Synopsis: Researchers confirm that computer users taking a short break to look away from a device screen every 20 minutes improves symptoms of eye strain. Aston University researchers using special software to monitor participants’ gaze for two weeks, measuring symptoms before and after, proved for the first time that the 20-20-20 guidance rule is scientifically validated. Although we used sophisticated software, it’s easy for others to replicate the effect by setting a timer on their phone or downloading a reminder app. It’s a simple way of reminding yourself to take regular breaks for the good of your eyes.
