How do bionic eyes work?
All bionic eye devices function in the following manner: A camera attached to a pair of glasses captures the image and transmits the data to a processing unit which is worn on the body. The data is processed and sent to the implanted system either wirelessly or through an external wire. An implant situated behind the ear receives the signals from the processing unit and sends them to the electrode array via a wire. These pulses are intended to stimulate the retina’s remaining cells, resulting in a corresponding perception of patterns of light in the brain. Following the implant, patients learn to interpret these visual patterns, allowing them to detect shapes of people and objects in their surroundings. Plasticity of the brain plays an important role in enabling the outcomes of the devices.
