The British neurologist and author Oliver Sacks recently chronicled the experience of losing his sight from ocular melanoma in a series of journals and an interview with Wired magazine.
It’s the sign of a rigorous scientist to empiricize personal deterioration and apparently Sack’s experience revealed some interesting tidbits. He saw chessboards and question marks float in and out of his field of vision in his right eye. This allowed him a geater level of empathy when interacting with his visually-impaired patients. Sacks, who now has no central vision, also landed a gig on Ted Talks, to be posted shortly, where he further revealed the secrets of sight and sightlessness.
