No More Poking: Smart Contact Lens Measures Blood Glucose

If you have diabetes, you know what a hassle it can be to constantly have to test your blood glucose levels. However, no matter how annoying it may be, it simply must be done if you expect to stay in good health. Trust me, I totally get not wanting to poke yourself repeatedly with a sharp pointy thing to retrieve a bead of blood, but the alternative is an emergency trip to the hospital or, worst case, diabetic coma or death.

Over the last several years, the medical profession has improved testing methods by leaps and bounds, but pretty much all of them still require that tiny amount of blood. Not so any more! These are contact lenses, which monitor blood glucose without the need to bleed. I would imagine that is huge for those of you who have to test multiple times per day.

Google[x] developed these, and while they are still a prototype right now, they will be coming. How they work is you wear them just as you would any other contact lens, but instead of vision correction these have sensors and a tiny wireless chip embedded in them. The sensors constantly read your blood glucose levels, and the chip transmits the results to an app. They are also developing a way that the lens itself would contain tiny LED lights that warn the user when glucose levels are in need of adjustment.

As I said, this is still a prototype. But Google[x] is actively seeking partners to help them put these in the hands of consumers sooner rather than later. It also wouldn’t surprise me if they were planning to develop a lens that includes vision correction as well as glucose monitoring, which would be doubly helpful.
