Now, scientists in the United Kingdom are trying to address the needs of the legally blind with a pair of “smart” glasses. ![]() They may have decent peripheral vision but no sight in the center, or they may have only central sight, or “tunnel vision.” They may be able to see light or large objects that are very close.
