Contact lens case changes color to signal bacterial contamination
SAN DIEGO — Researchers have developed a microbial sensing device that alerts contact lens wearers of unsafe levels of bacteria and to discard the lens. They presented their findings at ICAAC 2015.“We have devised a real-time sensing device, embedded within a contact lens case, that is capable of signaling the presence of abnormal levels of live microorganisms,” Nishal Govindji-Bhatt, PhD, a postdoctoral research associate at the University of Manchester, said in a press release.
