away at the keyboard on the tray table while they type an email or WP document? As you can imagine, even the probably pie in the sky implant hypothetical has these "do I look stupid" scenarios.
The moral of the story??? Perhaps take a C.S.N classic message to heart...
