Gene Editing helps blind mice see

When a team of scientists delivered the gene for a retinal opsin into the genome of the ganglion cells of blind mice, the mice acquired vision that lasted a lifetime. “That this system works is really, really satisfying, in part because it’s also very simple,” noted Ehud Isacoff, PhD, professor of neurobiology at the University of California (UC), Berkeley, and lead author on the paper. “Ironically, you could have done this 20 years ago.”
