Show HN: An offline desktop companion to help maintain a healthy blink rhythm

EyesRhythm is an offline desktop app that uses your webcam to monitor and improve your blink rate and consistency during screen time, addressing digital eye strain caused by reduced blinking. The tool tracks blinking patterns in a live graph, provides an Ocular Rhythm Index score (0-100), and offers gentle alerts and a two-minute practice session to help build healthier blinking habits, while a companion feature called Poise encourages head movement to relieve neck and shoulder tension. All processing occurs locally on your device with no data sent to the cloud or accounts required.
