Ever since the rise in popularity of wearables such as Apple Watches and Fitbits, all the giant tech companies decided to be over-ambitious and started fantasizing about some great technology they could invent in the future. One of the inventions Google thought they could invent was a contact lens that could measure blood glucose levels.
Monitoring blood levels in tears proved too inaccurate.
Google recently announced that they might have jumped the gun thinking they could invent blood testing contact lenses and aborted the mission. While the project had some success in the lab, the ability to monitor blood levels in tears proved too inaccurate.
With this news, a tear was shed by endocrinologists everywhere as such a non-invasive device used to measure blood glucose would have been the pinnacle of human innovation.
On the other hand, optometrists and ophthalmologists around the world rejoiced because that would have been thousands less corneal ulcers to treat from contact lens over-wear.
