You may have read recently that wearing long bangs over one or both eyes could cause visual problems and even produce a lazy eye over time. It's a myth.
OK, it is sort of possible that bangs could cause a lazy eye, but only if:
1、It's a young child whose visual system is still developing.
2、One or both eyes are so well covered that the child can't even use them.
3、And the coverage is constant — all day and night.
So if your child wants Justin Bieber's long fringe from back in the day, Nicole Richie's side bangs or Veronica Lake's peekaboo look, don't worry about it.
