Bionic eyes that are as good as (or better than) human eyes
For the 40 to 45 million people around the globe who are blind, bionic eyes could potentially restore sight. Bionic eyes are linked to the visual cortex, the part of the brain that takes in visual information from our eyes and creates the images that we recognize as sight. This happens so quickly that we are not even aware of it. Technology is not quite advanced enough to perfectly reproduce the seamless communication between the eye and brain but it might in the near future. Eye implants that allow patients to visualize shapes and colors and a brain microchip that creates artificial vision using a small camera already exist.
