The 20-20-20 Rule: Sanctuary's 20-20-60 Reset
Sanctuary's current reset is 20-20-60: every 20 minutes, stop screen work, look about 20 feet away, and follow a 60-second guided breathing reset. It may help interrupt prolonged near-focus and remind you to look away, but it is not a treatment for persistent eye pain or vision changes.
What to remember.
Use 20-20-60 as a recurring break cue, not a medical treatment.
Looking across a room is a practical substitute when 20 feet is hard to measure.
Persistent pain, headaches, double vision, or vision changes warrant professional advice.
The useful detail.
Why this matters in practice
The reset works as a habit cue because it arrives inside the focus session you already started. You do not have to notice fatigue, decide to stop, or talk yourself into the break; the loop carries you there.
Where 20-20-60 came from
The origin is the classic 20-20-20 rule: every 20 minutes, look about 20 feet away for 20 seconds. Sanctuary keeps the 20-minute cadence and the 20-foot look-away, then extends the rest to a full 60 seconds of guided breathing for a clearer return to work.
How to use the 20-20-60 reset
Set a quiet reminder for every 20 minutes of screen work. When it appears, stop reading, relax your gaze, and look away from the screen while you follow the 60-second breathing cue. The useful behavior is breaking continuous close focus; exact distance measurement is less important than choosing a genuinely distant target.
What the reset does not prove
The reset is a low-risk comfort habit, but the exact 20-minute and 60-second intervals are not a guarantee against digital eye strain. Screen comfort also depends on lighting, glare, text size, viewing distance, blinking, corrective lenses, and underlying eye conditions.
How Sanctuary supports it
Sanctuary pairs focus periods with a 60-second eye rest and guided breathing. The cue is designed to help you keep the habit; it does not diagnose, prevent, or treat an eye condition.
Direct answers.
What is the 20-20-20 rule?
The 20-20-20 rule is a memorable eye-break cue: every 20 minutes, look about 20 feet away for 20 seconds. Sanctuary keeps the 20-minute cadence and look-away, then adds a 60-second guided breathing reset.
Does the 20-20-60 reset prevent eye damage?
It is a comfort and break-taking habit, not proof of prevention and not a substitute for eye care.
What if I cannot see something 20 feet away?
Look toward the farthest comfortable point in the room or out a window and let your near-focus relax.
