Essay on Blindness is a literary text that tells the story of a new pandemic - the blinding white - through of many groups of people that for them is infected. When the disease manifests in a humans and spreads to all those with whom he contacted in a short space of time, the government decided to isolate patients in a lunatic asylum out of use, but soon it appears that the power of contagion overcomes all preventive measures can make. It is through the eyes of the only person immune to blindness, the wife of an ophthalmologist, we see the scenario of decline, both physical and psychological, where the history of the inhabitants of the hospital takes place. In the lunatic asylum, the food rarefy, thanks to a poor supply carried out by soldiers and terrified the increasing overcrowding of the site. The cleanliness becomes impossible, and the precarious conditions of life emerging attitudes of great violence and selfishness. When the blindness reaches gigantic proportions in the world outside the lunatic asylum, the wife of ophthalmologist leads her small group of blind people out of the hospital, through a city that don’t know, populated of dirty and a save-the-who-can overall, in search of supplies that seem to have disappeared with the vision. After going through the houses of fellow survivors in search of relatives to blindness, the wife of ophthalmologist leads the group to her home, where they spend the days and nights soothing the hope of a cure to seem increasingly distant. It is one of those nights that the first blind launches a cry of joy and announced to his companions who recovered the vision. One by one, and the same order they were infected, the blind see again.
