The trivia in Boruto Uzumaki's Dōjutsu says that the atuhor "noted that all this information would be explained in detail in the future and fans should not think too much of it for now".

More info will be given in time. There's still a possibility that the eye's "name" will be changed or something. It's somewhat odd of an animator to reveal something on their own, also note the pun in the name and the drawing.
