I'm trying to research and write about visual prostheses/bionic eyes.

 

Do we know what's the current best model on the market?

 

Is there a version with an electrode array of 100+ or even 1,000+ electrodes?

 

With enough info, it should be possible to extrapolate a trend, and figure out roughly when bionic eyes will match human vision.

 

The human eye has a resolution equivalent to around 576 megapixels (MP). That's obviously far beyond the capability of today's cameras, but perhaps with exponential growth it could be achieved in the not-too-distant future.

 

Any info and suggestions would be appreciated. :)

We all know about the Argus II but have you heard of Pixium Vision? I'm not sure if it's strictly a bionic eye but I'll let you judge that.

Very interesting, thanks. I hadn't heard of it.

 

Basically I'm deleting the bionic eye entry for 2019, as the company has been acquired and little seems to have happened since then, but I really want to add this prediction back at some point. So I will keep hunting for info and see what I can find.

On the topic of gigapixel cameras: I mean, obviously not for commercial sale. But I know there are a few ultra-high tech cameras out there, such as one that has 1.5 gigapixels

And remember my friend, future events such as these will affect you in the future.

Returning to this topic, I found a graph today while Googling various stuff.

 

It's not much – but it provides the starting point for a graph.

 

The data originates from a 2012 report, so I'm not sure how accurate the trend is after that year.

 

If any of you guys could post additional bionic eyes and their resolutions by year (especially post-2012), that would be massively helpful to me.

Here's the latest news on the Prima System by Pixium Vision which I referred to above. It's dated July 29, 2019. 

 

According to the article, the system uses a 2mm diameter photvoltaic chip implanted under the retina. It has 378 electrodes which is clearly behind the projection curve shown in the graph above. 

 

Interesting aspect of this implant is that it is powered by a beam of infrared light from a miniature projector on the glasses the person is wearing.

After more Googling, I found this useful list of retinal prosthetic devices.

The dates aren't entirely clear though, so I'm researching those.

 

Also, the current highest pixelation appears to be this device from Iridium Medical Technologies (4000 pixels).
