Just FYI, and possibly a little late (eek!), there are a couple of
apps which do this
I used to use another one, the name of which escapes me, but can't
find it now. Its icon was three coloured discs. A quick search of macupdate.com
throws up

(I've not tried either)
AFAIR the one I used to use modified system gamma, so worked without
any extra windows, etc.

Yeah, it's for astronomy. If you're working at a telescope, you want
your eyes fully dark adapted. Having a computer there is really useful
(especially if you're using the QC based realtime telescope imaging +
processing app I'm writing :)), but a regular osx desktop will ruin
your night vision.
So what I'm doing is adding an overlay over the whole desktop, which
does a few things to help. First, it makes the screen red. Red light
doesn't affect your eyes as much as the other colours. Then, it makes
everything darker, which helps more. I'm trying to add a backlight
control too so the backlight can be set to almost off.
I'll also use QC to add a "screensaver" effect so it'll run a black
bar down the screen or something every x minutes to prevent screen
damage (this way the real screensaver can be turned off.. you wouldn't
want a bright screensaver coming on when you're not looking :)

Can I ask why you're building this?

Yeah, I found that, but thanks :)
Actually I have the whole thing working now. I've not added QC in,
but
my app is now adding a fullscreen overlay on all monitors, with
mouse
event passthrough (so far it just tints the screen). Adding QC stuff
is just a case of adding a QCView/OpenGL view to the windows and
rendering.
I'll post my code up somewhere when it's done, I guess people might
find this useful.

Just got to figure out event handling now and I'm good to go.
This might do the trick:
[window setIgnoresMouseEvents:YES];
