As someone who wears glasses, something that always irritates me in films/tv/books/fics is when a character's glasses are removed for them by their partner with whom they're getting intimate with. An act often combined with a comment about 'seeing better'. Like fuck off, surely they see better with specs!!
At least have the decency to let the glasses wearing character remove their own specs when they want during intimate scenes, for reasons such as the specs are getting uncomfortable or steaming up (does happen).
