Restoring Vision in Blind Mice

Scientists have discovered a technique that apparently restores a significant degree of vision in mice that were blind. 

It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems. They were able to see motion, brightness changes over a thousandfold range and fine detail on an iPad sufficient to distinguish letters.

Being very nearsighted, I'm quite aware of the possibility of developing macular degeneration or other serious eye problems. This gives me some hope that there will be a cure, or at least a mitigation, within the next few years.
