We've consistently found that
1) Green monitors are harder on your eyes under fluorescent
light.
2) Amber monitors seem to be the easiest to work with.
3) CHEAP green screen terminals whose color temperature is
right around that of the fluorescent lights leave me and one
of my coworkers literally sick after a work day. (Headache,
nausea, etc.) In contrast, the same make and model of
terminal with an amber monitor is o.k.
4) GOOD green monitors are better than equivelent quality
blue monitors. I am specifically thinking of my experiences
with DEC Rainbow micros and 220 terminals.
5) Fluorescent lights in general are a pain. Here is one
story: Wyse 75 terminals have this nausea colored green
monitor. I've used twin terminals at two sites, one under
institutional fluorescent, one under house incandescent
lights with some natural light. Under fluorescent lights, my
eyes gave out. Under natural light, I find the terminal
fine.
6) Color terminals, even when set to green, amber, whatever,
tend to be harder on the eyes. (Lower resolution, etc.)
7) Flickering reverse video drives me nuts. Wyse 75 magic
cookie specials are the worst.
I have also noticed that people tend to turn up terminals way
too bright, and that they tend to use them in rooms which are
at the brightness level for reading, which is way too bright
for CRT work.
Interestingly enough, people who are used to cheapo micros
get used to the green monitors better than those of us who
have finer tastes. I know of some Apple ][ people who PREFER
the terminal which makes the people who work with me
literally throw up.
