Open-Eyed Sleep: How Does It Work?

how does sleeping with eyes open work

Nocturnal lagophthalmos is a condition where people sleep with their eyes partially or fully open. It is relatively common, with about 1 in 20 people experiencing it. Nocturnal lagophthalmos can be caused by various factors, including physical abnormalities, neurological problems, or other medical conditions. The condition can lead to eye health issues and sleep disruptions if left untreated. Treatment options range from simple solutions like eye drops, eyelid weights, and humidifiers to more invasive procedures like surgery.

Nocturnal lagophthalmos

People with nocturnal lagophthalmos often experience poor sleep quality due to the discomfort caused by dry eyes. The surface of the eye dries out during sleep, leading to symptoms such as a dry, gritty feeling, irritation, burning, blurred vision, and sensitivity to light. These symptoms can worsen upon waking up, and if left untreated, can lead to more severe complications and even loss of vision. However, most people are unaware they have this condition and are usually informed by someone who observes them sleeping.

There are several treatment options available for nocturnal lagophthalmos. Nonsurgical treatments focus on managing symptoms and include the use of eye drops or artificial tears to lubricate the eyes during the day, and ointments or protective cornea creams to prevent scratches at night. Moisture goggles or a humidifier in the bedroom can also help maintain eye hydration during sleep. Additionally, people can practice blinking more frequently during the day to promote eye moisture.

In more severe cases, surgical options are available. One procedure involves inserting a small weight, often made of gold, into the upper eyelid to make it heavier and help keep it closed during sleep. Another option is to use eyelid tape or surgical tape to keep the eyelids shut. In very severe cases, surgery to expand the eyelids may be recommended.

Treatment options

  • Eye drops and ointments: Eye drops can be used to lubricate the eyes during waking hours, while ointments can be applied at bedtime to keep the eyes from drying out.
  • Eyelid weights: A small weight can be placed on the upper eyelid to help keep the eye closed during sleep.
  • Tape or eye patches: In more severe cases, doctors may recommend using special tape or eye patches to keep the eyes shut at night.
  • Moisture goggles: Goggle-like devices can be worn during sleep to provide moisture to the eyes.
  • Humidifier: Using a humidifier in the bedroom can help to lessen dry eyes.
  • Surgery: In some cases, surgery may be necessary to correct physical abnormalities, repair nerves, or remove a tumour on the nerves.

If you suspect you are sleeping with your eyes open, it is important to consult a doctor or optician for a proper diagnosis and treatment plan. They may recommend additional treatments or adjustments to your sleeping environment, such as limiting alcohol or sedatives before bed and keeping the room dark to prevent light from entering and disrupting sleep.

Complications

Sleeping with your eyes open can lead to several complications, primarily related to eye health and sleep quality. Here are some of the potential issues:

Eye Health Issues:

  • Dry Eyes: One of the most common issues associated with sleeping with eyes open is dry eyes. Throughout the day, blinking helps keep the eyes moist and healthy. However, during sleep, if the eyes remain open, they can become dry and irritated. Dry eyes can lead to a range of symptoms, including pain, redness, itchiness, and a feeling of having sandpaper in the eyes.
  • Increased Risk of Infections and Scratches: Dry eyes are more susceptible to infections and can become scratched. This is because the tears produced during blinking help keep the eyes lubricated and protected.
  • Serious Eye Damage: If left untreated for an extended period, sleeping with eyes open can lead to serious eye damage and even loss of vision. This is due to the prolonged exposure and lack of protection for the eyes during sleep.

Sleep Quality and Fatigue:

  • Disrupted Sleep: Sleeping with eyes open can disrupt the quality of sleep. Research has associated nocturnal lagophthalmos with reduced sleep quality. The discomfort of dry eyes and the visual stimulation from light can cause frequent awakenings and restlessness during sleep.
  • Cycle of Fatigue: The disrupted sleep caused by sleeping with eyes open can lead to a cycle of fatigue. The affected individual may experience insomnia or worsened symptoms upon waking up, leading to a continuous state of tiredness.

Underlying Conditions:

  • Nocturnal lagophthalmos, the medical term for sleeping with eyes open, can be a symptom of underlying health conditions. These include facial nerve disorders such as Bell's palsy, Lyme disease, or injuries.
  • In some cases, it may indicate problems with the eyelids, such as physical abnormalities, eyelid surgery complications, scarring from burns, or thick eyelashes that prevent the eyelids from fully closing.
  • It could also be related to conditions affecting the muscles in the face, such as Moebius syndrome or ptosis, which can cause weakness or paralysis of the muscles involved in eye closure.

It is important to note that while sleeping with eyes open may not always lead to severe complications, seeking medical advice is crucial to rule out any underlying conditions and prevent potential eye damage.

Diagnosis

Diagnosing nocturnal lagophthalmos can be challenging because it occurs during sleep. Even if someone observes you while you sleep, small eyelid openings may be obscured by eyelashes and go unnoticed. If you suspect you have this condition, both during the day and at night, you should consult a doctor or optometrist for an examination.

The diagnostic process typically begins with a doctor observing the eyes from a distance and discussing symptoms, predisposing conditions, and family history. If the eyelids appear to be fully closed when you are awake, or they close enough that they seem adequately sealed when they are not, diagnosis can be difficult. In these cases, an ophthalmologist or optometrist can perform an eye exam to confirm the diagnosis. They may use the Korb-Blackie light test, which involves shining a transilluminator light just above the eye, over the upper tarsal plate. If light leaks onto the cheek, it indicates that the eyelid is not sealing correctly.

If you are experiencing persistent eye symptoms, particularly dry eyes that are worse in the morning, it is advisable to see a doctor for specialized testing. Symptoms of nocturnal lagophthalmos include dry, gritty-feeling eyes, irritation or burning, blurred vision, and sensitivity to light. These symptoms are caused by the surface of the eye drying out during sleep.

In some cases, nocturnal lagophthalmos may be associated with other conditions or factors, including physical abnormalities of the eyes, face, or eyelids, eyelashes that grow into the eyes, or a drooping upper eyelid (ptosis). It can also be caused by neurological problems, such as Moebius syndrome, a rare disorder causing weakness or paralysis of the facial nerves, or Bell's palsy, which causes temporary weakness or paralysis of the nerves controlling facial movements.

Prevention

If you suspect that you are sleeping with your eyes open, it is important to address it. Sleeping with your eyes open can damage your eye health and cause major disruptions to your sleep, trapping you in a cycle of fatigue.

To prevent sleeping with your eyes open, you should relax your body and mind before sleep. Breathe slowly, focus on a fixed, non-bright point, and try to clear your mind of thoughts. You can consciously think of happy and positive things to soothe your nerves and prepare for rest, helping you fall asleep quickly.

If you suspect an underlying medical condition is causing you to sleep with your eyes open, consult a doctor. They may recommend treatments such as lubricating eye drops, eyelid weights, or surgical interventions depending on the underlying cause. Doctors may also prescribe medications, such as artificial tears, ointments, or eye masks to help improve eye hydration.

In severe cases of paralysis, a gold surgical implant may be recommended. This procedure involves inserting a small gold implant into the upper eyelid to act as an eyelid weight, helping to keep the eye closed while sleeping. The implant is usually not noticeable, and the procedure has a 90% success rate.
