What causes more eye strain/dmg: LCD or CRT?

[kremlin456]

What type of monitor causes more harm to your eyes? Which one exerts more radiation? While I imagine both have detrimental effects to one's eyes, which of the two is more dramatic?

I asked my optometrist this same question a few days ago. he said flat screens are better than curved. Also, CRTs spit out a ton of electrons which some think may have detrimental affect on the human body. flat screens don't do this.
