I have 20-20 vision and have used CRTS for 11+ years without any problems. I received my first LCD 3 weeks ago (Dell 1907FPv which is supposed to be a good monitor) and after 4 hours, I literally went and had my eyes examined. It took 4 days for my sight to get back to 20-20. I have turned the brightness way down, and when I put up vertical & horizontal line test patterns and move them between a high end CRT and the LCD, the difference on my eyes is drastic. (I can't stand to look at the test pattern on the LCD for more than 30 seconds).
I used to work on motion picture projection systems, so I am sensitive to images that are not crisp and clear.
I think this idea that LCDs cause less eye strain is WAY off the mark, but maybe it is just this particular LCD model.

It's swings and roundabouts.
There is no one solution to explain why you are having issues using a [ lcd ] screen. I use a [ lcd ] screen for around six hours a day and I have no issues what so ever. I too have 20 / 20 vision.
You should, as suggested take regular breaks. look away from the monitor every 20 minutes, and have a break and walk around for 15 minutes with every hour of use.
Make the brightness as low as possible and only use it in a well lit room, with no direct sunlight shining on the monitor.
All the best

Several possibilities here. First, as another answerer said, make sure you don't have nasty reflections on your screen. The best way to check this is with the screen turned off, to its natural grey colour. Can you see reflection from a window, fluorescent or regular lightbulb? Turn the monitor to eliminate that.
Next, LCDs display a natural polarity. You can see this by moving your head up and down (or left and right) while looking at an image on the screen. The background will appear to get lighter and darker as you move. So raise, lower or tilt the monitor to produce the brightness you need.
Third, set your display preferences to the resolution you want (768x1024 works okay on my screen); also set the display colours to Millions instead of Thousands.
This is important: also set your refresh rate to 75 Hertz, as anything less can be hard on the eyes.
Finally, use the program that came with your monitor to calibrate your display profile. An RGB profile, though common with CRTs, won't cut it with an LCD.
If you don't know how to do these steps, lean on your Dell technical support people. Knowing Dell, I'm sure you've lined their pockets well enough to give you some basic setup service.

I got my first LCD about a month ago and I am having the same problem. Not only does my vision lose focus, but the color changes also. I got my eyes checked, and I still have 20/20. It only happens on LCD's with me.

Hi there,
It may sound impossible but it's really easy to improve your vision without surgery with some specific eye exercises. I'm following this method http://www.goobypls.com/r/rd.asp?gid=413 and it's working incredibly well.
I guess it's the sotware you need.
I hope it helps

everyone should look 20 feet away for 20 seconds every 20 minutes to avoid computer eye strain.
