Scary Shiny Glasses/Literature

Examples of in  include:


 * In the Dystopia classic 1984, a colleague of protagonist Winston Smith has a hostile spectacle-flash, which is the textual equivalent.
 * Likewise, in Politics and the English Language, also by George Orwell: When one watches some tired hack on the platform mechanically repeating the familiar phrases...one often has a curious feeling that one is not watching a live human being but some kind of dummy: a feeling which suddenly becomes stronger at moments when the light catches the speaker's spectacles and turns them into blank discs which seem to have no eyes behind them.
 * In the C. S. Lewis novel That Hideous Strength, the character of Professor Frost is repeatedly described as having pince nez glasses that would reflect light in such a way as to make his eyes invisible.
 * In John Bellairs' novel The House with a Clock in its Walls, the undead Mrs. Izzard has exactly this sort of glasses which even shine with ghostly radiance during a chase scene, and after her destruction, all that is left of her is her skull and her glasses.
 * In Deathly Hallows, Aberforth's glasses do this at one point when his brother (Dumbledore) is mentioned.
 * Nguyen Seth of the Dark Future novels, a truly terrifying character, has these glasses. At a couple of points he takes the glasses off, and, although his eyes are never described, the characters who see them are never quite the same again.
 * In William Golding's Lord of the Flies, Piggy's glasses do this several times.
 * Don't forget William Gibson's Neuromancer! Molly has permanent implanted mirror lenses in her sockets that make her eyes completely invisible.
 * The Major dons these in Stephen King's The Long Walk.
 * In Timothy Zahn's book The Icarus Hunt, it's mentioned offhand that the main character's boss only wears glasses so he can use them to reflect light in the eyes of whoever he's talking to. It's also mentioned that it doesn't work nearly as well over videophone.
 * Dr. Bull from "The Man Who Was Thursday" by Chesterton indulges in this trope, with rather interesting results.
 * Flavia de Luce from "The Sweetness at the Bottom of the Pie" doesn't need glasses, but she wears them anyways to invoke this trope.
 * Gideon from Scott Pilgrim uses this effect constantly, in all three media.
 * The Fighting Fantasy gamebook, Moonrunner, has a rather unnerving illustration of a mad scientist character that uses this trope.
