The effects of breaks on digital eye strain, dry eye, and binocular vision: Testing the 20-20-20 rule was published in Contact Lens and Anterior Eye journal. It's a simple way of reminding yourself to take regular breaks for the good of your eyes." "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. The findings confirm that people should try and take screen breaks. "We are planning to conduct longer-term studies to see whether we can teach eyelid muscle memory impulses to blink more often during digital viewing to help mitigate this chronic issue without long-term use of reminders." Researchers noted that after the study, the participants' eye symptoms returned to what they had been before the intervention. We saw a consequent improvement in the symptoms of the group as a whole." "The one previous study merely asked people to carry out the suggestions, but here the access control on the software meant we could be sure that participants really had looked away every 20 minutes. Professor James Wolffsohn, Professor of Optometry at Aston University, who led the research in collaboration with the University of Valencia, Spain, said: Results showed a marked decrease in symptoms, including dryness, sensitivity, and discomfort. Participants' digital eye strain symptoms were measured before and after two weeks of using the reminders and one week after completing the study. The message couldn't be removed until the task was performed correctly, as measured by the app. Special software downloaded onto the participants' laptops used the built-in laptop camera to check if a user was sitting at the screen and to monitor their gaze direction every few seconds.Īfter 20 minutes of continuous screen viewing, the program flashed a message, asking users to rest for 20 seconds while looking at any distant target around 20 feet away, such as out of the window or across a room. Researchers at Aston University's College of Health and Life Sciences set up their study with the help of 29 participants who suffer from symptoms of eye strain. This is the first time that the 20-20-20 guidance rule has been properly validated. That can lead to dry, irritated, and tired eyes, but twenty seconds of focusing elsewhere is long enough for the eyes to relax to reduce the strain. When staring at screens, this number generally decreases to half that rate or less. Humans normally blink around 15 times each minute. It's estimated that at least half of people using computers in their regular work have some form of digital eye strain, resulting in eye surface problems, including irritation and dryness, or vision issues, such as headaches or blurred vision.
