Van Gogh began his work relying on the Dutch Masters. He was intrigued with the Masters' power to play with shadow and lightweight. He also found a connection within the painting of common events and/or people. For instance, The Potato Eaters captures several peasants sitting yourself down for a meal. The painting is dark, yet, light radiates in the faces. Amazingly, there isn't a lots of scientific research about how glasses can transform the way in which people see you -- instead of how they see what's facing them. But there's a high correlation with the Hollywood notion the fastest way to turn actors into giving the impression of scientists is always to make them wear a pair of not too flattering spectacles.
