In place of a lost eyestalk, the Gran pirate known as Pax used an eye patch.
A clothing item known as an eye patch could be worn to cover a missing eye or eyestalk. Captain Typho, a human, famously wore a silver eye patch over the location where his eye used to be during both the Fall of the Jedi and the Reign of the Empire. Similarly, during the New Republic era, the Gran pirate named Pax utilized an eye patch, complete with a band, to cover the area where his rightmost eyestalk was absent.
