Protect your vision and eliminate screen fatigue. Automatic 20-minute interval alarms, soothing audio cues, and guided eye yoga exercises.
Automated focus relaxation, tear renewal cues, and fatigue index scoring
Every 20 minutes of screen work, alerts you to gaze at an object 20 feet away for 20 seconds to relax ciliary focus muscles.
Step-by-step guidance for distance focusing, 20-blink tear refresh, figure-8 tracking, and warm palm cupping.
Soothing Web Audio chimes signal the exact moments to pause work and return to your screen.
Continuous near-point screen focus locks eye muscles into focal fatigue. Looking 20 feet away allows full optical decompression.
Rhythmic complete blinking spreads lipid oils over the cornea, preventing dry eye evaporation and blurry evening vision.
Gentle darkness and body warmth from clean palms block all optical stimulation, resetting retinal photoreceptor sensitivity.
Everything you need to know about the 20-20-20 Rule & Eye Rest
Endorsed by the American Optometric Association (AOA) and the American Academy of Ophthalmology (AAO), the 20-20-20 rule states that every 20 minutes of screen time, you should look at an object at least 20 feet away for at least 20 seconds.
When staring at digital screens, human blink rate drops by over 60% (from 18 blinks/minute down to 4–6 blinks/minute). This causes the protective tear film on your cornea to evaporate, leading to burning, redness, and strain.
Looking at a close computer screen requires the circular ciliary muscles in your eyes to contract constantly. Gazing 20 feet away relaxes these muscles to their default resting optical state.

Calculates your daily Computer Vision Syndrome fatigue risk score based on work duration and break compliance.
The timer synthesizes gentle harmonic tones using the browser's native Web Audio API at the start and end of every 20-second eye break. Audio can be toggled on or off anytime.
