Annie Dillard said this quote

“ I chanced on a wonderful book by Marius von Senden, called Space and Sight. . . . For the newly sighted, vision is pure sensation unencumbered by meaning: The girl went through the experience that we all go through and forget, the moment we are born. She saw, but it did not mean anything but a lot of different kinds of brightness. . . . In general the newly sighted see the world as a dazzle of color-patches. They are pleased by the sensation of color, and learn quickly to name the colors, but the rest of seeing is tormentingly difficult. . . . The mental effort involved . . . proves overwhelming for many patients. It oppresses them to realize, if they ever do at all, the tremendous size of the world, which they had previously conceived of as something touchingly manageable. . . . A disheartening number of them refuse to use their new vision, continuing to go over objects with their tongues, and lapsing into apathy and despair. . . . On the other hand, many newly sighted people speak well of the world, and teach us how dull is our own vision. ”
