Good day, gentlemen.
Tell us what artificial vision systems are known at the moment, what technologies they use, what capabilities of the human body are they based on?
Are there systems ready for practical use at the moment? Are there systems that can help with optic nerve dysfunction?

Answer 1

I won't give a link, but the last time I heard about a resolution of 16 (4x4) pixels in this area. those. there is a camera on the glasses, a receiver is connected to the nerve and receives a picture from the camera by radio, the power was also wireless. It seems that there is nothing better yet, but people are working in this area.
