One tip I learned ages ago is to look at and focus on differently distant objects regularly. So every 5-10 minutes (now it's a second nature habit), I scan the room and randomly focus on objects nearby and objects at a distance. Focus on 3-5 objects per scan, each at a different distance. If you have a window nearby, even better: look outside and admire far away things. Of course, if you get out of your seat and take a walk while looking around, you get the double combo of moving and reducing eye fatigue. Also adjust the brightness. After a lot of experimentation, I discovered my comfort zone of having relatively dim screens. And get a flat screen!
