BlinkGuard · Blink Reminder, Eye Strain Relief & 20-20-20 Timer

Blink reminders and a 20-20-20 eye break timer that fight eye strain, dry eyes & screen fatigue. Free. No account, no tracking.

Eye strain, dry eyes, and tired eyes after a long day at a screen usually come down to one thing: when you focus on a screen, your blink rate drops by more than half. Fewer blinks means less moisture, so your eyes end up dry, gritty, and fatigued. BlinkGuard is a gentle blink reminder and 20-20-20 eye break timer that keeps your eyes comfortable through long work, study, and screen sessions. At an interval you choose, BlinkGuard shows a soft, non-intrusive cue that nudges you to blink fully a few times and look away from the screen. No pop-ups, no noise by default, nothing that breaks your focus. Pick the style that fits your room and your work, then carry on. It is a simple way to fight eye strain, dry eyes, and computer eye fatigue, and to build a healthier screen habit around the 20-20-20 rule that eye care professionals recommend: every 20 minutes, look about 20 feet away for 20 seconds.
