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.
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.
My understanding is the current tech is not sharp enough for serious productivity, is too heavy for extended wear, and has a short life due to overdriving tiny OLEDs, so I'm not ready to purchase one yet. But some day those problems will be solved and I'm absolutely going to jump on that.
