Skip the blue-light glasses

👓 Skip the blue-light glasses: They don’t really protect your eyes from screen strain (paywall link). The real issue is looking at your device too closely for too long and forgetting to blink. We normally blink 15 times per minute, but that drops to six times per minute when staring at screens. Try the 20-20-20 rule: Every 20 minutes, take a 20-second break to look at something 20 feet away.
