Smart contact lens for diabetics? What’s next for digital healthcare
22 Jan, 14 | by BMJ
Diabetics could soon avoid pinprick blood tests using a smart contact lens that measures glucose in tears. A prototype shown off by Google (with a little help from Microsoft) uses an embedded miniaturised glucose sensor and wireless chip to measure glucose levels as often as once every second.
“We’re also investigating the potential for this to serve as an early warning for the wearer, so we’re exploring integrating tiny LED lights that could light up to indicate that glucose levels have crossed above or below certain thresholds.”
