Green and amber phosphors sit near peak visual sensitivity, and phosphor decay produces brief light impulses instead of the sample and hold behavior used by modern LCD and OLED screens. These constraints may have unintentionally reduced visual fatigue during long sessions.
Modern displays removed many of those limits, which raises a question: is some eye strain today partly a UI and luminance management problem rather than just screen time?
Curious what others here have experienced:
Do certain color schemes or display types feel less fatiguing?
Are there studies you trust on display comfort?
Have any modern UIs recreated CRT-like comfort?

On the old ocilloscopes when you were getting some signals near the limit of device capability the traces could get pretty thin and hard to see sometimes.
With a less visible phosphor it might not have been possible to see anything at all at that point.
The green did seem to be a commodity for decades before the amber started becoming more common, never did prevail though.
I had two industrial monitors for non-PC's in the '80's that were vector-based and higher resolution than PC's had. Green was standard when launched, amber later became an option, and I ended up with each.
Liked them both :)
Top ocilloscope CRTs had already advanced way beyond the commodity green by then.
