While eyelids are designed to protect the eyes from irritants and bright light, and to keep them moist and healthy during sleep, there are several reasons why some people sleep with their eyes open. This phenomenon is called nocturnal lagophthalmos and is rarely reported in medical literature. It can be caused by underlying medical conditions such as Bell's palsy, Moebius syndrome, proptosis, or auto-immune conditions such as Guillain-Barré syndrome. It can also be caused by paralysis or weakening of the orbicularis oculi muscle, which is responsible for closing the eyelids. While it is not recommended to sleep with your eyes open, some people do so unknowingly and without any adverse effects. However, if left untreated for an extended period, it can lead to severe eye damage and loss of vision.

Nocturnal lagophthalmos is the name for sleeping with eyes open or partially closed
Nocturnal lagophthalmos is the name given to the condition of sleeping with eyes open or partially closed. Lagophthalmos, meaning "hare-like eyes", refers to the inability to close one or both eyes completely. While scientists now believe that most hares sleep with their eyes closed, it is estimated that about 20% of people sleep with their eyes open. Nocturnal lagophthalmos can cause a person to sleep with their eyes open due to an issue related to the facial muscles, nerves, or skin around the eyelids.
There are several potential causes of nocturnal lagophthalmos. One cause could be paralysis or weakening of the orbicularis oculi muscle, which is responsible for closing the eyelids. This can be caused by conditions such as Moebius syndrome, a rare neurological condition affecting facial and eye movement. Structural problems or trauma may also lead to mechanical lagophthalmos rather than nerve problems. For example, protruding or sunken eyes can lead to this condition. Eye injuries, tumours, infections, and autoimmune disorders are other potential causes. In some cases, there may not be an underlying condition causing nocturnal lagophthalmos, and it may be genetic.
Nocturnal lagophthalmos can lead to reduced sleep quality due to the pain and discomfort caused by the eyes drying out. If left untreated, the eyes can become vulnerable to scratches and other injuries, as they are not protected by closed eyelids. However, generally, people will not experience serious complications due to sleeping with their eyes open.
There are several treatment options for nocturnal lagophthalmos. A doctor may prescribe artificial tears or medications to prevent the eyes from drying out. Moisture goggles can also be worn during sleep to moisturize the eyes. Applying a protective ointment to the cornea can help prevent scratches. Lifestyle changes, such as avoiding sleeping pills, may also be recommended. In severe cases, surgery may be an option, where a small gold implant is inserted into the eyelid to keep it closed.

Ablepharon-macrostomia syndrome (AMS) is a rare genetic disorder that causes a person to sleep with their eyes open
Ablepharon-macrostomia syndrome (AMS) is a rare autosomal dominant genetic disorder that affects around one in a million people. It is characterised by abnormal phenotypic appearances that primarily affect the head and face, as well as the skull, skin, fingers, and genitals. The most prominent abnormality in AMS is the underdevelopment (microblepharon) or absence of eyelids, which results in individuals sleeping with their eyes open. This condition can cause eye dryness and pain and can lead to blurry vision and scars around the eyes.
AMS is caused by a dominant mutation in the TWIST2 gene, which leads to premature maturation of chondrogenic and osteoblastic cells. This mutation results in the primary craniofacial deformities observed in individuals with AMS. The disorder is typically diagnosed at birth through physical examinations, clinical evaluations, and specialised imaging techniques such as CT scans.
The treatment for AMS focuses on relieving immediate symptoms and improving the patient's overall quality of life and physical appearance. This includes providing lubrication to the eyes to alleviate dryness and pain, and in some cases, antibiotics are prescribed to prevent infections and inflammation. Surgical methods are also available to correct malformations of the eyelids, mouth, ears, genitals, fingers, and skin. Eyelid reconstruction techniques involve recessing the levator aponeurosis and widening the shortened septum of the eyelids to descend the lid margin. Skin grafts and botulinum toxin may also be used to improve the overall appearance of the skin.
While there is currently no cure for AMS, ongoing research in Tokyo, Japan, is investigating the role of other TWIST genes, specifically TWIST1, in the development of the disorder. These studies aim to understand the underlying causes and explore more effective surgical treatments for patients with AMS.

Sleeping with your eyes open can cause eye infections and blurry vision
Sleeping with your eyes open can lead to several eye-related issues, including an increased risk of eye infections and blurry vision.
The eyelid acts as a protective barrier for the eye, preventing dust and debris from entering and causing irritation. When the eyelids are unable to close during sleep, the eyes are more susceptible to drying out, leaving them vulnerable to infections and physical damage, such as scratches. This condition is known as nocturnal lagophthalmos and can be caused by various factors, including muscle weakness, paralysis, or certain cosmetic procedures. While some people may not experience any noticeable symptoms, others may suffer from reduced sleep quality due to the discomfort caused by dry eyes.
Infections, such as conjunctivitis (pink eye), can cause itchiness, pain, swelling, redness, crustiness, and blurred vision. Without proper lubrication, the eyes become more prone to infection and physical damage, which can lead to more severe complications and even potential vision loss if left untreated for extended periods.
Additionally, people who sleep with their eyes open may experience blurry vision upon waking. This can be caused by the eyes drying out and becoming scratched during sleep. Blurry vision in the morning can also be a sign of other underlying conditions, such as glaucoma, cataracts, or Fuchs' dystrophy, which can cause similar symptoms.
To prevent eye infections and blurry vision, treatments for nocturnal lagophthalmos are available. These include the use of eye drops or artificial tears, eyelid weights, moisture goggles, or a humidifier to keep the eyes lubricated and moisturized during sleep. In some cases, an eyelid implant may be recommended for severe paralysis. Seeking medical advice is essential to receive a proper diagnosis and prompt treatment.

There are over-the-counter medications to counter the effects of dry eyes
While it is possible to sleep without eyelids, as seen in the case of a two-year-old child born with Ablepharon-macrostomia syndrome (AMS), a rare genetic disorder, it is not common. AMS affects the eyelids and mouth, causing those affected to sleep with their eyes open. This leaves their eyes without protection or a way to moisturize the first layer, leading to potential issues like blurry vision and scars around the eyes.
For those who have eyelids but experience dry eyes, there are over-the-counter medications that can help. Dry eye occurs when tear glands do not produce enough tears to lubricate the eyes, resulting in an uncomfortable and painful sensation. This can be caused by medical conditions like Sjögren's syndrome, diabetes, and contact lens use, or environmental factors such as dry air, smoke, and prolonged screen use.
Over-the-counter eye drops, often referred to as artificial tears, are a popular first-choice treatment for dry eyes. These drops come in various brands and forms, including liquid, gel, and ointment. They are designed to lubricate the eyes and provide relief from symptoms like grittiness, burning, excessive tears, and sensitivity to light. The drops vary in viscosity, with low viscosity drops offering quick relief that doesn't last long, and high viscosity drops providing longer-lasting results with a potential impact on vision. Preservative-free eye drops are also available but tend to be more expensive. These are recommended for those sensitive to preservatives or planning to use the drops for an extended period.
In addition to eye drops, home remedies like omega-3 supplements, using a humidifier, and warm compresses can also help alleviate dry eye symptoms. However, it is important to consult a healthcare provider if symptoms persist or become severe, as there are also prescription medications and medical devices available for more effective relief.

Surgery can help correct the condition, but it may cause complications
While it is possible to sleep without eyelids, it is not advisable. Eyelids play a crucial role in maintaining eye health by providing protection and moisture to the eyes. Without eyelids, one would have to constantly deal with eye infections, debris, and dryness, causing discomfort and potential long-term damage to vision.
For those with conditions that prevent them from closing their eyes during sleep, such as nocturnal lagophthalmos, Bell's palsy, or genetic disorders like Ablepharon-macrostomia syndrome (AMS), surgery can be an option to correct the issue. However, it is important to consider the potential complications that may arise.
Surgical procedures to address the inability to close the eyes typically involve adding weight to the eyelid or using skin grafts to create a functioning eyelid. In some cases, surgeons might add gold to the skin of the eyelid to increase its weight and help pull it down during sleep. While these procedures can be effective, there is a risk of complications.
One common complication is that the eyelid may not fully close even after surgery, resulting in sleeping with the eyes partially open. This can still lead to the same issues with dryness, discomfort, and eye infections. Additionally, any surgery around the eyes carries a risk of damaging the nerves that control eyelid movement, which could permanently affect the ability to shut the eyes. Cosmetic surgeries, in particular, have been associated with such nerve damage.
Furthermore, the recovery process after eyelid surgery can be lengthy. It may take months or even years to regain full functionality and mobility of the eyelid. During this time, patients may have to rely on eye drops and ointments to maintain eye moisture and protective eyewear to prevent infections.
In conclusion, while surgery can offer hope for those struggling with the inability to close their eyes during sleep, it is not without its risks and challenges. It is important for individuals considering such procedures to carefully weigh the potential benefits against the possible complications and to seek advice from medical professionals specializing in this field.
