Core Viewpoint - The research team from KAIST has successfully integrated OLED light sources into ultra-thin flexible contact lenses, creating a new generation of ophthalmic diagnostic technology [1][3]. Group 1: Technology and Applications - The new technology is expected to be applied in various fields, including myopia treatment, ocular biosignal analysis, AR visual information transmission, and light-based neural stimulation [3]. - The eye electronic system can meet multiple medical needs, including monitoring physiological signals related to vision or other diseases [3]. Group 2: Clinical Utility - The new contact lenses can be used for clinical electroretinography (ERG) testing, which measures the electrical responses of different cell types in the retina [6]. - Unlike traditional ERG diagnostics that require complex setups and dark environments, the new system allows patients to complete tests comfortably even with their eyes closed [6]. Group 3: Technical Advantages - The ultra-thin flexible OLED integrated into the contact lens is only about 12.5 micrometers thick and includes a wireless power receiving antenna and control chip, enabling independent operation [6]. - The OLED technology, being a surface light source, can induce retinal responses even under low brightness conditions, achieving stable ERG signals at only 126 nits, comparable to existing commercial light sources [6]. - Animal experiments confirmed that rabbits wearing the OLED contact lenses maintained a surface eye temperature below 27°C, preventing corneal thermal damage [6]. Group 4: User Convenience - The new contact lenses utilize a wireless power transmission method at a frequency of 433 MHz, and the team has embedded a wireless controller into a sleep mask connected to a smartphone, enhancing user convenience [8].
