EyesRhythm is an offline desktop companion designed to help software engineers, designers, and other screen-focused professionals maintain a healthy blink rhythm. Developed by a research engineer with 20 years of computer vision experience, the tool addresses digital eye strain caused by reduced blink rates during focused screen time. The application uses webcam technology to score blink frequency and regularity, calculating an Ocular Rhythm Index from 0 to 100. Beyond blink detection, it tracks neck movement via a visual log called Poise, alerting users to head positioning that may cause shoulder strain. The software operates entirely on-device with no cloud data transmission, ensuring user privacy. It features visual and audio alerts, a two-minute practice coach to build muscle memory, and a dockable GUI for settings and reports. The tool aims to prevent long-term discomfort by encouraging healthy habits, though lasting issues should be addressed by eye-care professionals.
The companion addresses the common issue of reduced blink rates during focused computer use, which can cut blink frequency in half. By monitoring both rate and regularity, EyesRhythm helps users avoid the bursts and droughts of sparse blinking that lead to dryness and fatigue. The system provides gentle nudges through visual orange pulses or sound alerts, with optional beeps on each blink. A neck movement tracker called Poise uses a dial interface to show head direction, encouraging users to move their neck and shoulders through various ranges of motion to relieve tension while working.
EyesRhythm represents a practical application of AI and available libraries to solve a profession-specific health issue. The developer's personal experience with irreversible eye strain from 20 years of research engineering informs the tool's design. The application stays beside the work rather than adding another dashboard, focusing on minimal disruption while monitoring ocular health. With features like live graph tracing and face tracking using multiple webcams, it offers comprehensive monitoring for those spending long hours at screen-based workstations.
