We have the technology to not only rebuld him but to build him better.

There's been advances in restoring and/or bettering sight for a few years now. I've even posted it about it here in this blog before but this is something not only brand new but makes sight better.

We have have seen the procedure of the Argus Retinal Prosthesis which hard wires the brain to an outside input device (i.e. small camera) where that device acts as your new eyes and provides images directly into the brain. Well "Cybersight 2.0" is here. The new version called the Argus II Retinal Prosthesis takes the first gen system, which has a resolution of 16 pixels, pushes the resolution to 60 pixels. There's no definite answer to what this 4x resolution will allow the patient to see but its not far fetched to think that they'll be able to see details in difference between or loved one's faces or whether they're grabbing a steak or salad fork at the table.
At this pace its not far fetched to think we'll have the full-on Steve Austin (of "6 Million Dollar Man" fame not the WWE wrestler or even dare I say it Geordi Laforge) bionic eye very soon. To hell with just seeing, lets zoom in and switch to "thermal".
