LUMES 20-20-20 is a Google Chrome extension that can help to reduce eye strain and boost productivity by prompting you to take regular breaks from the screen. The default settings are 20 minutes work with 20 seconds rest based on the 20-20-20 rule recommended by eye doctors.
What is the 20-20-20 rule?
It’s quite simple, really. The 20-20-20 rule recommends that people using digital devices should look at something 20 feet away for 20 seconds, every 20 minutes. The hard part? Remembering to look away.
