I find a high level of correlation between eye strain with computer work and dehydration. When I drink lots of water, I experience less eye strain. I don't know if that will work for you, its just an idea. I also know that it doesn't just have to do with taking a break, because drinking once from a large container helps more than multiple drinks from small containers.
