Pretty sure its not a pressure sensor at all. just a strain gauge-like thing on the cornea, outside the eye. so its inferring pressure from cornral strain, which is pretty much what they do in the office with the air puff or goldman tonometer. patient to patient variability might be big, but MDs can at least monitor relative changes.

Ditto, details on the sensor are left out in the article... probably a type of membrane pressure sensor with nanowire array embedded in it? MP Divakar

Interesting! The way this lens gets power and communicates data is very interesting. This is the basic principle being used in NFC. But I didn’t get it how does the lens senses the ocular pressure? It mus use some very special strain gauges.

a very innovative solution indeed. Can a similar device be developed for blood pressure monitoring of a patient because in this case also the BP measured by the doctor in his dispensary is always different (normally higher) than the BP while doing normal household activities
