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.
