Researchers from Korea's KAIST institute, in collaboration with researchers from Seoul National University, POSTECH and ETRI, have developed wirelessly-powered ophthalmic diagnostic contact-lenses based on OLED devices.
The contact-lenses use the Electroretinography (ERG) ophthalmic diagnostic method that measures whether the retinal function is operating normally. ERG is widely used for the diagnosis of hereditary retinal diseases and assessing retinal function decline. Conventional ERG uses large device that requires the patient to keep their eyes open, and remain still in a dark room. The new device, based on a flexible OLED, is much more comfortable and easy to use.
Such contact-lenses could also find application in areas such myopia treatment, analysis of ocular bio-signals, AR and light-based neural stimulation in the future.
