The way black magic is done through eyes

Black magic can be done through eyes ?

Black-Eyed People (sometimes called Black Eyed Children or Bek) are young people, often children, with eyes that are solid black with no differentiation between sclera, pupil, or iris, and are occasionally reported to have blue or bluish tinted skin like that of a corpse. Those who report encounters with them often feel that the children were somehow supsupernatural and extremely dangerous though they could not explain why.

Often they can be seen playing games and singing the nursery songs "old man long legs" or "he jumped into a bramble bush" in abandoned, or near deserted areas, sometimes the reports talk of them appearing at ones doorstep usually alone or in a pair. They appear to be unusually confident yet shy children who avoid your gaze and look down hiding their eyes, but speaking with an eloquency far beyond their apparent age. Often using the mannerisms and speech patterns of an adult, they occasionally possess the voice of an adult.

They will usually attempt to talk the victim into allowing them entry into their home to use a telephone or to be safe from some unspecified danger Occasionally when seen outside the home they will immediately stop their play and stare at you, or if possible approach you asking for a place to stay or trying to talk you into giving them a ride home. 

Often, people begin to agree to their requests against their better judgement, even though the request will seem vaguely unsettling, without realizing why it is. Should you discover that their eyes are completely black, the children become very angry and insistent on you complying with their demands. Some people who have encountered Bek feel that the children may have been using some form of low-level mind control to get them to comply.
