Google's contact-lens technology is one step closer to helping diabetics better manage their condition. The key goal behind the technology is to help people with diabetes. Currently, those with diabetes must prick their skin throughout the day to check their blood glucose levels, a task that can be time-consuming and painful. But without the constant monitoring of their blood glucose levels, diabetics can put themselves at risk with potential damage to the eyes, kidneys, and heart. As a less invasive solution, Google's smart lens technology would continuously measure the tear fluid in the eye to track the glucose levels. Those readings would then be sent wirelessly to the user via a mobile. Smart contact lenses are developed by Google and Novartis' eye care division Alcon. The smart lens technology could also be a boon to people with presbyopia, a condition in which the eye loses its ability to autofocus, rendering people unable to see objects up close.
