No Fibs — Honest Limitations
The 20-20-20 rule is a popular heuristic, not a clinical prescription — evidence that it prevents lasting eye damage is weak; what's well-supported is that blinking less and staring at near distances contributes to temporary digital eye strain (dryness, ache, blur). Regular gaze breaks and conscious blinking reliably relieve those symptoms. Persistent pain or vision changes are an eye-doctor visit, not a timer. Breaks count saves only in your browser.
