20-20, been in front of CRT monitors for well over 10 years now. But I keep a good distance. Right now my 19" CRT is about.. 3 1/2 to 4 ft away. Bad vision does not run in my family.
I can look at this thing all day and my eyes don't hurt much, depending on how much reading I do though.
i can sit in front of LCD's much longer than CRT's. both monitors i use to have used a 60hz refresh rate, same as my LCD. if i get slight strain i just turn down the contrast via some presets, really cool feature.
they were crappy\old, they couldnt go any higher. i could look at them for a long time compared to some people, 5+ hours in a 5 hours 10min time period
