Easy-on-the-Eyes Switch

[Kevin Hunter]

Hello everyone,
 
I'm currently working with two 19 inch monitors, which definitely has it's plusses, but a suspected downside is that it's irritating my eyes. Most of the time I spend actually staring at the screen (with no breaks) is in Frame. Does anyone know if there's anything like an 'easy on the eyes' visible color scheme switch? 
 
Some of our software is for the ye olde green screen (black background, green text), which may be rudimentary, but definitely isn't visually overstimulating...
 
thanks,
 
kevin
