Bionic eyes

This is cooler than Google glasses! These glasses help with people who are nearly blind, but not completely blind. I wonder if they could redo the design, like hook up the gear to more common designed glasses. Not like it really matters...

I wonder, since companies like Google and Apple wanted to revolutionize things and make the best products for consumers, why they didn't go into tracks like this? I bet they could have come with some really crazy helpful stuff for people with disabilities. I'm not well versed on their endeavors, so maybe they have tried and I'm unaware. It also a different field from pure tech, but maybe they can pair up with scientists. That'd be cool.
