For over a decade, companies around the world have attempted to create smart contact lenses, but they never got down to incorporating electronic components to make a safe battery. LEE SEOK WOO: So, when I decided to work on contact lenses and the power supply to the smart contact lens, I was concerned about the safety because the lithium-ion battery has the issue of the explosion or catching fire. Unlike traditional contact lenses, smart contacts have the potential to do more than just correcting the users' eyesight. So, it might be hard to implant all the devices into one smart contact lens. And of course, the technology needs to be patented first before these smart contact lenses become a reality.
