*Black Eyed Peas member Apl.de.ap suffers from a rare genetic eye disorder that has rendered him legally blind.

This rapper, real name Allan Pineda Lindo, has revealed he has constant blurry vision and severe nearsightedness as a result of nystagmus, which makes his eyeballs vibrate involuntarily. His vision is so poor that even with optimal contact lenses, he is legally blind, reports People magazine.

“I’m good at shapes. If I’m not close, even if it’s big, I can’t read it,” said Apl, who is also colorblind.

Apl admits secretly suffering from the condition as a child sparked his interest in hip-hop.

He adds, “Until I discovered hip-hop, I felt I wasn’t going to accomplish anything. When I dance, I picture myself and the floor in my head…I doubted myself for a long time… I’m comfortable not using my vision. I weave around my problems.”
