Why?
Humans normally blink about 15 times in one minute. However, studies show that we only blink about 5 to 7 times in a minute while using computers and other digital screen devices. Blinking is the eye’s way of getting the moisture it needs on its surface.
Take regular breaks using the “20-20-20” rule: every 20 minutes, shift your eyes to look at an object at least 20 feet (≈ 6 metres) away, for at least 20 seconds. This rule is recommended by the American Academy of Ophthalmology, the UK National Health Service, the Canadian Association of Optometrists and many other health institutions.
How it works?
This app reminds you to take regular 20-second breaks, every 20 minutes. To do so, it sends you notifications every time you need to take a pause, and a reminder to get back to work once the 20 seconds elapse.
To do so, you need to allow the app to send you notifications. You can check your notifications settings for Google Chrome here, or for Mozilla Firefox here.
