Actor Johnny Depp has recently revealed that he is blind in his left eye. Depp has been struggling with his vision all his life. He is near-sighted in his right eye and has never had proper vision.
He wears glasses when not on set, because without them he can only see a few feet in front of him.
Being one of Hollywood's most versatile actors, one would never notice that he is battling to see while he is portraying his deep, dark, or sinister characters.
