they are paying the price for their obsession with super high resolution. I think it's a mistake, from my perception Quest 3 at 25ppd is nearly good enough, and its panels are nearly half the resolution. They should have traded 20% resolution for 10 deg FOV either side. In fact, with appropriate optics the effective resolutions sacrifice could be even less than that.
Well, it's no Retina screen. I'd say it's bit like reading text on a 1080p CRT at 96 dpi.
It's perfectly doable, but there's still a hint of fuzziness and we're still a couple generations away from crisp LCD text.
I care about my eyes, so I use a 4k screen at 2x scaling for coding, and will not use the Quest 3 for work, unless that involves playing games and watching videos.
