nah we're getting closer. The problem has always been power, that tiny of a display isn't anything even remotely difficult. There'd have to be a wireless power supply somewhere on you to keep that shit alive, most biohacker groups speculate solar panels on hats or just clipped to a shoulder or something, wired to a wireless battery that feeds to the eyepiece.
Also the contact lens is a misnomer, it'd probably have to be glass, slightly thicker than glass really, due to the display inside of it.
Beyond THAT, the issue lies in controlling it. There's probably a way you could use pressure, like long blinks, but that's not intuitive for most people, and certainly not ideal.
t. someone who has a cybernetic eye, basically a camera with a battery pack glued onto the back of it stuck in my eyesocket.
