Having two monitors at different distances/angles is what has worked for me after almost a year of pomodoro'ing with no better results & slightly blurry eyes at the end of a work day. Also look at monitors by moving your eyes & not your entire head, just like pilots. Finally drink lots of water every hour. The pee breaks will help with sedentary lifestyle problems, improve circulation, give your eyelids a break & act as a breather between work bouts.
