Another vote for cumputer-distance prescription. Also, I have two monitors so naturally switch my gaze between the two through the day as I work, which helps.

Another vote for cumputer-distance prescription. Also, I have two monitors so naturally switch my gaze between the two through the day as I work, which helps. One monitor is very large, and I set the resolution low so fonts and such are uncommonly large. Why strain? Remember to look up and into the distance every few minutes.
