Blindness

Blind 

Reading the beginning of this book made me think about a movie that I recently watched called bird box. This move is very similar to what’s happening in the book. Where in order to survive in thre movie people had to have their eyes covered. If they decided to look the spirit or whatever it was that was in the air made them want to kill themselves or kill someone else if they praise It . In the beginning of this novel I found it so strange that few characters ended up blind first the man who was driving and then the one who tried to be a good samataerian like the book say  why driving the blind man , the eye doctor also end up blind , what is it that they end up blind ? What is going on this is making me wonder is there a disease ? Or maybe is their something in the air that is affecting them.  By being isolated by the government, is everyone else safe or will they eventually be affected?
