So far, we know the 6-6-6 rule for walking, but there is something new for eye health too. It is called the 20-20-20 rule. In our day to day lives, our screen time has increased, in fact, screens have become an integral part of our life, which means we must take extra care of our eye health and this 20-20-20 rule will help you. What Is 20-20-20 Rule?This rule says that for every 20 minute that you spend on looking at the screen, you must take a 20 second break to look at something 20 feet away. While you won't know how far is 20 feet from your desk, the key is not to actually stand 20 feet apart, but to take a break from your screen and be far from it, especially if you have a smaller work space and don't have the time to roam around. You can set an alarm every 20 minutes to remind yourself for a well deserving break that you deserve. Is the 20-20-20 Rule Supported By Research?The American Academy of Ophthalmology says that looking at digital devices won't necessarily damage your eyesight, but it can cause strain and unpleasant symptoms. Humans usually blink around 15 times each minute, and when we stare at our screens, the frequency decreases half or a third. This is why our eyes feel dry, irritated, and we feel that our eyes are getting tired.
