blinkwell

blinkwell is an on-device eye fatigue monitor that analyzes blinks and eyelids through periodic camera windows to prompt rest breaks.

Blinkwell is an on-device eye fatigue monitor designed to help protect vision during computer work. Every ten minutes, it opens the webcam for a sixty-second check to analyze blink dynamics, eyelid closure, and partial blinks locally using MediaPipe Face Landmarker. Frames are processed in memory and discarded instantly to maintain privacy, and the camera is released between checks. When fatigue signals rise above a baseline, the software suggests timed, guided breaks such as the 20-20-20 rule, palming, or full-blink exercises. It stores data locally in a single directory on the user machine with no account creation needed.
