Sightful

A mindful blink reminder for healthier eyes. Privacy-first digital wellness.

Sightful: Optometrist-Backed Blink Reminders for Digital Eye Strain Relief Do your eyes feel dry, tired, or strained after long hours on the computer? Many people tell me their vision gets blurry or they “forget to blink” while working — classic symptoms of digital eye strain. As an optometrist, I built Sightful to gently restore natural blinking patterns using subtle, research-backed visual cues that reduce dryness, fatigue, and screen-related discomfort. Sightful is a privacy-first blink reminder extension designed for anyone who spends significant time in front of screens. Studies show blink rate drops 50–60% during computer use, causing tear film instability, irritation, and dry eyes. Sightful helps maintain healthy blinking habits without interrupting your workflow — and without collecting any personal data. How It Works Sightful uses non-intrusive visual cues that appear at customizable intervals (every 15–30 seconds). When you blink, the cue disappears instantly, creating a natural feedback loop that encourages complete, healthy blinks. All processing happens locally on your device — no camera, no tracking, no data collection, and no network requests.

Studies show: • Screen users blink only 8–9 times per minute (compared to 15–20 normal) • Blink incompleteness increases dramatically during screen use • Over 65% of adults report symptoms of digital eye strain • Healthy blinking is essential for maintaining tear film stability and ocular surface health By restoring a natural blink rate, Sightful helps prevent dry eye symptoms, reduces eye fatigue, and supports long-term ocular wellness — especially for people who spend 6+ hours daily in front of screens.
