Both larval and adult barnacles have a single eye - although it's probably more of a "light sensor" than what we think of as an "eye" since it pretty much is only capable of sensing the difference between light and dark/shadow. In the nauplius (larva) it's a spot on top of the the barnacle on the end that would be considered the head. In the adult, the eye is developed/derived from the naupliar eye. Since barnacles attach themselves by their heads (kinda by their forheads) to the surface they are stuck to, the vestigial eye/light-sensor would be on the side, down near where the barnacle has attached itsself to a surface.
