KH3D Secret eye on keyblades ?!?!?

[xXRikuXx 0]

I've noticed that everyone who has some kind of relationship with relationship with xehanort has an eye on his keyblade for example xehanort's keyblade has an eye on the top of it vanitas's keyblade had two eyes one on top and one above the handle. Also both riku's keyblades ,soul eater and way to dawn, have an eye above the handle just like vanitas's keyblade. Does this may mean something?

It means that Xehanort is always watching you?

It means that a disembodied eyeball is creepy. It means Square was searching desperatly for a way to make a pink bat wing look intimidating.
