One of the main parts of computer usage that causes eye strain is blur. CRTs only started solving this problem around the early 2000s and got discontinued shortly after. LCDs solve it for static images but not moving. E-ink will naturally have the same problem. Any moving image will appear blurry and your eye will try to focus on it and repeatedly fail, causing muscle fatigue.
Digression - This is of course less of an issue if you use the terminal in a style where you just move one page at a time, but you're just restricting yourself to a subset of possible use cases. I scroll in the terminal with the mouse wheel for skimming.
To solve motion blur, you either need strobing (along with a refresh rate above the flicker fusion threshold: ~80Hz), which E-ink will never have, or a high refresh rate, something like 240Hz. Still, if E-ink could even reach 50Hz it would be a massive improvement over LCD for use cases that don't require color.
E-ink does solve the pixel density problem and viewing angle problem (reducing eye strain and bad posture). Overall I'm still using high end CRTs for all use cases, and will switch to OLED once they get proper strobed offerings without all kind of bugs (and I'm still not sure if OLED fixes viewing angle shift. IPS-type LCD certainly didn't).
The self-luminescence problem that E-ink solves is also nice, but I'm not sure it matters much (it used to be my biggest pet peeve); you can just take an OLED which supports nice low luminescence levels at or below 120cd/m^2 (unlike most LCDs) and roughly match your room lights to it.
Low framerate and input lag will also cause eye strain and bad posture, respectively.
gives me nostalgia of the late 90s when some of my friends had those new experimental LCDs, the same aspect ratio, the same slow pixel response, interesting frame, and brands I've never heard of.
Buried the key sentence. That's pretty wild. Isn't any CRT now 20+ years old and consequently a small fraction of its design brightness? Or do you have old stock and you open a fresh box every 5 years?
I know there wasn't a lot of old stock of CRTs are the end of the CRT era because when I needed a warranty fix on a Sony 21" Trinitron FD in the final year of its 5-year warranty they said they could not repair or replace it and they send me a 24" model instead. When that one broke they could not fix or replace and paid me out for the warranty.
You only want your brightness to be something like 120cd/m^2 which is well below what most LCDs even let you adjust down to (even though that's what sRGB and all such common color spaces were designed for). A new CRT will go way above that until you adjust it down. Only got back into CRTs recently and collected a bunch from secret hookups.
I was surprised at how good a fake game like Genshin Impact looks compared to even the highest contrast VA LCDs. The difference is night and day. But then again the game spent all their budget on graphics and marketing.
Not the person you asked, but I still have and occasionally use an old 19" aperture grille CRT from right before the switch to flat panels. Brightness is still approaching eye-bleed if I crank it to max.
