FASTER, PLEASE: Retina Implant Restores Vision, Lets Cyborgs See IR Spectrum! “Scientists in Germany have developed a retina implant to restore vision to the blind that hints at the augmentation cyborgs may receive in the future. The device, developed by Retina Implant AG, is an array of 1500+ photodiodes (roughly 38×40 pixels) that is surgically placed under the retina. Light that enters the eye stimulates the photodiodes which send electric currents through the underlying neurons. In a recent article in the Proceedings of the Royal Society B, researchers describe how blind patients (mostly suffering from retinitis pigmentosa) were able to see light and dark areas and discern basic shapes only a week after their surgeries. One man was even able to see the difference between objects, and read large letters! That would be remarkable enough, but implanted patients also reported a sensitivity to infrared light. That?s right, the retina implant could only provide very basic vision, but it did so in an extended spectrum. Cybernetic implants like these may not only be able to restore sight to the blind, they could let them see things that no normal person has ever seen before with their own eyes.”
