Most modern LCD monitors do not allow for refresh rates higher than 60Hz because increasing it
does NOT reduce flicker (if there's any) that is caused by incandescent backlight, flicker of which you can't control using software. In other words there's no reason to increase it, neither technical (60fps is enough) nor medical.
On the other hand, if you're still using CRT's increasing refresh rate makes perfect sense.
you are absolutely correct.
with LCDs the only thing that can really effect anything at all is the response rate... and when dealing with mainly text, anything faster than 16ms is more than enough for the human eye.
Everyone who has said something about the eye strain and eye fatigue I think is spot on. The only reason to change monitors would be if these were slow... but they arent... 5ms and 6ms is more than fast enough.

You're supposed to look away every 15 minutes. Surprised no one knew that. The human eye wasn't "designed" to look at bright sources of light for sustained periods, duh. Yes take breaks. But every 15 minutes look away for at least like 30 seconds. Keep lots of ambient lighting so you're not going from dark to bright. Also consider upgrading contrast ratio. More dense packed pixels means less eyeball torture.

I know a farmer who has worked outdoors his entire life looking at distance objects. His vision is now something like 20/15 but he can't read a newspaper. He can also tell you the weather 3 days in advance and shoot a hole through the center of a quarter thrown into the air, but that's another story.

CRT monitors are known to produce health effects, including seizures (via photosensitive epilepsy), with lower refresh rates. I believe my doctor told me 80 mHz or higher is best.
LCD monitors do not have the same effect.
Have other lights on when you are doing you work.
And also, it might not be the monitor... but just working that much!

I slept for a solid 10 hrs and replaced all the lighting in my office with incandescent bulbs.... so far, MUCH BETTER!

Also the real reason might be unrelated to both monitor and eyes. Buckit could have spine bone dislocation in the neck preventing proper blood circulation in his head, affecting both eyes and brain. I went through an eye surgery several years ago because of similar issue.

Could be not sleeping, eating, exercising right, etc.. When you get "bags" under your eyes and the skin turns dark thats blood leaking out of the capillaries just under the skin and pooling, like a bruise.

Would hope my multiple CAT scans and MRI's would have shown something (They were all general to find anything at all abnormal... long story... turned out to be dehydration.. again, long story). so no its nothing like that.

I get atleast 7hrs of sleep per night, eat a healthy diet and run 20-30 miles per week... not to mention roller blading or biking inbetween.
