Hi and welcome :) I suppose there is a bit of a theme going on, with the eyes and the perception filters and stuff; but I just wish there was a less generic term.

Douglas Adams would have loved perception filters, he being the inventor of the SEP field (Somebody Else's Problem), that basically does the same thing. I think the SEP field was how the Immortal creature who decided to go about insulting every known creature in the universe (in alphabetical order) landed his spaceship on a football pitch with no one noticing? I may be glomming together a few things there... ;)
