OREANDA-NEWS Korean scientists have designed the world's first OLED-based contact lenses. The invention is described in the scientific journal ACS Nano.
Specialists from the Korea Advanced Institute of Science and Technology (KAIST) have developed lenses based on OLED technology. Their invention can be used in electroretinography (ERG), a diagnostic method that records changes in the bioelectric potential of the retina. In the future, such an accessory can be used as regular contact lenses.
KAIST said that the ERG procedure requires a dark room and special diagnostic equipment. Also, during the process, the patient must sit motionless with his eyes open. The OLED lenses created by scientists can be used for continuous observation of the retina of the eye without causing inconvenience to the patient.
The lenses are based on an ultra-thin flexible OLED display with a thickness of approximately 12.5 micrometers, which is 6-8 times thinner than a human hair. Data from the lens is transmitted wirelessly, and power is supplied via a channel with a frequency of 433 megahertz. During the tests, it turned out that the portable ERG device successfully collected data in low-light conditions.
"This study will help expand the capabilities of smart contact lens technology to platforms for optical diagnostics and phototherapy," said the study's author, Professor Seung—hyep Yu.
In June, it became known that the drug semaglutide, known by the trade names Ozempic ("Ozempic") and Wegovy, can cause blindness. According to scientists from Europe, such a side effect can be detected in one in ten thousand patients.
