Main Entry: goggle-eyed
Function: adjective
Etymology: Middle English gogeleyed, from gogelen + eyed

Fuer mich ist "Glubschauge" umgangsprachlich, auch wenn der Duden das Wort nicht so markiert. Schriftsprachlich wuerde ich eher "hervortretende Augen" = "bulging eyes" / "protruding eyes" verwenden.
