LCD Advice, please help me. My Eyes are bad!

Hi people, I hope someone here can help.

I have always been funny with monitors.
I always have been had good CRT's such as sony's 17" a sony 21" and now a NEC FB21FB Diamond Tron tubed monitor. tho they r gettin old.
I love the crt's for the high hz rate they support. usually they are calm on my eyes!

pretty much every LCD monitor I have used have hurt my eyes since they only operate at a max of 75hz
my crts can usually do 150hz!
eye feels like it gonna pop! sometimes have to look away and close for eyes HARD, if using for an hour or so..

I have 3 LCD's and they all pretty much hurt my eyes. after few hours of use, same as my wife!
they are pretty cheapo lcds, such as a 19" samsung 19N 15" samsung15N and another 15 Viewmaster!

if I buy a DVI digital LCD monitor maybe a 21/22inch screen of the higher end scale do they have higher hz? or anything good for my eyes!

lastly what is the ms rating.. thats the refresh or something? how would a 12ms vs a 8 or even 4ms screen compare, better for eye strain for only better for viewing pleasure?

I know it a long post sorry for that! but I really wanna get thing stright before I spend big $$$ on a new screen that gonna kill my eyes!

thanks in advance

Refresh rate on an LCD monitor has no effect on eye strain. LCD monitors work completely different than CRT monitors; so refresh rate does not make sense to have any effect on causing eye strain, headaches, or nausia (like it can on CRTs).
However, there are some factors that may be an issue:
The bulbs used to light LCD monitors supposedly flicker at a very fast rate (over a 1000Hz perhaps?, not sure); some people have noted problems with older LCD monitors perhaps due to the use of the bulbs.
Turning your LCD monitor up to full brightness might hurt your eyes. It is recommended that you turn down the brightness of LCD monitors (which may be controlled by the contrast slider); this is the main reason why the brightness spec is pretty worthless for LCD monitor use.
The slow response time of LCD monitors might cause you issues as well. All LCD monitors (except maybe for the special 120Hz or BFI models) show a smearing effect during motion; that is, you will be unable to focus on exact details when an object is moving, unlike on CRTs.

Regarding refresh rates on LCD monitors, one way that it may affect you is something like when you are trying to move you mouse around the screen and it does not update the motion fast enough for you. For example, maybe you were to feel that at 60Hz, updating the position of your mouse 60 times per second was not fast enough for you. Or perhaps you were to notice that 60FPS was not fast enough for an action game.
