Chrome: We’ve discussed the 20-20-20 Rule before, where every 20 minutes you take a 20 second break and look at an object 20 feet away to relieve eyestrain and rest your eyes. The 20 Cubed add-on for Chrome will automatically remind you to take those breaks so you don’t have to set your own timer.
20 Cubed doesn’t do anything your phone or a stopwatch can’t already do, but if you’re busy at work already, it’s easy to forget to set a timer or keep an eye out for how long it’s been since your last eyestrain break. Once installed, 20 Cubed lives in the Chrome toolbar, and it will prompt you when it’s time to take a break. If you’re curious, you can click it at any time to see how long until your next break.
There isn’t much more to the add-on than that, but it’s a great way to remind yourself to rest your eyes every now and again, especially if you already work in Chrome all the time. For more ways to reduce eyestrain, check out our tips to keeping your eyes safe.
