Sleeping with your eyes open is usually associated with parasomnias, abnormal nighttime behaviours such as sleepwalking or talking in your sleep. However, it can also occur during night terrors, which are more common in children. While sleeping with your eyes open is uncommon, it is possible to sleep with your eyes closed and still experience negative consequences, especially if you wear contact lenses. Sleeping in contact lenses can reduce oxygen flow to the eye, increasing the risk of infection and dry eye. Even without contact lenses, it is normal to experience sleep or rheum in your eyes, which is a combination of mucus, oil, skin cells, and other debris that accumulates in the corner of your eye while you sleep. While this discharge can look unpleasant, it is generally harmless and even plays a protective role by removing waste and other harmful particles from the eye.

Eye discharge, or sleep, is a combination of mucus, oil, skin cells, and other debris
Eye discharge, also known as "rheum", is a combination of mucus, oil, skin cells, and other debris. It is a natural and harmless part of eye hygiene, and the eye's way of keeping itself clean. During the day, we blink away this discharge, but at night, it builds up in the corners of our eyes, along the lash line, and sometimes on our eyelashes. This is because our eyes are not blinking while we sleep, so the discharge hardens and becomes more noticeable when we wake up.
The main components of eye discharge are mucin, a thin, watery mucus produced by the conjunctiva, and meibum, an oily substance secreted by the meibomian glands. These oils help to keep our eyes lubricated between blinks. The discharge also contains whatever debris the mixture has collected, such as environmental particles or skin cells. This combination of mucus and debris is what gives eye discharge its distinctive texture and appearance.
Eye discharge can vary in consistency, colour, and quantity, depending on how much of the liquid in the discharge has evaporated. It can be wet and sticky or dry and crusty. The colour of normal eye discharge is usually clear, white, or light yellow. However, changes in the colour or consistency of eye discharge may indicate an eye infection or disease. For example, thick, crusty mucus on the eyelids and eyelashes could be a sign of blepharitis, a bacterial infection that causes redness and inflammation of the eyelids.
Abnormal eye discharge, also known as "sleep" in your eyes, is more abundant and noticeable than normal eye discharge. It may be a sign that the eye is irritated or inflamed and trying to clear itself of irritants. It might seem watery but leave a crusty residue that sticks the eyelids together. It can also be sticky or have unusual colours like yellow or green, which could indicate conjunctivitis or other eye infections.
While eye discharge is generally harmless, it is important to be aware of any changes in its appearance or any accompanying symptoms. If you experience abnormal eye discharge or other eye-related issues, it is recommended to consult an eye doctor for a professional diagnosis and treatment.

Contact lens wearers are at an increased risk of eye infections and dry eye
Contact lenses are a popular and effective form of vision correction, but they are not without risks. One of the most common issues associated with contact lens wear is dry eye. Approximately 50% of contact lens wearers experience dry eye symptoms, which can include irritation, fatigue, and discomfort. This condition is often difficult to treat and can lead to a decreased tolerance for lens wear. Dry eye can be exacerbated by low humidity environments, as the dry air can further dry out the lenses and the ocular environment. Thicker lenses with lower water content may help to ameliorate the effects of low humidity on soft contact lenses.
Contact lens wearers are also at an increased risk of eye infections due to a variety of factors. One factor is the lack of care and personal cleanliness, such as not properly disinfecting storage cases and lenses. Additionally, the use of soft lenses, especially silicone hydrogel lenses, has been associated with an increased risk of contact lens-associated papillary conjunctivitis. Mechanical forces, such as rubbing and incorrect lens insertion and removal, can also cause corneal erosion and increase the risk of infection.
The length of time contact lenses are worn also contributes to the risk of eye infections. Longer wear times, such as with extended-wear lenses, have been shown to present a greater risk of complications, including microbial keratitis and corneal invasion. Wearing contact lenses overnight is a specific risk factor for microbial keratitis, as poor hand hygiene and lens maintenance can introduce bacteria to the eye. Additionally, the preservatives present in lens care solutions may contribute to meibomian dysfunction, which can lead to dry eye and other complications.
The incidence of eye infections is lowest among PMMA and RGP lens wearers and highest among wearers of extended-wear hydrogel lenses. A controlled case study found that the risk of ulcerative keratitis was 10 to 15 times greater for users of extended-wear lenses compared to daily wear lenses. It is recommended that contact lens wearers remove their lenses at least one hour before bed to give their eyes recovery time and reduce the risk of infection and other complications.

Eye doctors refer to sleep as rheum, which is generally harmless
Eye doctors refer to sleep as "rheum" or "eye discharge". It is a combination of mucus, oil, skin cells, and other debris that accumulates in the corner of the eye while we sleep. The eye continuously produces rheum, even when we are awake. However, we do not notice it because our eyes are also producing a continuous thin film of tears that bathe the eyes when we blink, removing the rheum before it has a chance to pool and harden. When we sleep, we do not blink, so the rheum collects in the corners of our eyes or along our eyelashes, forming crust or "sleep" in our eyes.
Rheum is generally harmless and is one of the ways in which the eyes keep themselves clean, discharging waste products and any potentially harmful particles that get trapped between the tear film of the eye and the inner eyelid. It consists of mucin, a thin, watery mucus produced by the conjunctiva, and meibum, an oily substance that helps keep the eyes lubricated between blinks, along with any debris collected.
While rheum looks gross, it is a sign that your eyes are healthy and functioning normally. However, changes in the colour or consistency of the rheum may indicate an eye disease or infection. Unusual sleep discharge can be a symptom of eye conditions such as dry eyes, conjunctivitis (pink eye), blepharitis, and styes. Allergies, contact lenses, or eye injuries may also affect the production and composition of rheum.
If you experience changes in rheum discharge, it is recommended to consult an eye doctor, especially if you are also experiencing symptoms such as red or inflamed eyes, blurry vision, sensitivity to light, or eye pain. Unusual eye sleep may indicate a serious eye infection or disease, and treatment options are most effective with early diagnosis.

Night terrors are a type of parasomnia, where a person may be asleep with their eyes open
Night terrors are a type of parasomnia, a sleep disorder characterised by abnormal behaviours or events that disrupt sleep. Parasomnias occur during the latter part of the night and can happen during non-rapid eye movement (non-REM) or rapid eye movement (REM) sleep. During REM sleep, the eyes move rapidly under closed eyelids, and the heart rate, breathing, and blood pressure increase. Dreaming occurs during this stage, and the eyes may remain closed while moving. However, during a night terror, a person may be asleep with their eyes open.
Parasomnias that involve sleeping with the eyes open include sleepwalking and night terrors. Night terrors usually affect children and can be frightening for both the child and the caregiver. A child experiencing a night terror may appear frightened, scream, move wildly in bed, or even get out of bed and run around the house. They may have rapid breathing, an elevated heart rate, and excessive sweating. These episodes typically last five to ten minutes but can be as brief as 30 seconds or last a few minutes.
While sleeping with the eyes open can be associated with parasomnias, it can also be a condition called nocturnal lagophthalmos. This condition affects approximately 20% of people and involves the inability to fully close the eyes during sleep. Potential causes include facial nerve disorders, thyroid disease, genetics, aging, and post-surgical changes in facial structure. However, sleeping with the eyes open does not always indicate nocturnal lagophthalmos, as it can also occur during parasomnias.
The eyes play an important role in the sleep cycle, and their movements can provide insights into brain activity during sleep. Eye movements during sleep are normal, and during non-REM sleep, they slow down and eventually stop. As sleep deepens, eye movements may cease for a while before resuming after one or two hours during REM sleep. While the exact reason for eye movements during REM sleep is unclear, some research suggests that they enable people to change scenes while dreaming.
In summary, night terrors are a type of parasomnia where a person may be asleep with their eyes open. This condition primarily affects children and can be distressing for both the child and caregiver. While sleeping with the eyes open can be associated with parasomnias or nocturnal lagophthalmos, it is important to note that eye movements during sleep are a normal part of the sleep cycle, and dreaming occurs during REM sleep when the eyes move rapidly under closed eyelids.

Changes in the colour or consistency of rheum may indicate an eye disease or infection
While rheum—or the “sleep” in your eyes—is generally harmless, changes in its colour or consistency may indicate an eye disease or infection. Rheum is a thin mucus discharged from the eyes, nose, or mouth, often during sleep. It is a natural way for the eyes to keep themselves clean by removing waste products and potentially harmful particles that get trapped between the tear film of the eye and the inner eyelid.
When we are awake, blinking causes rheum to be washed away with tears. However, since we do not blink during sleep, rheum dries and collects in the corners of our eyes or along our eyelashes, forming the crusty material we find upon waking. This sleep crust is typically nothing to be concerned about and is considered normal.
However, if you notice changes in the colour or consistency of your rheum, it could indicate an eye infection or disease. For example, discharge that is green or yellow in colour and has a thick, pus-like consistency may indicate bacterial conjunctivitis. Watery discharge, on the other hand, can be a sign of viral conjunctivitis or allergy-related conjunctivitis. Other eye conditions associated with abnormal rheum include blepharitis and styes.
If you experience changes in the rheum discharge, especially if accompanied by symptoms such as red or inflamed eyes, blurry vision, sensitivity to light, or eye pain, it is recommended to consult an eye doctor. Treatment options for eye infections or diseases are most effective when the problem is diagnosed early.

Frequently asked questions
"Sleep" in your eyes, or ""rheum", is a combination of mucus, oil, skin cells, and other debris that accumulates in the corner of your eye while you sleep. It is a necessary component of good eye health, helping to remove waste products and other harmful debris from the tear film and the front surface of your eyes.
Sleeping with contact lenses on can harm your eye health in several ways, from reducing oxygen flow to the eye to increasing the risk of infections. It is recommended that you remove your contacts at least an hour before bed to give your eyes additional recovery time.
Symptoms of an eye infection include discharge, blurry vision, redness, and excessive wateriness. If you suspect an infection or have any other concerns, contact your optometrist right away.
During sleep, your eyes cycle through stages of rapid and non-rapid eye movement. As your sleep becomes deeper, eye movements stop for a while, and then start again after you have been asleep for one or two hours and enter REM sleep.
