Does anyone know anything about this?

Only a color change is not worth a big thing, if it doesn't give you the concrete figure .., and the eyes like Chiribitas, pfff, and you can't even see them yourself ..

I believe that this invention was monitored, with mobile or clock if it would be more complete since it would give you more data

They give little info there.I imagine that the color change looks at oneself.It is true that without knowing the value it is of no use, but the same if it gives the value in some way.

As they say so little, I wanted to know if someone here was aware of these slows and could explain something else.

Thank you :)

Hello @emily these lenses were a Google prototype that has had to close the project due to problems in the consistency of glucose values.They had managed to introduce technology into the lentilla, but the values ​​did not approach and as a health product did not meet the requirements.
It is a shame, but it was seen coming that it was not going to be precise.I imagine that the technology that has been developed to create this type of lenses will use them for other projects.
All the best :)
