Eye Strain Versus New Monitor

I am thinking of buying a new monitor because my old crt is just slowing up a lot on turning on.

I have been noticing some eye strain and I believe it might be due to my constant contact with crts.

I think LCDs are better for your eyes.

Are they worth the extra money? Is it really so much better?

Or is it just the space you free up?

Is it worth waiting to buy a LCD monitor or should I get a CRT?
