Barbara's Blindness -- Film Description:
"The main source of the film [Barbara's Blindness] seems to be an old grade-school morality-movie on the appreciation of eyesight, starring golden-haired Mary, who finds herself temporarily blind, and a leaden-voiced narrator, who finds himself our unwitting straight-man. The filmmakers [Joyce Wieland and Betty Ferguson] re-edited this curiosity and intercut it with other stock footage of disasters, agricultural techniques, and monster movies, to create a very different object lesson on the nature of vision."
