Id say that if you are reading text all day on a monitor then panel types will make little difference - it will mostly come down to other factors such as glare off the monitor, brightness/contrast settings and how the text shows up (eg size of text, background colour, etc)
I too find my eyes are really tired at the end of the day (write a lot of sql at work) and havent found much that has helped besides taking some breaks from staring at the screen at regular intervals
