It's True!

After studying 36 self-portraits of the great Dutch painter and etcher Rembrandt, two students of the Harvard Medical School published a paper in 2004 suggesting that the painter's eyes failed to align correctly, and he consequently suffered from stereo blindness. This disability could have helped him to flatten images he saw, and then put it onto the two-dimensional canvas. One of the students theorised that this was an advantage for the painter.
