A quiet cue — not a lecture.
Stays beside the work. Counts only while you are at the screen.
Why it exists
Your eyes work hard for you. Screens make them work worse.
During focused computer use, people blink far less often than they do in conversation. That drop is a well-known driver of digital eye strain: dryness, grit, fatigue, and blurred vision.
The problem is not that you “forget to care.” Attention narrows, the face stills, and blinking becomes sparse and uneven — and you rarely notice until the eyes already hurt.
What rhythm means
Rate and regularity, together.
Rate answers how often. Regularity answers how steady. Either one alone is incomplete: enough blinks can still arrive in bursts and droughts, and a perfectly even but very slow pattern still leaves the surface under-refreshed.
EyeRhythm folds both into the Ocular Rhythm Index — a 0–100 glance for “is my blink cadence supporting me right now?” A healthy desk cadence is often around 15–20 blinks per minute.
The companion
It watches, scores, and, if you ask, gently nudges.
Live rate, regularity, and ORI on a compact window. Optional alert if ORI stays low for a meaningful stretch — not a single bad second. Optional beep on each counted blink. Practice is a two-minute full-screen coach so the habit is easier to feel, not only to measure.
It is a wellness companion, not a medical device. Persistent discomfort or a change in vision belongs with a licensed eye-care professional.
