Black-eyed children are described as superficially resembling human children or teenagers between the ages of 6 to 16.
Notes on verification
Multiple independent folklore/paranormal sources (Snopes, academic urban legends site, Spooky Isles, Business Standard, Grokipedia) consistently describe black-eyed children as resembling kids aged 6-16, confirming this is an accurate representation of the legend as commonly told, though it describes folklore rather than a verified phenomenon.
