US research and development of electronic contact lenses

At an international conference organized by the Institute of Electrical and Electronics Engineers (IEEE), Ho announced that his team had successfully embedded a circuit and a light source into standard contact lenses for the first time. The circuit used in the lenses was made from ultra-thin metal layers, measuring just a few nanometers in thickness—where one nanometer equals one billionth of a meter. During testing, rabbits wore the experimental lenses for over 20 minutes without any adverse effects on their eyes, indicating the technology's potential for human use.

Barbak Parviz, an electrical engineering researcher at the University of Washington who collaborated on the project, highlighted the promising future of this innovation. He noted that while the initial results were encouraging, the technology could have a wide range of applications. For instance, divers and pilots might use these lenses to monitor direction and speed in real-time, while gamers could experience immersive gameplay directly through their vision. Additionally, individuals with visual impairments might benefit from enhanced vision or even restored sight in the future.

Parviz emphasized that the goal of the research was not only to demonstrate the feasibility of the technology but also to ensure its safety and effectiveness. “People may discover applications we haven’t even imagined yet,” he said. “Our focus is on proving the basic concept and making sure it’s reliable and safe for long-term use.”

This development marked a major step forward in wearable technology, blending medical science with cutting-edge engineering to create devices that could change how people interact with the world around them.
