Lying blind: hiding vision loss in plain sight

James Tate Hill lost nearly all his sight as a teenager to a rare condition called Leber's hereditary optic neuropathy. By the time he was 16, he was legally blind. But he could still pass for sighted, so that's exactly what he did, walking without a cane and turning up to meetings early so that no one would see him make his arrival. His new memoir, Blind Man's Bluff examines the lengths he went to while pretending to see, and why he eventually decided to quit the charade.
