Revolutionary Lenses Allow Humans to See in the Dark Without Opening Eyes A Breakthrough in Noninvasive Vision Enhancement A team of neuroscientists and materials scientists has developed contact lenses that grant infrared sight in humans and mice by transmuting infrared into visible light. Unlike traditional night-vision googles, these lenses — reported in Cell — need no external power and allow perception of several infrared bands. Their transparency permits simultaneous viewing of infrared and visible light, with superior IR vision when the eyes are closed. "Our findings pave the way for wearable, noninvasive technologies that could grant humans enhanced vision," remarks Tian Xue, lead researchers and neuroscientist at the University of Science and Technology of China. "The material offers immediate possibilities —flickering infrared light, for instance, may serve to relay data in contexts such as security, rescue operations, encryption or anti-counterfeiting." ...
