The way Nassetti envisions it, users could choose between three different types of synthetic EYEs: Heal, Enhance, and Advance. The first is a synthetic eye that basically works just like a natural one and could serve as a replacement for people with diseases or traumas that would otherwise be blind. EYE Enhance seeks to improve the eye’s natural functions by improving vision to 15/20 and enabling filters on vision like those on photo apps (such as vintage, black and white). To turn on or change the filter, a user can take a pill. The third type, Advance, has additional glands to capture or record what a person is seeing, as well as a Wi-Fi connection to share those images.
