Inexpensive Ways To Reduce Computer Screen Blues?

I've been searching all over for a low cost solution to keep my eyes from becoming fried globes from staring at code for more than 8-13 hours straight. I've heard about screen protectors, but they do nothing. Knowing that the slashdot comunity has a large population of programmers and computer-tied people like me, I'd like to ask you all what you do to avoid monitor radiation and ways to protect your eyes."
