Black Eyed Peas rapper apl.de.ap has revealed that he suffers from genetic eye disorder Nystagmus, which makes him legally blind.
As opposed to ILLEGALLY BLIND.
"When I dance, I picture myself and the floor in my head," he told The Sun. "I'm comfortable not using my vision. I weave around my problems."
Nystagmus gives him perpetually blurry vision, involuntary eyeball vibration, and nearsightedness. "I'm good at shapes," he explained. "If it's not close, even if it's big, I can't read it."
