Contact lens to monitor diabetes


Google is not only a search engine, it is also making health innovations. The Google[X] lab has created something called a smart contact lens which will help track blood glucose levels for diabetics. Instead of having to  prick a finger for diagnosis, the info can be read off the lens. The lens is equipped with chips and sensors so small they look like bits of glitter, and an antenna thinner than a human hair. They also want to add tiny LED lights that would flash if glucose levels are abnormal.

The soft contact lens is still just a prototype, but it will measure the glucose levels in tears. There is a pinhole in the lens that allows tear fluid to drip over the glucose monitor. According to Google, the lens takes a reading once every second.The data will be collected from the lens to a device to read and analyze the levels.

If it reaches market, the lens could be of use to the large number of Blacks/Africans who are diabetic. According to WHO, more than 80% of diabetes deaths occur in low and middle-income countries which most African countries constitute.

It is always exciting to learn about new health innovations and it is our hope that these lenses would be affordable in lower income countries for those who may need them.
