    Do you really have screen flicker or are you working under fluorescent
    lighting?

    Someone recently mentioned to me that they have some type of covers for
    florescent lights to make their lighting more brain friendly. Does
    anyone out there know anything about this, or where I might get info
    about them?

    Monitor situations may be seen as being workplace ergonomic issues. As
    someone who works with three different computers & monitors on a typical
    day, I have to adjust to differing work environments, and lighting,
    while realizing that there are limitations as to what can be done to
    improve the monitor of itself. [My purchasing input is certainly
    limited.] A 0.28 dot pitch monitor will be 0.28 at the end of the day
    no matter what I do. While I can exercise some minimal controls to
    effect scan/refresh rates, the hardware ages (as do my eyes). The
    hardware might not have met the spec numbers in the first place, when it
    was shipped, other than having been within that magical +/- technical
    range. [Much the same is true for our eye glasses, relative to the +/-
    range of 'acceptable' optical quality.]

    I tried to find a technical article written by Jim Seymour, concerning
    monitors and viewing situations, a few years ago (in PCMagazine), but I
    had no success. The following brief treatment of eyes and distance
    situations was the best that I could do.

    Now as then, the medical community seems to be in search of a few good
    answers. With me, my doctor states the obvious, "you're getting old."

    I work in natural and incandescent light under most circumstances.
    Yes, I react to screen flicker. Most humans do and it contributes to
    eye fatique. Flourescent lighting just adds to the problem.

    I also try to remember to blink since the flicker of the screen keeps the
    old brain focused on the movement and it tends to forget to send blink
    signals. My personal strategy is to look away or close my eyes if it is
    not necessary to read the screen, such as when I am typing this posting.

    best of ergonomics to you
