Most straining thing with LCD monitors is the backlight and any temporal dithering (basically really fast flickering between 2 colours on a 6bit panel to fake 8bit colour, uses in most TN panels)
as long as the backlight isn't flickering and you have the brightness adjusted to a reasonable amount the backlight should be much of a problem.
either get a VA panel or IPS panel so they don't use temporal dithering (either the new BenQ LED VA monitors or the dell ultrasharps would get my recommendations)
and then you have to consider the the pixel pitch, if its too low text will be small and hard to read thus straining your eyes, if its too high then things may be blurry.
final thing to consider is glare, if you have a lot of glare on your screen your eye will be flicking back and forth between the reflection in the screen and the actual image, therefore you want to minimise the amount of glare.
get rid of glare
not too low pixel pitch
8 bit panel
