The trope of a woman removing her glasses to suddenly reveal her great beauty is as familiar as it is eye-roll-inducing. She never looks that different, but her status as an erotic object changes immediately and immensely. A classic example is Dorothy Malone as a bookstore clerk in The Big Sleep (1946), but more recently there is Rachel Leigh Cook descending the stairs to the saccharine sounds of “Kiss Me” in She’s All That (1999). Give up your active gaze, this convention seems to say, and you will be alluring.
