If you squint

…your painting might be more convincing. Stereo blindness, or lack of depth perception, may actually be an advantage when it comes to art.

Looking at the world through one eye at a time automatically “flattens the scene,” said Margaret S. Livingstone, an expert on vision and the brain at Harvard Medical School who helped carry out a study on stereo vision.

That appears to give people with stereo blindness a natural advantage in translating the richly three-dimensional world onto a flat two-dimensional canvas, she said. They use monocular depth cues like motion, relative size, shadows and overlapping figures to stimulate a 3-D world.

And if you’re historically-inclined, the best part? Livingstone first noticed the relationship between stereo blindness and artistic ability while studying eye deviation in self-portraits of Rembrandt.
