Google Announces Smart Contact Lens Project For Diabetics 90

An anonymous reader writes "Google has announced on its official blog that it's working on a new way for diabetics to monitor their blood sugar: a 'smart' contact lens. Diabetes is a difficult condition to treat because blood sugar levels vary widely by a person's activity level and food intake. It's also hard to monitor without painful and intrusive measurements — people can feel normal at dangerously high blood sugar levels, while extremely low levels can impair their ability to seek treatment. Google says, 'Over the years, many scientists have investigated various body fluids—such as tears—in the hopes of finding an easier way for people to track their glucose levels. But as you can imagine, tears are hard to collect and study. At Google[x], we wondered if miniaturized electronics—think: chips and sensors so small they look like bits of glitter, and an antenna thinner than a human hair—might be a way to crack the mystery of tear glucose and measure it with greater accuracy. We're now testing a smart contact lens that's built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material. We're testing prototypes that can generate a reading once per second.' They're talking with the FDA and bringing in experts to help them figure out the best way to do it."

      Interesting. I'm diabetic and I've never heard of anyone behaving this way due to a low. Personally, I start shaking, I get weak, my heart starts pounding, and I break out in a sweat. The only thing I feel like attacking is a bag of gummy bears.

        As a diabetic, if it sets on slowly then I find grumpyness to be a potential symptom. But there is a another consideration. OK I hate gummy bears, but to use your analogy. There is always one person I feel like attacking during a low. That is the person standing in between me and the gummy bears who won't get out of the way. Now add to that a simple preference of mine, and a predilection. When I do get a low odds are that it is a little before I sit down to eat. Given a choice, I would prefer to eat real food to treat a low rather then a "snack". So anyone who is in someway interfering with me preparing my meal, or sitting down to eat it, is gfoing to ghet there ass reamed.

        Diabetic here too. My experiences with lows are similar to yours. I've spoken to other diabetics that have said that they have been found having an argument with a wall about whether they should have orange juice or not. Your brain can do weird things when starved of glucose.

          That's no lie. The lowest I've ever gotten was 31. I went to my kit and checked myself, then proceeded to grab a needle and my novolog and give myself a shot! Suddenly I thought, "Wait a second. That's not what I want to do," and I reached for the bottle of glucose tabs instead. It was like my brain knew I was supposed to do something, but didn't quite know exactly what.

      No, the design for these contacts does not feature a display at present, and the most they're thinking for the future is something along the line of a single LED light (and I don't exactly see how that would work--if it's over the part of your eye that you can actually see, won't it blind you / seriously impair your vision when it goes off?

How many photons hitting the retina is enough to blind you, given that the human eye is capable of observing single photon events? I believe that much of the eye's dynamic range is due to the iris, is it not? In which case, the light source would have to be dead-center over the iris or risk getting filtered out.

            The problem is focus, i suppose, but i'm not so sure how it works with i.e. google glass if you must watch something that you have pretty close to one of your eyes and other things far at the same time. In the other hand, if instead of dirt would be a section of your glasses tinted blue, would you notice it? Should not be something to be read, with sharp borders, and blocking vision, just something that must be noticed.

              It's like with EVFs on digital cameras, or HUDs in airplanes. You use lenses to make the picture appear to have the same angular size, but much larger distance.

      I don't have diabetes but I am fairly close to somebody who does have diabetes. Having a continuous log of sugar levels is something that is VERY useful in treating the condition. Sure, just having an alert would certainly be useful, not but really sufficient.

      One issue I see with contacts is that they can't really be left in 24x7 without increased risk of complications. Of course, many people do just this all the same. Blood sugars dropping during sleep is definitely a scenario that you'd want your sens

    This is a lot more realistic than the ever-repeating "display integrated into a contact lens" stories. Continuous, non-invasive monitoring of blood sugar will be an enormous boon, especially if it can be integrated with insulin-pump control.

    Having said that, though, wearing a contact lens actually is kind of invasive. I wore them happily for many years, but there were also periods where it wasn't a very happy experience. Contacts do increase certain risks to your eyes, and diabetics already face significant risks to their vision. (As far as I know, the cornea-related risks from contacts are independent of the retina-related risks from diabetes.) I can imagine many diabetics wouldn't be very enthusiastic about wearing a contact lens, especially if they don't need it for vision correction.

    • by reebmmm (939463)

      Diabetic here. I would wear the contact lens in a heartbeat. The idea is that this device would replace the finger pricks, otherwise known as holes in skin. And when you repeatedly test on your fingers (6-10/day), that's a lot of holes and a lot of blood. There is risk for infections, scabs and blisters. And long time diabetics develop callouses on their fingers from testing which means that they need to poke deeper to get blood.

      Plus the checking isn't really "constant." You have to periodically check

    This would be an excellent development, bit keep in mind the field is littered with many dozens of failed devices and startup companies.

    Of the various http://en.m.wikipedia.org/wiki/Noninvasive_glucose_monitor [slashdot.org]"> non-invasive glucose monitoring methods that have been tried, I am aware of only one that was approved in the US (a transcutaneous electroporation device), and that one was withdrawn from the market shortly after.

    Shouldn't they first determine if tears are an accurate way to measure glucose in the first place? That could be measured now, even if it would not be convenient. It would seem that if you are willing to wear a micro sensor in your eye, why not just inject it under the skin? If you did that, you could make it the size of an rfid tag.

    • by wcrowe (94389)

      I wondered about this myself. I'm skeptical that tears are as accurate as blood testing.

      Too right. A box of testing strips for my glucose monitor is £25 for 50 (about $40). Lancets are a lot cheaper, but combined it costs 60p ($1) every time I give myself a blood test.. and that's assuming I can do it first time. OK, I don't have to pay for those (I'm in the UK and the NHS pays) but *somebody* has to pay and GPs are increasingly reluctant to renew prescriptions for patients such as myself who are not on insulin.
  • It's nice to wake up to something like this--people doing good work that could help a lot of people. Even if the particular project fails (if, for example, you cannot measure blood glucose in the tears), the advance in miniaturization and implementation of a contact lens based solution will have a lot of applications.

    Then I read all the AC comments about how much this sucks and they don't want it to succeed, because "Google bad!". Screw you guys.
