I cannot speak for the film, as I have not seen it (and will not! see it) but, as for the book it's from, let me quote..
"The shouting had died down, now a confusion of sounds was coming from the hallway, these were the blind, driven like sheep, bumping into each other, crammed together in the doorways, some lost their sense of direction and ended up in other wards, but the majority, stumbling along, huddled into groups or dispersed one by one, desperately waving their hands in the air like people drowning, burst into the ward in a whirlwind, as if being pushed from the outside by a bulldozer."
"Then the inexorable rise in the number of cases of blindness led some influential members of the Government, fearful that the official initiative would not suffice for the task in hand, and that it might result in heavy political costs, to defend the idea that it was up to families to keep their blind indoors, never allowing them to go out on the street, so as not to worsen the already difficult traffic situation or to offend the sensibility of persons who still had their eyesight and who, indifferent to more or less reassuring opinions, believed that the white disease was spreading by visual contact, like the evil eye."
"No one's nerves could withstand it. The worst thing is that whole families, especially the smaller ones, rapidly became families of blind people, leaving no one who could guide and look after them, nor protect sighted neighbours from them, and it was clear that these blind people, however caring a father, mother or child they might be, could not take care of each other, otherwise they would meet the same fate as the blind people in the painting, walking together, falling together and dying together."
This is NOT how a civilized society sees blindness. This is not an acceptable portrayal of disability in a civilized world. This takes us three thousand steps back.
