In a review of the Color Uncovered iPad app, Carl Zimmer highlights something I hadn't heard before: Claude Monet could see in ultraviolet.
Late in his life, Claude Monet developed cataracts. As his lenses degraded, they blocked parts of the visible spectrum, and the colors he perceived grew muddy. Monet's cataracts left him struggling to paint; he complained to friends that he felt as if he saw everything in a fog. After years of failed treatments, he agreed at age 82 to have the lens of his left eye completely removed. Light could now stream through the opening unimpeded. Monet could now see familiar colors again. And he could also see colors he had never seen before. Monet began to see -- and to paint -- in ultraviolet.
The condition is called aphakia.
