To justify my reasoning, I'm thinking specifically of Supernormal Step. The author, Michael Lee Lunsford, has something of a Fingerless Gloves fetish - almost everyone in Supernormal wears them. Typically, fingerless gloves are a perfect example of Goggles Do Nothing. The gloves are almost always worn for simple Rule Of Cool. However, Lunsford chose to justify everyone wearing fingerless gloves by giving them a function which was explicitly stated in the comic. As such, this seems to be a great example of Goggles Do Something Unusual, but the trope description states that it only applies to eyewear.
