All LCD's are easier on the eyes even compared to the latest CRT's.
A 15" LCD will have a native resolution of 1024x768. If you find text hard to read and reduce the resolution to 800x600, the display won't be as sharp.
LCD's aren't meant for gaming because of low refresh rates. Games will be slightly blurry compared to CRT's. Running a game at 640x480 make it look even worse.
What do you mean by 'Easier on the eyes'?
If you mean sharp text and graphics at a resolution of your choice which is easily legible, then go for CRT.
If you mean less radiation given out by the monitor which harms your eyes irrespective of how sharp the display is, go for LCD.
