Photovoltaic Eye Implant Could Give Sight To the Blind
MikeChino writes with this snippet from Inhabitat: "Researchers at Stanford University recently announced that they have developed a new artificial retina implant that uses photovoltaic power and could help the blind see. The problem with previous implants was that there was no way send power to the chip in order to process light and data inside the eye, so the new device uses miniature photovoltaic cells to provide power the chip as well as to transmit data through the eye to the brain. The new device has great promise to help people afflicted by the loss of photoreceptor cells by using the power of the sun."
This sounds really awesome. If my natural vision degenerates, I want the model with IR and UV sensitivity.
But I can see an endless loop condition developing:
10: "Don't look into the sun, you'll go blind!"
20: "AAAA I looked into the sun and I'm blind!"
30: "We've given you solar-powered retinal implants."
40: "Oops, my eye batteries are low, I'd better go..."
50: goto 20
Stressed? Me? Of course not. Stress is what a rubber band feels before it breaks, silly.
unless maybe they put a storage battery in their nose?
But does it use Glitter?
Gives the old, often used adage of "glittering eyes" an entirely new dimension. Plus, think of what a hit it'd be at parties :)

It's old. The more humans I meet, the more I like my cats. At least they are honest.
The only real drawback might be some engineers staring into the sun and going blind on purpose for all that La-Forge microscopic infrared and other wavelength advantage.
I mean, Chief Tyrol just used a infra-red beam and it showed up Galactica's problems real well, but this is the real world right?

but now how do you see in the dark?

Hopefully this mini-cam will have a little better light pickup than most of the cameras out there. I can see this being a big problem with someone fumbling about the house that doesn't have alot of bright lighting. Just take a look at a few indoor youtube videos to see what I mean.
Eh? A Chip? Why does it need a chip? The eye certainly doesn't have any processors of any sort in there.
It has a detector and some wiring in to the brain.
And i don't even have IR and UV sight with said chip?? Come on guys.
Why can't it just be wired up to use the power already in our body?
There was that e-ink tattoo that can be powered from human blood.
If the eyelid is shut, lower the amount of power being used.
One place where this is going to fail badly is low-light.
They could put a battery in there, but i wouldn't be all excited about having a battery in my eye either when you consider leakage, explosions and such.
Yeah, its not so much of a problem considering that they actually HAVE sight now, but coming from a "nocturnal" person, i'd hate this.

wrong. the retina does a lot of quite useful processing on the image before sending quite high-level data to the brain: http://en.wikipedia.org/wiki/Retina#Spatial_Encoding
there are lots of hard-to-explain cases where somebody can see perfectly; but can't detect movement, or where can't recognize the border between shapes, and therefore is unable to make sense of what sees, etc.

I know it's just ranting but I'd like to let people know that there are processors in the eye. The message sent to the brain is not just a bmp representation of the image on the retina. Wikipedia probably knows more.
