Google contact lens 'could end blood testing for diabetics'
Google has unveiled a prototype contact lens that monitors glucose levels in tears and could one day replace traditional finger prick blood tests undertaken by diabetics.
Google 'Smart' lenses look and feel like regular contacts
The Google 'Smart' contact lens that monitors glucose levels in tears "looks and feels" like ordinary soft contact lenses, said lead researcher Brian Otis.
"This prototype looks and feels like a regular soft contact lens but inside it we have a tiny chip and a miniaturised glucose sensor that allows us to continually monitor tear glucose levels," he said.
"We've had to work really hard to develop tiny low-power electronics that operate on very low levels of energy and really small glucose sensors."
