Sleep in the eyes, also known as eye sleep, refers to the crusty material that accumulates in the corners of the eyes after sleep. This is a combination of mucus, tears, oil, skin cells, and other debris that collects while blinking is reduced during sleep. While it may be unpleasant, this substance, also known as rheum, is generally harmless and is a normal part of the eye's protective process. However, excessive eye discharge or changes in its colour, consistency, or quantity can indicate underlying issues such as eye infections, allergies, or dry eyes, requiring medical attention.

Eye discharge, or 'sleep', is a combination of mucus, oil, skin cells, and other debris
Eye discharge, or sleep in your eyes, is a combination of mucus, oil, skin cells, and other debris that accumulates in the corner of your eyes while you sleep. It can be wet and sticky or dry and crusty, depending on how much of the liquid in the discharge has evaporated. The medical term for sleep in the eyes is rheum.
During the day, blinking washes away protective mucus. However, since we blink much less frequently at night, the mucus collects in the corners of the eyes and sometimes along the lash line, forming sleep. Mucus is used to remove waste products, keep the eyes moist, and protect them from debris. The mucus in your eyes is formed in the conjunctiva, a membrane around the eye and lining the inside of the eyelids. Oil is produced by the meibomian glands near the lower eyelashes.
While sleep in the eyes is generally harmless, excessive eye discharge can be a sign of inflammation or infection. If you notice an unusual colour, consistency, or quantity, it could indicate an underlying issue. For example, conjunctivitis, or pink eye, is an inflammation of the conjunctiva that can cause a large amount of discharge. Other potential causes of abnormal eye discharge include blepharitis, a blocked tear duct, dry eye disease, and corneal ulcers.
If you are experiencing abnormal eye discharge, it is important to consult an eye care professional for a proper diagnosis and treatment. They can help determine whether the discharge is due to an infection, allergies, or another issue. In the meantime, you can help prevent irritation and infection by removing makeup before sleep and avoiding touching your face or eyelids during the day.

'Sleep' in eyes is called rheum and is a normal occurrence
The "sleep" in your eyes, also known as eye crust, eye gunk, or eye boogers, is called rheum and is a normal occurrence. It is a combination of mucus, tears, oil, old skin cells, and environmental debris that accumulates in the corners of your eyes while you sleep. During the day, blinking washes away this protective mucus, but at night, it collects and forms a crust when exposed to air, which is why we often wake up with rheum in the corners of our eyes.
The medical term for this substance is rheum, and it serves an important protective function for our eyes. The mucus in rheum helps to remove waste products and harmful debris, such as bacteria, from the tear film and the front surface of our eyes. Additionally, it keeps our eyes moist and lubricated, which is essential for eye health.
While rheum is typically harmless, it is important to be aware of excessive or unusual eye discharge, as this could indicate an underlying issue. For example, if the rheum changes colour, usually to a yellow or green hue, and is accompanied by eye pain, light sensitivity, blurry vision, or redness, it could be a sign of an eye infection or eye disease. In such cases, it is recommended to consult an eye doctor promptly for an accurate diagnosis and treatment.
Contact lens wearers may also experience more rheum due to various reasons, including eye infections, discomfort from dry and irritated eyes, or increased rubbing of the eyes while adjusting to the lenses. Additionally, certain eye conditions, such as blepharitis (inflammation of the eyelids) and Meibomian gland dysfunction (MGD), can lead to abnormal oil production, resulting in increased eye discharge.
While rheum is a natural and protective occurrence for our eyes, monitoring any changes in its appearance and seeking professional advice when necessary is essential for maintaining good eye health.

Excessive eye discharge may indicate an infection or allergies
"Sleep" in the eyes, or eye discharge, is a combination of mucus, tears, oil, skin cells, and other debris that accumulates in the corner of the eye while we sleep. This is a normal occurrence, and the eye routinely clears this away. However, excessive or unusual eye discharge may indicate an infection or allergies.
Excessive eye discharge can be a sign of inflammation or infection. If the texture, colour, or amount of discharge is unusual, it may be a cause for concern. Normal eye discharge is white or pale cream in colour, and it is usually crusty and found along the lash line and in the corners of the eyes upon waking. Abnormal eye discharge is more abundant and noticeable, and it may leave a crusty residue that sticks the eyelids together.
Infection-causing bacteria can infect the eyelids and eyelashes, causing redness and inflammation. The eyelids may thicken and form dandruff-like scales. A thick green, yellow, or grey mucus discharge could indicate a bacterial infection. Conjunctivitis, or pink eye, is a common eye infection that causes inflammation of the conjunctiva, the membrane that lines the inner eyelids and the white part of the eye. It can be caused by bacteria or viruses and is highly contagious. Conjunctivitis typically causes a watery or mucus-like discharge that may be white, yellow, or green in colour.
Allergies can also cause excessive eye discharge. Allergic conjunctivitis is triggered by allergens such as pollen, dander, dust, and other common irritants. It can also be caused by an allergic reaction to chemical pollutants, makeup, contact lens solutions, and eye drops. The discharge associated with allergic conjunctivitis is typically watery, and both eyes are usually affected.

Conjunctivitis, or 'pink eye', is a common eye infection that can cause eye discharge
"Sleep" in your eyes, or eye discharge, 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 normal and necessary component of good eye health, serving as a protective mechanism to remove waste products and other irritants from the tear film and the front surface of your eyes.
However, excessive or unusual eye discharge can be a sign of an eye infection or other issues. Conjunctivitis, often referred to as pink eye, is a common eye infection that can cause eye discharge. It is characterised by inflammation of the conjunctiva, the thin membrane that lines the sclera (the white part of the eye) and the inner surface of the eyelids. This inflammation gives the eye its characteristic pink or reddish appearance.
Conjunctivitis has several potential causes, including bacterial and viral infections, allergies, and irritants. Viral pink eye, caused by the same virus as the common cold, is the most common and contagious form. It usually starts in one eye, causing excessive tears and watery discharge, and then spreads to the other eye within 24-48 hours. Bacterial pink eye can result in yellowish, greenish, or white discharge, which may crust along the lash line and in the corners of the eyes. Allergic conjunctivitis, on the other hand, is triggered by allergens like pollen, dust, or chemical pollutants and is typically not contagious. It often affects both eyes and is characterised by watery discharge.
While pink eye is usually not serious and very treatable, it is important to see a doctor for an accurate diagnosis and treatment. Antibiotic treatment is effective for bacterial infections, while viral infections typically resolve on their own. To prevent the spread of conjunctivitis and ensure proper treatment, it is recommended to wash hands frequently and avoid touching the eyes.

Blepharitis, an inflammation of the eyelids, can also cause crusting and eye discharge
"Sleep" in your eyes, or eye gunk, is a combination of mucus, tears, oil, skin cells, and other debris that accumulates in the corner of your eye while you sleep. It is a normal, protective function of the eye, helping to remove waste products and other irritants.
However, excessive eye discharge can be a sign of inflammation or infection. If the discharge has an unusual colour or texture, or is accompanied by other symptoms like blurred vision or light sensitivity, it could indicate a serious eye infection or disease.
One such eye disease that can cause crusting and eye discharge is blepharitis, an inflammation of the eyelids. It is a common condition that can cause painful tenderness and discomfort. It is characterised by redness, thickening, and flakey or scaly crusting along the eyelids and eyelashes. Over time, a sticky plaque or biofilm forms along the lids, causing lash loss, clogged glands, infections, and other complications.
There are two types of blepharitis: anterior and posterior. Anterior blepharitis affects the outside of the eye, where the eyelashes attach to the eyelid. It is usually caused by bacteria on the skin or dandruff from the scalp or eyebrows. Posterior blepharitis affects the outside of the inner edge of the eyelid, the part that touches the eye. This type happens when the oil glands in the eyelids get clogged, often due to common skin conditions like rosacea and scalp dandruff.
Treatment for blepharitis focuses on managing symptoms and keeping the eyelids clean and free of crusts. Doctors may prescribe steroid eye drops, ointments, or pills to reduce inflammation and treat bacterial infections. Warm compresses and eyelid scrubs can also help to manage blepharitis.
