About 202020
Protect your eyes from digital strain with the 20-20-20 rule, recommended by optometrists worldwide. Every 20 minutes, this extension gently reminds you to look at something 20 feet (6 meters) away for 20 seconds. This simple habit relaxes the ciliary muscles in your eyes, reduces dry eye symptoms, prevents headaches, and helps combat Computer Vision Syndrome — a condition affecting up to 70% of computer users. Stay focused, work longer with less fatigue, and preserve your long-term vision.
