www2.technologyreview.com— An advance in triggering individual retinal cells could one day lead to implanted artificial retinas for treating blindness.

The world's most dangerous idea apparently is apparently one of the least known as well. Transhumanism promises a lot more than fixing what's broken. Wouldn't it be nice to have no blind spots? Or to have zoom on demand?
That the retina is arranged upside down really has nothing to do with the fact that a point on the retina still needs to connect it to the visual cortex. As for artificial eyes tapping into the optic nerve, we still don't have any concrete understanding of the subtle nature of the electrical signal the optic nerve transmits -- all this retinal implant does it attempt to replicate or trigger the firing off of the cells in the retina, how the optic nerve and the visual cortext interprets this is still along way from being fully understood.But blind spots should be one of the last things we're worried about, our eyes were specifically designed to overcome the blind spot, hence our ability to "look around."
ocular implants, anyone?I'm holding out for the X-Ray/Thermal/Scanning/Combat visor abilities like Samus. That, would be amazing. (not that this isn't already)

not only did those steroids shrink bonds' testicles, but they also diminished his sight of seeing.
