title: It's All in the Eyes: The eyes as a window to the body and brain may not be a brand-new idea - but it is a newly revitalized one, thanks to improved technologies.
abstract: In a blog post in January 2014, Google unveiled one of its latest forays into the health market?a smart contact lens for diabetics. It was sleek and appealingly futuristic, with a minute microchip equipped with tiny glucose sensors, embedded in a soft, biocompatible lens material. Already, the company said, the prototype could measure tear glucose as often as once per second, and it may someday include tiny LED lights to signal warnings to the wearers when their blood sugar rises or falls to dangerous levels.
