Most obvious one for me is I try to do as much work as possible (where work = typing) in dark mode, i.e., amber or colored type on a black background. I wish there was an acceptable way to view web pages in dark mode, but the vast majority of web sites look like garbage and are functionally unusable if you change their color scheme. I rarely read long documents on a monitor. If it's something that will take longer than 2 or 3 minutes to read, I will print it and read it away from the computer. Other than that, I just try to make sure I take breaks, and one thing I've trained myself to do is to recognize when I'm pondering something and to turn my head/body away from the monitor and look at something 10 or 20 feet away while I'm pondering.
