Google X Lab unveiled a smart contact lens that can help diabetics to measure their glucose level in tears on 17 January 2014. The smart contact lens has been developed in collaboration with the US Food and Drug Administration (USFDA) by Brian Otis and Babak Parviz.
The contact lens uses a tiny wireless chip and a minituarized glucose sensor. Besides it uses an antenna, thinner than a human hair, to measure tear glucose with better accuracy. The lens also uses tiny LED lights to warn users when their glucose levels cross certain thresholds.
The company is currently testing prototypes of contact lens that can take about one reading per second.
According to the World Health Organization (WHO), diabetes affects 347 million people worldwide. In 2004 alone, 3.4 million people died as a result of high fasting blood sugar.
The International Diabetes Federation data shows that one in ten people across the world's population are forecast to have diabetes by 2035.
