Through the unfortunate circumstance of becoming encompassed in the white blindness, all of the characters got to chance to see the world and themselves in an entirely different light which is an experience that would be so beneficial to re-create and extend to the real world.
Another way in which I think our society as a whole is blind, is in the way in which we perceive and treat people with physical or mental impairments. Instead of looking at those who are disabled as our equals, we feel sorry for them and in some instances are nice to them because we feel guilty. Although the doctor's wife was the only person in the story to not go blind, she was by far not the luckiest. She had to see and experience things that the rest of the group was lucky to have been blind too. Although the others were aware of the immense suffering going on around them, they didn't even know the extent of it like she did. She saw people searching for food tattered, dirty, and almost hopeless. On her excursions, she encountered the terrible condition of the town, she saw people's defecations scattered about, and she witnessed death like no one else truly could. Because a blind person cannot physically see the world, it can be whatever they want it to be. People and places can be beautiful. Although all seven people within the group felt the immense suffering and pain of the blindness, the doctor's wife had the extra burden of not only feeling it within her heart and mind but being an eyewitness to the horrible events. On some level, maybe blind people are lucky because they can see the world as beautiful even at moments when it isn't.
People that are fortunate to have everything they need seem to forget the reality of how lucky they are. Especially growing up in the United States, which is such a prosperous and rich country we forget how privileged we are just to have food on the table. We are blind to the fact that not everyone is that lucky and until we lose it we forget that having enough to eat is a luxury that not everyone enjoys.
