I noticed that a while back a question was asked about personal preferences in terms of color schemes for vim (http://stackoverflow.com/questions/524585/what-is-your-favorite-colorscheme-for-programming-in-vim). Though the author did note that colors can have an effect on your eyes equal in effect to ergnometric keyboard on hands, the question seemed to end up essentially being "vote up you're favorite colorscheme."
I'm wondering is there any research out there concerning the long term of effects particular color schemes. (I'm interested in research on effects on the eyes, not studies on preferences.) Although I find darker schemes more aesthetically appealing, I've heard that whites are easier on the eyes. If I'm going to be staring at screen 8 hours a day for the next 30 years of my life, I'd love to be made aware of any research that will point in me in the direction of something that can save my eyes.
