Urban legends referring to Black Eyed Kids began to appear in 1998, starting with a newsgroup posting by journalist Brian Bethel reporting of a meeting with two unusually confident and eloquent children who attempted to talk him into giving them a ride in his car. Bethel said in his post that he nearly opened the door to admit the children, even though he found them vaguely unsettling, until he realized that their eyes were completely black, with no iris or pupil. He reports that, as soon as he realized this, the children became angry and insistent, and he drove away quickly. His posting implies that the children may have been using some form of low-level mind control to induce him to open the car, perhaps a form of neurolinguistic programming judging by what is reported of their speech patterns and diction.

Since this post, there have been other reports of similar experiences in other parts of the country. These accounts are similar to Bethel’s in that they generally involve the children’s request that the teller let them inside their car or house, frequently using an excuse such as “I need to get home to my mother,” or something that implies the child is in need.

Urban legends involving the Black Eyed Children generally do not explain the cause of the children’s eye color or the origins of the children themselves. Some imply they could be ghosts or demons, specifically vampires: the tales frequently emphasize that the children must be admitted or invited into the house or car in question, and in this way are reminiscent of some vampire legends.

It’s late, it’s dark and you’re in the middle of nowhere. Perhaps you’re walking down a lonely stretch of moonlit road, maybe you’re in a desolate parking lot trying to get your car started or perhaps you’re nestled in the warmth of your own home reading yourself to sleep; whatever the circumstance, you find yourself in an isolated locale when you’re suddenly startled by a sharp knock at the door or window. You look up from your steering wheel or cautiously pull back the curtain to see… wait for it… a pair of thin, trendily dressed, usually olive skinned teenagers.

Sounds pretty anti-climatic, right? But just wait; these aren’t your average, ordinary scallywags. These adolescents have something horribly wrong with them — something almost none of the witnesses notice at first glance — it’s their eyes. These “creatures” have no white corneas, no colorful irises, just a pair of big, black, shark-like eyes that inspire abject horror in all who have claimed to have seen them.
