Students are at risk of digital eye strain during remote instruction, says Dr. Steven Rhee of Hawaiian Eye Center. Rhee suggests that students take a screen break every 20 minutes, for at least 20 seconds. He calls it the ‘20-20-20’ rule - for every 20 minutes up close, take a 20-second break and look at an object that’s at least 20 feet away. That’s sound advice for anyone staring at a screen for hours on end -- students, teachers or parents. Frequent breaks may be a tough ask sometimes, though 20 seconds is generally enough time out. The ciliary muscle is what helps eyes focus on objects at different distances, and too much use leads to that eye strain. The good news is that pain or discomfort felt in the moment is not permanent, even with children in the virtual classroom. But it is something to add to your list of things to remember to do!
