A driver waiting at the traffic lights goes blind. An opthamologist tries to diagnose his distinctive white blindness, but is affected before he can read the textbooks. It becomes a contagion, spreading throughout the city. Trying to stem the epidemic, the authorities herd the afflicted into a mental asylum where the wards are terrorised by blind thugs.
José Saramago, Blindness
“I don't think we did go blind, I think we are blind, Blind but seeing, Blind people who can see, but do not see.”
