A new type of contact lens has been developed that allows users to see in the dark by enhancing visibility of infrared light.
In a study published in the journal Cell, neuroscientists detailed how these lenses convert infrared light into something visible.
The intriguing part? The wearer doesn’t need any power source. They are able to perceive both standard visible light and infrared rays simultaneously, with visibility improving notably when their eyes are shut.
“Our research opens up the possibility that non-invasive wearable devices can provide enhanced vision,” noted Tian Xue, who is a senior author and neuroscientist at the University of China Science. It’s fascinating, really.
The lenses are created by combining nanoparticles with a safe, flexible polymer typically used in soft contact lenses.
“It’s remarkable. Without these contact lenses, individuals can’t see anything, but once they wear them, the flickering of infrared light becomes clear,” Xue explained.
At this stage, the lenses can detect infrared radiation produced by LED lights, but there’s hope that they’ll eventually capture lower levels, too.
“Looking ahead, we aspire to collaborate with materials scientists and optical specialists to develop lenses with improved spatial resolution and sensitivity,” Xue added, hinting at exciting possibilities.
