I turn the brightness on my monitors way down and use redshift on computers and lux on my phone. (The color temperature thing is more about improving sleep than ocular health, though.) I also use slightly less powerful (by ~.25) contact lenses than I otherwise would. When my eyes get tired in the evening, I switch to glasses. Oh, and I almost forgot: I also recently started using a chrome extension called "Hacker Vision" that basically makes all web pages reverse-video, so there's even less light hitting my eyes. It takes a little getting used-to, but I quite like it now. I hacked it up locally to preserve color and just invert value, instead of doing a straight rgb invert.
