Researchers at UK based Lein Applied Diagnostics are developing a diabetes device that can read blood sugar levels by just scanning the eye.
The mobile phone-sized device, which uses advances in optical communications, shines light into the eye and interprets the optical changes rather than chemical changes.
The software then interprets the readings and displays blood sugar levels as well as the amount of insulin needed to be injected.
According to researchers, this optical device is intended to improve diabetes control, eliminate the pain of finger pricking and reduce NHS costs.
Lein director Dan Daly said clinical trials of the device are being conducted locally.
"We then face another year of engineering and up to two years of further clinical trials," Daly said.
