HELP. movie about creature that can olny be seen with glasses

can someone help me find the movie i’m looking for? I don’t remember the name of the movie, but I do remember a few scenes. like there is a monster that can only be seen with glasses, and if I’m not mistaken the monster’s blood is green. then the ending of this film is that the father of the main character descends from the sky with many fairy-like creatures

Possibly They Live, with Roddy Piper, he can only see the aliens through special glasses…

The Love war with Lloyd Bridges.

The aliens appear green through the glasses, as can be seen around the 1:09:00 mark: The Love War TV 1970 - YouTube
