The 20-20-20 rule is a guideline designed to reduce eye strain caused by prolonged screen time. According to this rule, every 20 minutes, you should take a break and look at something at least 20 feet away for 20 seconds. This simple practice helps relax the eye muscles and can prevent discomfort. Implementing the 20-20-20 rule is easy and can be done anywhere, whether you're working on a computer, using a tablet, or watching television. By incorporating this rule into your routine, you can promote better eye health and maintain comfort during extended periods of screen use.
