Given that many women may be carrying the mutation, why do so few people prove to have such astonishing vision, for instance? “One possibility is that you need early training to capitalise on the signal,” says Kimberly Jameson at the University of California, Irvine, who has tested Antico extensively. Antico is an artist, who has paid close attention to subtle variations in colour for almost all of her life. “I was fairly manic,” Antico says today. “I always wanted to represent everything I could see.” Perhaps this kind of intense experience was crucial to rewire the brain so it could cash in the extra signals her eyes were receiving....IN THE COMMENTS: Ignorance is Bliss said...
Somebody calls you, you answer quite slowly...ADDED: The subject of whether an artist with abnormal eyes can make a painting that lets ordinary people see what the artist sees came up in the context of El Greco in this well-reasoned letter to the NYT which I read 25 years ago and never forgot:
''Studying Art With the Eye of a Physician'' discusses the debunking of the theory that El Greco painted elongated figures because of astigmatism, a disorder in which the eyeball is more elongated than round. The proof that astigmatism did not cause El Greco to draw elongated figures is relatively simple:
If he chose to draw a life-size man six feet tall, the man and his drawn image side by side would be the same length with or without astigmatism. An astigmatic person would perceive the length of the man and his life-size image as equivalent. Any perceived distortion in length would apply to both the object and the drawn image.
I have noticed also that El Greco's elongation applied to vertical torsos, not to horizontal ones. If he were consistent, the hips of a reclining, horizontal figure would be 15 percent to 25 percent wider in the vertical direction. But I have not seen this in his paintings.
