It is soothing to watch babies sleeping peacefully. However, you may occasionally notice your baby sleeping with eyes open and wonder why it happens. It is common for some babies to sleep with completely or partially open eyes, which is called lagophthalmos in medical terms.

However, it is recommended to seek pediatric evaluation if you notice any other symptoms or anything that prevents them from closing their eyelids. Read on to know why babies sleep with their eyes open and what you can do about it.

You might feel uneasy to see your baby sleeping with their eyes open. However, you need not worry much, as most of the time, sleeping with the eyes partially or fully open is common and may not be associated with any medical condition. The medical term for this condition is known as nocturnal lagophthalmos.

According to the National Sleep Foundation, about 20% of people experience it, and it even occurs in babies, and most of them outgrow it (1).

But why do some babies sleep with their eyes open? Read on to find out.

Why Do Babies Sleep With Their Eyes Open?

Although it is a common and harmless condition, it could cause concern in some rare cases. The exact reason for nocturnal lagophthalmos is not known yet. However, here are a few possible reasons.

  1. Genetics: If someone in your family or your partner has this condition, there is a chance of your baby inheriting it (1).

  1. Rapid eye movement sleep (REM): Babies’ sleep patterns are such that they have a longer REM sleep than adults due to an underdeveloped nervous system. This could be one of the reasons your baby sleeps with their eyes open (2).
  1. A disorder at birth: In some rare cases, babies may sleep with their eyes open if they have a congenital disorder, such as a defect in their facial nerves nerve  (3).

If your pediatrician has ruled out any congenital disabilities, you need not worry about your child sleeping with open eyes as long as it doesn’t cause eye irritation. If you notice your child’s eyes becoming dry, you might want to check with your pediatrician to prescribe some eye drops or ointments to protect your baby’s cornea from drying up (4).

If you are uncomfortable watching your baby sleep with their eyes open, you can wait until they drift off to deep sleep and gently close their eyelids. However, make sure you do not wake the child or startle them.

When To Call The Doctor?

Usually, babies outgrow this condition and sleep with their eyes closed. But, if it’s been a while (one or two months), and your baby is still sleeping with their eyes open, or if you find additional symptoms such as wide-open eyes or eye redness, talk to your pediatrician.

In the case of congenital disorders of the eyelids, you need to work with your pediatrician to get the proper treatment.

Babies are often seen sleeping with open eyes, and this is seldom a cause of concern. Hence, if you have noticed your babies sleep with their eyes open, rest assured that your baby is safe and will most likely grow out of this habit in a month or two. However, although the condition itself is harmless, check for any additional symptoms that are interfering with their sleep or causing irritation, such as red eyes. In such a case, consult your pediatrician since it may indicate an underlying issue.
