Nightlight

An Associated Press article captured the attention of
  readers with the headline "Night lights bad for kids?"
  The article was based on a 1999 study at the University
  of Pennsylvania and Children's Hospital of Philadelphia,
  in which parents were surveyed about the lighting
  conditions under which their children slept between birth
  and age 2 (lamp, night-light, or no light) and whether or
  not their children developed nearsightedness (myopia).
  The purpose of the study was to explore the effect of a
  young child's nighttime exposure to light on later
  nearsightedness.
