How does 20 work?

The 20-20-20 rule is a simple technique used to reduce eye strain caused by prolonged screen time. It involves looking away from your screen every 20 minutes and focusing on something 20 feet away for 20 seconds.

This technique is based on the idea that looking at a distant object can help reduce eye fatigue by allowing your eyes to relax and focus on a different visual target. The 20-20-20 rule is often recommended by eye care professionals as a way to reduce eye strain and promote eye health.

Research has shown that the 20-20-20 rule can be effective in reducing eye strain, but it may not be enough to completely eliminate eye fatigue. It’s also worth noting that the 20-20-20 rule is not a substitute for regular eye exams and proper eye care.

The Charlotte Observer article discusses new research on the effectiveness of the 20-20-20 rule, but it does not provide specific details on how to implement the rule or its long-term effects on eye health.
