Book excerpt: This title presents a celebration of vision, of art and of the relationship between the two. Artists see the world in physical terms as we all do. However, they may be more perceptive than most in interpreting the complexity of how and what they see. In this fascinating juxtaposition of science and art history, ophthalmologists Michael Marmor and James G. Ravin examine the role of vision and eye disease in art. They focus on the eye, where the process of vision originates and investigate how aspects of vision have inspired - and confounded - many of the world's most famous artists. Why do Georges Seurat's paintings appear to shimmer? How come the eyes in certain portraits seem to follow you around the room? Are the broad brushstrokes in Monet's Water Lilies due to cataracts? Could van Gogh's magnificent yellows be a result of drugs? How does eye disease affect the artistic process? Or does it at all? "The Artist's Eyes" considers these questions and more. It is a testament to the triumph of artistic talent over human vulnerability and a tribute to the paintings that define eras, the artists who made them and the eyes through which all of us experience art.
