I’m Kazuo Tsubota.
I work at Keio University’s Department of Ophthalmology and the Health Science Laboratory.

In the study of dry eye, we focus on blinking. When we blink, we create a new “ocean” over the surface of our eyes. When you blink less frequently, like when you’re using a computer, your eyes dry out. When the eyes get dry, the compensation mechanism goes into effect, moistening the eyes by increasing the blinking rate. By measuring this we can grasp the state of a person’s dry eye.

We check our blood pressure ourselves, and now we’ll be able to check our eyes. JINS MEME has tremendous potential for what we call self-checks and self-monitoring. This is a field of the future, so I can’t say for certain, but I think JINS MEME will produce the parameters that we’ll need to gain insight about ourselves. For example, hospital patients wait in a lobby. This waiting time has always been a waste, but it would be interesting if we could have patients wear these glasses to complement diagnoses of dry eye and allergies based on the information we glean from them reading the newspaper, watching TV and chatting as they wait.

When a person wears JINS MEME, you can learn about their lifestyle from eye position and movement data. When he or she falls asleep, the eyes stop moving. When dreaming during REM sleep, they begin moving. With JINS MEME, we can assess the person’s internal clock 24 hours a day. A device like this is truly amazing.

I’m an ophthalmologist, so I see the world through the eyes. I think it will be amazing if through JINS MEME and eye information, we can see and study a person’s overall health in its entirety.

Kazuo Tsubota

A Chairman & Professor of Ophthalmology, Keio University School of Medicine, after graduating from the same school in 1980, Tsubota acquired medical licenses in Japan and the United States. In 1985 he studied abroad at Harvard University and completed a clinical fellowship studying the cornea in 1987. He immediately turned his attention to dry eye, a so-called modern-day affliction. Tsubota has endeavored to provide high-quality medical treatment, including the development of new methods for corneal transplantation. Since 2000 he has studied cutting-edge anti-aging medicine and actively introduced it into the medical field. Tsubota continues to research while giving importance to proper food, exercise and mental wellbeing.
