Despite some mistaken characterizations over the years, Popeye is generally depicted as having only one blue eye, his left. In at least one Fleischer cartoon, Bluto refers to Popeye as a “one-eyed runt.” It has never been revealed specifically how Popeye lost his right eye, although he claims it was in “the mos’ arful battle” of his life. Later versions of the character had both eyes, with one of them merely being squinty, or “squinky” as he put it.
