Experimental retina implants give mice infrared vision
Human vision relies on photoreceptor cells in the retina that react to visible light and trigger neurons in the optic nerve to send signals to the brain. Degradation of these photoreceptors is the leading cause of vision impairments, including blindness. However, a team of scientists at China’s Fudan University has recently built prototype retinal implants that can replace the failing photoreceptors and potentially provide infrared vision as a bonus. Sadly, they’ve only been tested in animals,
