As a type 1 diabetic, it can be quite annoying and sometimes painful to monitor my blood sugar multiple times a day. Finger pricks still hurt no matter how often you've done them. Recently, I've gotten a small medical device developed by Dexcom that will monitor my blood sugar once every 5 minutes. It is attached to my stomach with a wireless transmitter which sends data to a device about the size of an iPod which I keep in my pocket. It alerts me when my blood sugar is going too high or too low. It has greatly improved my blood sugar control.
Then today, I read an article on Reuters stating that Google is testing a new prototype contact lens which has a small glucose sensor as well as a transmitter built in. I'm incredibly excited about this advancement. I realize that this will first have to go through many years of testing and approvals, but if it does, it will be another great step forward in making controlling my blood sugar more convenient.
While I love that Google is getting into the medical field more and more, I'm wondering at what cost this will be. Will they be collecting glucose information not only for the user but also sell this information somehow (although I'm not sure if that would be worth anything)? Maybe I'm just being paranoid that Google always has the ulterior motive of analytics regardless of what it gets into. I'm just hoping they are getting into the medical field more so for the betterment of society and of course to make a profit, but that's ok with me.
