We have an interesting situation at a large company in the southeast.

We have been tasked to find some productivity-related reasons to use
larger monitors.  Most of our monitors are 17" HP versions that are at
least a few years old.

In curriculum development, we work mostly with authoring software such
as Adobe Framemaker, which requires more than one
document/window/catalog/etc. to be viewed simultaneously.  Often there
are SEVERAL of these things that need to be viewed at once, severely
overloading a 17" monitor's viewing area.  We spend most of each work
day glued to the monitors.

I gradually became aware of Computer Vision Syndrome (CVS) personally
after noticing this job was decreasing my distant acuity.  Normally I
have slight myopia (20/25) that was good enough for me to get an FAA
Class II medical certificate every year and not require corrective
lenses. After a year in this job, staring at the crowded 17" monitor,
I am approx 20/40 and for the first time in my 57 years, I may have to
wear glasses to fly legally.

I also experience other symptoms of CVS in varying degrees: neck
soreness, blurred vision, fatigue.  (Also, I have been told I get
cranky when I sit too long at the computer.)

While reducing the effects CVS is obviously important, the
bean-stackers are loathe to release any funding unless they can see
some productivity improvement or cost savings.  So, what I am after is
some way to show that new 22" monitors will be worth the $500 or so
each of them will cost.  The types of statements I need might sound
like these:
    - The reduction in CVS typically will reduce fatigue to the extent
that productivity will improve 10%.
    - Healthcare costs vary inversely with monitor size.
    - CVS with its associated discomfort and annoyance, reduces morale to
the point that increasing monitor size may have a direct effect on
morale-related productivity; possibly a 1:1 ROI.
    - Other large organizations have shown significant cost
savings/productivity improvements with larger monitors.

Thanks for any information.
