How often have you used a screen for hours, only to find your eyes feeling strained, tired, and sore? Especially with the pandemic we’re all working and studying using our computers more than ever before, and because of this eye care is even more important than normal. To protect your eyes when using screens, you may have heard of the 20-20-20 rule. What this means, is that you should look away from your screen for 20 seconds every 20 minutes, to a distance of 20 feet or more. This helps relax your eyes, and helps ward off eye strain.
Remembering to do this every 20 minutes sounds difficult, right? That’s what the Arduino Eyesight Guardian is for! This unobtrusive little gizmo clips over the top of your monitor, and every 20 minutes gives you a reminder to look away for those recommended 20 seconds. It takes USB power from your computer, and has a tiny push button for you to register when you’ve looked away, so it’ll reset the clock and sleep until the next reminder is due.
