Forget the finger-prick blood test. The South Korean research team POSTECH have developed a smart light-emitting diode (LED) contact lens for diabetic DIAGNOSIS, MONITORING and retinopathy TREATMENT 👁
🔸
The transparent contact lenses have micro-LEDs and photodetectors built in. This allows it to measure glucose concentration in the conjunctival blood vessels by analysing the NIR light to give a accurate blood-sugar reading in real time!
🔸
Many people with Type 1 and Type 2 diabetes monitor their blood glucose level to help to manage their condition and reduce the risk of health complications such as amputation and blindness. This disruptive technology could potentially change the the way diabetics - who prick their fingers as many as 10 times daily - get diagnosed, monitored, and treated.
🔸
The wireless smart contact lenses are made using the same material used in commercial soft contact lenses. The only small visible feature is a micro LED display. The electrode and base of the wireless smart contact lens are see-through and do not obstruct the wearer’s vision.
🔸
Professor Hahn said: “We developed a smart LED contact lens that can diagnose diabetes and treat diabetic retinopathy with light for the first time in the world. We are planning to commercialise these smart contact lenses and smart wearable medical devices in collaboration with Stanford Medicine.”
