Oh, great. Now I'll have even MORE trouble staying awake through a prime 
time TV program.

These people who have so much trouble falling asleep at night should try 
doing a little physical labor once in a while. Believe me, after a day 
of that, a couple of blue lights aren't going to stop you from sleeping.

	Well when possible that is fine.  When I was younger I pursued
physical activity.  After I was in my 46th year that became impossible
and now at 79+ I am barely able to ambulate and carry home a few lbs
of food which I must then find the energy to cook.  I also have had
injuries or simple wearing  out of joints to contend with.

I don't have any trouble watching TV then 
falling asleep (or reading on a tablet or 
whatever).  My trouble is that I wake up after 
about 4 hours and the reason for that is 
something that I don't think changing light 
bulbs is going to fix.

There's something decent to watch on TV???   Wow!

There was an article about this recently - think it was probably in the
AARP magazine.    My wife bought a clock-radio some time ago, with the
large (~3 inch) 7-bar display (she can't see well without the glasses).
The display was a greenish-blue, rather than the more common orange or
red.  It lasted about two weeks before it was sent to Good-Will.  The
replacement is the same size, but red, with the intensity set to low.

Hah!  They can have it.  Now I have scientific justification for my
hatred of the blue-LED craze.  (Aside from my eyes' inability to
focus on those wavelengths.)

There exist programs to do this automatically at night (using the
system clock) Right now I cannot remember the name of any of them.

I had it running on my system for a while and then forgot about it.
Probably on there somewhere still.

	f.lux is referred to in the URL I posted but it is not compliled
for my OS so I simply went to the simplest (for me) correction.
	Back in my early Amiga OS days I regularly messed with color settings 
to off the overscan/interlace settings I used.

Not sure what you mean by "not compiled for my OS?

It is apparently a pre-compiled (ie not open source) program. It uses
randr to adjust the screen colour temperature at appropriate times of
the day, as defined by your location on earth.

I use redshift/redshift-gtk. Does make the screen much less annoying
to use.

I don't have much trouble with monitors.  It's all those gratuitous
brilliant blue LEDs (many of them flashing) which manufacturers insist
on putting on everything these days.  Once when I was doing sound for
a play, the board's pilot light was a blue LED that was so bright that
I had to cover it with three layers of masking tape so that I could
see anything else in the darkened hall (including the board itself).

I think the focus thing is true for everybody.  You're just clueful

Police cars on my city have blue light on their roof, very intense. I
happened to be driving behind one at night and had to increase the
distance: they blind me. Worse than headlights.

On the other hand, I don't have problems with computer displays. I just
set the monitor to "warm". No need to change it during the day with
software: I want whites to remain constant.

Our police cars have both red and blue lights.  Again, very intense.

And don't get me started on headlights.  When I become king, I will
ban HID lights from cars, and bring back the old standards for headlight
aiming and intensity.

It's a bit of consolation that I've figured out how to aim my side
mirrors so that if I'm being followed by someone with bright headlights,
they get a dose of their own medicine.  It discourages tailgating, too.

I suspect HID is on the way out--LED brings too 
much good stuff to the party.

On the other hand, don't really expect "the old 
standards" to make a comeback.  Florida used to 
inspect headlight aiming.  The gadget they used 
was mainly a way for some seller of gadgets to 
bilk the government--didn't matter where the 
headlights were pointed, the guy would jiggle 
the thing for a while and you'd pass.

We used to have vehicle inspection stations here in B.C. until they were
dismantled around 1982 as a "cost-saving measure".  Everyone took for
granted that you'd be flunked on your headlights - and near each testing
station was a service station that had the same equipment and which would
adjust your lights quickly and cheaply.

Back then we were taught that it was rude and dangerous to drive with
high beams in the presence of other traffic.  New cars' daytime running
lights - now mandated by the federal government - are often implemented
using high beams.  It's just one more of the kind of reversals that
politicians are famous for.

Your "eyes" are tremendously adapatable, and readjust their set point
for what "white" is. Under incandecents, "whites" are decideddly
reddish. Under Flourescents, green (You have surely taken pictures under
flourescents). But your brain renormalises its response so white stays
white.

Now, if you are in a green lit room, and your screen is "warm" it will
probably look very reddish.
