Lab on a Contact Lens Can Measure Stress Through Serotonin

short sci-fi horror story follows:

* Hello, we've called you to HR because we've detected you have been stressed at work.

- Sure, some... overwork status after you reduce headcount, but nothing it isn't being managed with the hierarchy chain.

* Glad to know. Be sure we, as a company, endeavour to have a stress-free workplace. You will be put in a Stress Workplace Reduction PIP, just as a formality of course; since you mentioned you have taken the appropriate steps to reduce stress you should pass the PIP, no need to stress about it! See you in a few weeks.

- Er... Thanks......?

Fascinating! How does the data make it off the lenses? Graphene-scale radios on my eyes sounds like it would have to have side effects.

This will come handy for my Voight-Kampff testing machine startup.

Meanwhile the Apple Watch can't even measure glucose levels.

How useful is detecting seratonin?
