You can already do this, and I did it last week on my flight with my Xreal Air.

Yeah, that's the brand I've been watching most closely. How would you rate the sharpness of the display for text editing / coding? Like if you opened some large code files on your glasses and desktop monitor, and adjusted both their font sizes to have the same legibility + feel, do you fit more text on the glasses or your desktop monitor and by how much?

This is the one aspect that is hard to find info about online. Everyone talks about the weight and what size the virtual display is, but if I am going to seriously use it for productivity then I need at least 3 files open side by side, fully legible, with 100-character-wide lines at the bare minimum to be considered.

Either way, I'm not going to purchase until they solve the longevity problem, but I am curious if the sharpness is at the point where I can stop worrying about it.

		It's literally a 70" HD display around 4m from your face. All HD displays fit exactly the same amount of text in their 1920x1080 pixels, the only thing that changes is the field of vision the display takes up. I use them to do work, the issue I have is, having owned three pairs (for reasons), the lenses can be hit-or-miss. The pair I own now is more on the miss side, and some part of the lens is blurry. You don't notice it when watching films, but it's noticeable for text. The other two pairs were OK, this one I got less lucky with. This one also seems to tire out my eyes if I wear the glasses for more than an hour, and I don't know why (it might be the blurriness). It's not the focal distance, they did a good job there, it's about 5m as far as I can tell. Anyway, overall I like the glasses. They're worth the 200 € I paid used, but I probably wouldn't pay 400 € for them, I only use them on flights. They'd be great if I watched lots of movies or played games on a Steam Deck, though.
