    This is good news for my roommate, he is blind with this condition. He's totally blind so as it is now wouldn't help him, but in the future this could restore his vision. Let's hope they can improve the product.

    If this is the same technology I've heard about previously, then it can be used to restore sight to someone completely blind.

    Each point on the implanted grid acts as a rod, and sends the information down the optic nerve which is interpreted by the brain as one giant point of light. It's still rather limited at the moment. The image produced by the technology is only able to resolve an image within a 16x16 grid, where each point acts somewhat like a pixel on a monitor.

    If you want an example, the documentary I saw had one of the recipients trying to identify an object on a table. A banana in this instance. What he saw looked something like this...

    So no, it isn't anywhere near a crystal clear image at the moment. But I'd imagine it's still far, far preferable to the alternative.

    Oh I agree that right now it wouldn't restore sight to someone that is totally blind like my roommate. But in the future with tech getting better every year it might not take as long as you think. This procedure is only 6 years old (although some procedures like this one have been being development for years) and they are this far with it, just think what another 6 years could hold.

    It can restore sight to those who are completely blind. The limitation is if the person was born completely blind.
