TV segment features device designed to restore some vision to the blind

NBC Nightly News reported that a new device offers the enormous promise of restoring sight for those who don't have it. Chief science correspondent Robert Bazell interviewed Kathleen Blake, once totally blind, but now able to see, thanks to a tiny TV camera mounted on her sun glasses that sends images to electrodes placed on the back of her eye.

For 20 years, Dr. Mark Humayun and his team at the University of Southern California (USC) have been working toward the amazing goal of restoring vision to the blind. Not long ago, the USC researchers achieved great improvement in the device, going from 16 electrodes to 60, enabling better sight. According to Bazell, Soon, the glasses will go. Armand Tanguay, an electrical engineer, is developing cameras to be implanted directly in the eye lens in a system many scientists believe will restore better and better sight to millions.
