>Measuring blood glucose with contact lenses? How? Lag time is around one hour for eye liquid. Your are dead and the sensor does not know it yet. Your need to be below 10 min lag time.

Why? What if you don't care about having your blood glucose data that quickly, and just want to see the overall trend, even if it is delayed an hour? This won't help people who really need to be able to see what their glucose level is right this second, but for others it's a lot more convenient than having to prick yourself every morning.

If the lag is one hour, you still need to prick.

If you want to see "overall trend" and don't care about any "lag time", just measure in Urine.

There is an enormous difference between ease of use of a contact lens sensor that you presumably wear most of your awake time and that gives you constant stream of measurements with 1h lag and urine test kit that you carry with you and with luck remember to use every few hours.

Yeah. As a non lens wearer sounds pretty comfortable to me.

But if you have money I can offer you a non-invasive glucose measurement start-up with peer reviewed publications.

I wear contact lenses. If I could instead wear lenses that continuously monitored my glucose level and it didn't cost me anything extra, and they still gave me the visual acuity of my normal lenses, why wouldn't I use that? I already wear them every day so for me, it requires zero effort.

Having to get urine samples regularly, or worse, blood samples, is a LOT more work on my part (not to mention painful for the blood samples), so it's not something I'm as likely to want to bother with.

"it didn't cost me anything extra" Good luck with that.

How about people walking abound 24/7 with an anal plug?

Wow, that's an incredibly asinine comparison and comment. Millions of people walk around with contact lenses every day, myself included, and don't find them uncomfortable at all (or at least, much more comfortable than glasses). If they had an additional useful feature built into their lenses for no extra cost, I'm sure plenty of them would be happy to have it. If you don't like contacts, that's your issue, not mine.
