The OLED contact lens-based ERG test could be the first of its kind in the world.
Researchers from South Korea have created what could be the world’s first light-emitting contact lens for retinal diagnostics.
Seoul National University Bundang Hospital (SNUBH), the private Pohang University of Science and Technology, biopharmaceutical company PHI BIOMED, and the government-funded Electronics and Telecommunications Research Institute collaborated for this project.
HOW IT WORKS
An ultra-thin (approximately 12.5 micrometre) OLED is attached to a contact lens electrode. They used OLED, which uniformly emits light, as electroretinography (ERG) tests require even illumination across the entire retina to measure its electrical activity and assess its function. The contact lens is also embedded with an antenna for wireless power reception...
