One factor that helps me is to set my IDE syntax coloring schemes to minimize the amount of blue one the screen. Mostly yellow, green and brown text with hilights of grey or cyan on a black background. Staring at glowing text is much better than staring between the glow in a futile effort to mimic paper. Blue light makes focusing more difficult.
