In 2002 researchers in Austraila announced the creation of a bionic eye. That model required the user to wear a pair of spectacles with a camera that would transmit signals to a retinal implant that was made up of an array of 16 eletrodes. The results were as expected with those trials. The image resolution was 10×10, and allowed the user to know if their surroundings were dark or light, and detect some movement.
2003 saw 3 people in the US fitted with a bionic eye.
Now the newer model is fit to be tested. It is the same basic device, but instead of the handful of electrodes that allow 10×10, the upgrade has 50 to 100 electrode sensors. It still won’t provide normal vision, but as said by Professor Dagnelie:
“To us, the images look very basic but for someone who was previously blind they are a massive step forward.”
