Optical Theory
A letter published in 2004 by Margaret S. Livingstone, professor of neurobiology at Harvard Medical School, suggests that Rembrandt, whose eyes failed to align correctly, suffered from stereo blindness. This conclusion was made after studying 36 of Rembrandt's self-portraits. Because he could not form a normal binocular vision, his brain automatically switched to one eye for many visual tasks. This disability could have helped him to flatten images he saw, and then put it onto the two-dimensional canvas. Livingstone theorized that this was an advantage for the painter: "Art teachers often instruct students to close one eye in order to flatten what they see. Therefore, stereo blindness might not be a handicap—and might even be an asset—for some artists."

Famous quotes containing the words optical and/or theory:
“People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations.”
—Alexander Herzen (1812–1870)
“We commonly say that the rich man can speak the truth, can afford honesty, can afford independence of opinion and action;—and that is the theory of nobility. But it is the rich man in a true sense, that is to say, not the man of large income and large expenditure, but solely the man whose outlay is less than his income and is steadily kept so.”
—Ralph Waldo Emerson (1803–1882)
