Why do so many serial killers have the same glasses? Don't call it Dahmer-core

Many have wondered about this in years past, so much so that forums like Reddit or Quora are full of conversations about it. And these days when the new series Dahmer starring Evan Peters is Netflix's most-watched show the question has resurfaced: do serial killers really all have the same pair of glasses? To be clear, they are vintage models, often but not always made of metal, usually inspired by aviation but always large compared to the wearer's face. The two most famous goggle wearers in the criminal world are undoubtedly Jeffrey Dahmer and Ted Kaczynski, better known as the Unabomber, who wore a black hoodie and black aviation goggles. Yet analyzing the annals of crime, the list grows: Ed Kemper, for example, the schoolgirl killer, wore round metallic glasses; Dennis Nilsen, nicknamed "The British Dahmer" by the media for his modus operandi, wore the same glasses as his American counterpart; even the most prolific serial killer of our time, Harold Shipman, aka Dr. Death, with a list of victims that exceeds two hundred names, wore very similar glasses; Dennis Rader, the elusive BTK Killer, was another fan of aviation glasses, while the fearsome Green River Killer, Gary Ridgway, who between the 1980s and 1990s, killed between 49 and 90 women, preferred a rectangular cellulose model that nevertheless had the same exaggerated proportions. The list goes on: Francis "Le Routard" Heaulme, Robert Hansen aka "The Butcher Baker," cultist David Koresh, responsible for the Waco massacre; the "Monster of Atlanta" Wayne Williams; Gianni Versace's killer Andrew Cunanan, and then again Gerald Stano, the "Cleveland Strangler" Anthony Sowell, women Dorothea Montalvo Puente, Judy Buenoano and Rose West, and even the famous Zodiac was described wearing a similar pair of glasses. 

The argument, though impossible to prove, holds that it was these glasses that enabled these killers to take on the appearance of quiet neighbors, family fathers, shady husbands, mild old ladies. Some also say that Dorothea Puente, accused of three murders but suspected of nine, used the glasses along with a chiffon blouse and a backcombed hairstyle to look like an octogenarian in her fifties and cast herself in the part of the aging landlady engaged in charitable work. The optics publication 2020 Magazine notes instead that in the aviator glasses «the downward angles pull the face and the eyes down with them, giving the illusion that most aviator wearers are sad, frowny-faced, or otherwise dealing with some sort of internal personal problem just beginning to bubble ot the surface. The thin, wire design of most aviators also helps to accentuate wrinkles or age lines in the faces of wearer». The association, in any case, has not prevented the killers' glasses from turning into fetishes for crime buffs: Robert Hansen's glasses for example were put up for sale online in 2008 while just a few days ago collector Taylor James put the glasses worn by Jeffrey Dahmer in prison up for sale online for $150,000. There were also other items including family photos of the Dahmers, a Bible and another pair of glasses already sold to a private collector for an amount that remains undisclosed. 

If the past is any indication of the future, however, the success of the Netflix series may bring new visibility and popularity for the aviator glasses (perhaps for the wrong reasons) perhaps freeing them from their correlation with the human type of the "creepy loner." In the meantime, those who want and can afford it can always buy Dahmer's real glasses, with the hope perhaps of not replicating his fate as well as his outfit.
