Bionic eyes are sometimes used to help the visually impaired. The diagram illustrates how the process works. Initially, the patient receives an implant in their retina. Glasses worn have miniature cameras in the lens, which then send signals to the implanted chip located in the retina. Then, the chip converts these signals into electrical impulses that can then be sent to the optic nerve and processed as an image. The brain of the visually impaired has the ability to rewire in order to efficiently use the parts that are typically used for vision, as their other senses become keener in order to compensate- sound, for example, can activate the visual cortex of a blind person’s brain.
