Why it exists

Your eyes work hard for you. Screens make them work worse.

Focused computer use often cuts blink rate in half. Sparse, uneven blinking is a known driver of digital eye strain, dryness, grit, fatigue, blurred vision, and it is easy not to notice until the eyes already hurt. EyesRhythm is a blink rate detector that sits beside that work.

What rhythm means

Rate and regularity, together.

Rate is how often. Regularity is how steady. Enough blinks can still arrive in bursts and droughts; a slow but even pattern still leaves the surface dry. EyesRhythm folds both into the Ocular Rhythm Index (0 to 100). Maximize your healthy desk ORI, use practice daily, it helps to build muscle memory.

FAQ

Questions, answered.

What is a blink rate detector?

A blink rate detector uses a camera to notice each blink and measure how often they happen, usually as blinks per minute. EyesRhythm does that on your Mac or Windows computer, then also looks at how evenly those blinks are spaced.

Does EyesRhythm work with a laptop webcam?

Yes. It uses the built-in camera on a Mac or Windows laptop, or a USB webcam. Sit as you usually work so the camera can see your eyes. The setup guide in the journal walks through the few things that help.

Does any video leave my computer?

No. After you register the license, frames are read on this machine and discarded. There is no account, cloud, or analytics. Camera frames are not uploaded or kept as a film of your face.

How is this different from a blink counter?

A counter only totals blinks. Six blinks can still mean two very different minutes if they arrive in clumps with a long dry wait in the middle. EyesRhythm folds rate and regularity into one Ocular Rhythm Index, from 0 to 100.

Is EyesRhythm a medical device?

No. It is a wellness companion for desk work, not a diagnosis or a treatment. Lasting discomfort or a change in vision belongs with an eye-care professional.

About

Built from a real pain, not a trend.

The developer behind EyesRhythm has spent more than two decades working as a software developer. Years of long hours in front of computer screens gradually took a toll on his eye health, leading to frequent dryness, redness, and, at times, significant discomfort.

Advances in modern technology made it possible to create EyesRhythm: a simple, lightweight companion designed to support healthier blinking habits during extended screen use. Having personally used the application, he has found it useful and effective enough to share with others.

Our goal is simple: to build technology that solves a real problem without creating another distraction. EyesRhythm works quietly in the background, helping users become more aware of their blink rhythm while staying focused on their work.

We believe the best products are shaped by real experiences and honest feedback. If you choose to try EyesRhythm, we would greatly appreciate hearing about your experience at hello@eyesrhythm.com. Your feedback will help us continue improving the product and ensure that it remains simple, useful, reliable, and unobtrusive.
