Bill leaves the hospital to learn that everyone in the area - perhaps everyone in the world - has gone blind. He, and anyone else who didn't see the comet the previous night, are the exceptions. Meanwhile, the triffids are attacking.
Bill leaves hospital to find the city deserted and devoid of all amenities. He comes across a family whose little girl is still sighted and who want him to stay and help them but he presses on through streets filled with blind looters in search of other sighted survivors. He rescues Jo,who slept through the meteor shower and is being used by a blind man as his guide, and they go to her house,only to find that her father and house-keeper have been stung to death by the now ambulant and deadlier triffids. On their way to find guns they are attacked by an angry mob of blind people.—don @ minifie-1
