Can use of a nightlight in my child’s room contribute to myopia?

Recent research indicates that nightlight does not increase the risk of your child developing myopia (nearsightedness). However, some researchers have concluded that leaving a light on or other artificial light in the room of a sleeping baby younger than two years increases the risk of developing myopia. They indicate that the baby’s eyes grow excessively so that their natural focus is skewed as a result of too much nightlight.
