Dwight suffers from partial vision loss - he has holes in his visual field. He recognizes people mainly by voice, but he's able to see well enough to track boats on the river.

Dwight is something of a living history of the Institute. He recounts “sitting in Lobby 7, watching the TV during Watergate in the summer of '74.” He was also on the first Orange Tours, when “this guy on Third East decided, 'we'll lead a different tour of the Institute, late at night.'”
