I'll believe it when I see it.  I completely trust that the technology is there it just always seems to get bought up and disappear.  I worked on a project with Glucolight in 2006 (do a web search on archive.org) and the had a working optical model back then.  The patents have been around a long time.  UT Austin had some of the early ones.  There are several different non-invasive techniques and they usually involve some kind of optical or other RF frequency shift to measure the vibrational frequency of the blood.  See OCT, Raman spectroscopy, etc. for the basics.  Here is a simple test: Does the glucose test involve a consumable that the user has to constantly buy?  If yes then it will come to market.  Does the device run without requiring that calibration devices or consumables will be needed for use?  If yes then it won't make it to market.

I've been T1D since birth. This would be amazing but I fear for the accuracy. As it stands the current CGMs available to us aren't 100% accurate 100% of the time, and that's with being subcutaneous. Not sure how a wrist watch could possibly give accurate readings without a blood sample. Just a targeting ploy and I'm sure it wouldn't be cheap.

Yeah nop head, it was my idea and you know it

Nice they totally took my idea. I was developing one with an optical sensor.

Then provide documentation, links  or pictures about your so-called idea, if u can't reply accordingly then please don't put brainless comments here, thank u.
