CRT Monitor: Eye Strain?

I spend about 8+ hours a day staring at a Gateway EV910 monitor
(Radeon 8500 video card).

When I go about my everyday life, everything I see seems to slower
then in the past (like looking at a CRT set at 60Hz). The reason I am
posting this here and not to misc.health is because I just want to
know if there is anyone else out there who has had this problem before
(or something like it).

Going out and getting a LCD seems to be a little to costly for me, so
for the time being I have turned down the brightness and contrast and
placed the refresh rate to 85Hz (highest). Any other suggestions?

Thank you!

Krhis

I prefer CRT's myself. But if I seriously thought that LCD's were better
for my eyes, what kind of value could I place on my vision?? Speaking
only for myself, I figure about $200.

They make polarized filters for CRTs. They're ugly things but they're
probably better for your eyes than looking at the bare screen. And don't
cost more than $20 or $30 USD

And you are how old? When I passed 40 something ;o) my eyesight became more
of a problem than I ever would have imagined...but it isn't the CRT...it's
presbyopia <sp?>. Not only do I have problems focusing close, I also feel
like you do that things don't seem to move at the same speed they used to. I
see things and have to take a second look to fully understand what I saw...

I too spend hours (8 to 10) on a CRT everyday, then a few more at my home on
a LCD laptop. Personally, I don't see any difference between the two
overall.

That's because the electromagnetic radiation from the CRT sets up an
interference wave pattern with the brain, causing a perception that time
has slowed down.

That's the Star Trek explanation.

No, *this* is the Star TrekŠ explanation:

"That's because electromagnetic radiation from the cathode ray tube in
the 3 centimeter range of the electromagnetic spectrum interferes with
gamma waves of the corpus callosum splenium portion of the brain,
causing a sympathetic excitation of the parahippocampal gyrus, on a sub
quantum level, which sets up an interference wave in the 400 to 700
nanometer range, changing the linear interpretation of the space/time
continuum to a logarithmic interpretation."

I would have gone into more detail, but I needed to take a breath. You
can learn more by running TWOS (Time Warp Operating SystemŽ ), available
from COSMIC, on your computer. A summary is available here:

Live long and prosper. \\ //

Reduce lighting glare in the path of viewing.

Keep visual distractions around: work near a window, put the clock
across the room andd turn off the screen clock, anything that helps you
look around and change your visual focus frequently.

Make sure the viewing angle is perpendicular to your face, and the
screen angle keeps your neck relaxed; that is probably a little below
your natural eyeline.
Arm angle to the keyboard needs to be similarly relaxed. If you have to
move your arms, hands, or neck (from a comfortable seated position) to
get into position to use the computer, something needs to move.
