Sleep in your eyes, also known as eye sleep, is a common occurrence that many people experience when they wake up in the morning. It refers to the crusty or sticky substance found in the corners of the eyes, which is a combination of mucus, oil, skin cells, and other debris that accumulates while sleeping. While it is generally harmless and a part of the eye's natural protective process, excessive eye discharge or changes in colour, consistency or quantity can indicate an eye infection or underlying condition. In this paragraph, we will explore the causes and implications of having sleep in your eyes and provide insights into when it may be a cause for concern.

What You'll Learn
Eye discharge is a normal protective process
Eye discharge, or "sleep" in your eyes, is a natural process that occurs when a combination of mucus, oil, skin cells, and other debris accumulates in the corner of your eye while you sleep. This discharge is called rheum and has a protective function, removing waste products and potentially harmful debris from the tear film and the front surface of your eyes.
During the day, our eyes are constantly cleaning themselves, and we blink away any excess eye discharge. However, when we sleep, our eyes remain closed for an extended period, and the discharge collects and dries up in the corners of our eyes, forming a crust. This crust, often referred to as "sleep crust," "eye gunk," or "eye boogers," is a normal occurrence and is typically harmless.
The consistency and colour of rheum can vary depending on the amount of evaporation and the specific components. While it is usually minimal during the day due to blinking, it can increase significantly overnight. This is because our eyes are not blinking to flush out the rheum, and the meibomian gland ducts relax during sleep, allowing more of the tear film's oily substance to enter the eye.
While some eye discharge is normal, excessive or unusual discharge can indicate an eye infection or irritation. If you notice a change in colour, consistency, or quantity, it is advisable to consult a healthcare provider. Abnormal eye discharge may be a sign of conditions such as conjunctivitis, blepharitis, corneal ulcer, or dry eye disease. Therefore, it is important to pay attention to any unusual symptoms and seek appropriate medical advice if needed.

Excess discharge can indicate infection or irritation
"Sleep" in your eyes, or "eye sleep", refers to the crusty material that forms in the corners of your eyes while you sleep. This is a combination of eye debris and a hardened tear film that dries up overnight. It is a normal occurrence and is a result of the eye's protective process.
Now, onto the topic of excess discharge. The human eye is constantly cleaning itself, and some eye discharge is normal. However, if you notice an excessive amount of gunk or goo, or if the discharge looks different than usual, it could indicate an infection or irritation.
- Amount and Texture: Excessive eye discharge is typically more abundant and noticeable than normal eye discharge. It may leave a crusty residue that sticks your eyelids together.
- Colour: Abnormal eye discharge may have an unusual colour. Conjunctivitis, for example, can cause thick eye discharge that varies in colour and consistency.
- Infection and Irritation: Excessive eye discharge can be a sign of an eye infection or irritation. Conjunctivitis, blepharitis, and corneal ulcers are examples of eye conditions that can lead to increased eye discharge.
- Underlying Conditions: Eye discharge can also be a symptom of underlying issues such as allergies, dry eyes, or other problems.
- Medical Attention: If you are concerned about the amount or appearance of your eye discharge, it is recommended to consult a healthcare professional or eye care specialist.
In summary, while some eye discharge is normal, especially upon waking, excessive or unusual discharge can indicate an infection or irritation. If you notice any unusual symptoms or changes in your eye discharge, it is always a good idea to seek medical advice.

Conjunctivitis is a common cause of eye discharge
"Sleep" in your eyes, or "eye sleep", is a combination of eye debris and a hardened tear film that falls into the inner corner of the eye and dries up overnight, forming a crust. This is called rheum, and it is a completely normal residue from the eye's protective process.
However, excessive or unusual eye discharge may indicate an underlying issue. Conjunctivitis, an inflammation of the conjunctiva (the membrane that lines the inner eyelids and the white part of the eye), is a common cause of abnormal eye discharge. When the conjunctiva is inflamed, it makes the eye red or pink and triggers excessive discharge. This discharge may be watery or mucus-like and may leave a crusty residue. Depending on the cause, it can be white, yellow, or green. Conjunctivitis can be caused by bacterial or viral infections, as well as allergens like pollen, dander, and dust.
It is important to distinguish between normal "eye sleep" and abnormal eye discharge. Normal eye discharge, or rheum, is a result of the eye's protective process and varies in consistency and colour depending on the rate of evaporation and its constituents. Abnormal eye discharge, on the other hand, is typically more abundant and noticeable. It may indicate that your eye is irritated or inflamed and is working hard to clean itself. The texture, colour, or amount of discharge may be unusual.
If you are experiencing abnormal eye discharge, it is recommended to consult a healthcare provider. They can help determine if the discharge is a result of an infection, allergies, dry eyes, or other issues. While some infections may resolve on their own, others may require the help of an eye care specialist to ensure proper treatment and prevent further complications.

Blepharitis causes inflammation and crusting of eyelids
"Sleep in your eyes" is a common occurrence, often leaving you with crusty eyes in the morning. It is the result of a combination of eye debris and hardened tear film that falls into the inner corner of the eye and dries up overnight. This substance, called rheum, is completely normal and harmless, and is simply residue from the eye's protective process. However, if you notice an unusual colour, consistency, or quantity, it could be a sign of an infection or inflammation.
One such condition is blepharitis, which is characterised by crusting and inflammation of the eyelids. It is an often chronic eyelid condition that can cause eye soreness, swelling, and yellowy-green eye discharge. It can be caused by abnormal oil production from the meibomian glands, resulting in a build-up of discharge in the eyes during sleep.
Blepharitis can be caused by various factors, including bacterial infections, skin conditions, allergies, and dandruff. It can lead to other eye problems such as styes, chalazia, and recurrent bouts of pink eye (conjunctivitis). While it is usually not harmful to eyesight and isn't contagious, it can cause discomfort and irritation.
To treat blepharitis, it is important to keep the eyelids clean and free of crusts. This can be done using a gentle cleanser and warm compresses. In some cases, antibiotic ointments, eye drops, or oral antibiotics may be prescribed to resolve bacterial infections and reduce irritation. While blepharitis may not go away completely, proper eyelid hygiene and management can help control the condition.
In summary, while "sleep in your eyes" is typically harmless, it is important to be aware of any unusual symptoms that may indicate an underlying condition such as blepharitis. If you experience persistent crusting, inflammation, or other eye-related issues, it is recommended to consult an eye care professional for proper diagnosis and treatment.

Corneal ulcers are a serious infection of the cornea
"Sleep" in your eyes, or "eye sleep", is a common occurrence and generally harmless. It is a combination of eye debris and a hardened tear film that falls into the inner corner of the eye and dries up overnight, forming a crust. This crust, also known as rheum, comes in a variety of consistencies and colours, depending on the amount of evaporation and the specific components. The tear film has three components: the mucus-based glycocalyx layer closest to the eye, a water-based tear solution, and an oily substance from the meibomian gland ducts. Throughout the day, the tear film keeps the eye hydrated and removes harmful debris and bacteria.
While some eye discharge is normal, excessive or unusual discharge can indicate inflammation or infection. Signs of abnormal discharge include unusual colour, texture, or amount. For instance, conjunctivitis, an eye infection that can be viral, bacterial, or allergenic, is characterised by thick eye discharge that varies in colour and consistency. Additionally, blepharitis, a condition characterised by crusting and inflammation of the eyelids, can lead to a yellowy-green eye discharge.
Now, let's discuss corneal ulcers, a serious infection of the cornea. Corneal ulcers are open sores on the cornea, the clear, dome-shaped tissue layer at the front of the eye. They are considered a medical emergency and can lead to permanent eye damage, low vision, or even blindness if left untreated. The leading cause of corneal ulcers is infection, particularly bacterial infections. The most common bacterial species involved are Pseudomonas, Staphylococcus, and Streptococcus. However, viruses and fungi can also cause corneal ulcers.
The symptoms of corneal ulcers include a red or bloodshot eye, a watery eye, severe eye pain, and pus or other eye discharge. Corneal ulcers appear as white, hazy spots on the eye. Treatment options vary depending on the underlying cause and severity of the ulcer and may include antibiotics, antivirals, and antifungal agents.
Corneal ulcers can also be caused by non-infectious factors such as neurotrophic and neuroparalytic issues, vitamin A deficiency, or Mooren's ulcer. Additionally, ocular trauma, dry eyes, chronic dacryocystitis, and contact lens wear are common predisposing factors. It is important to note that corneal ulcers are a medical emergency, and immediate care is necessary to prevent potential vision loss and eye damage.

Frequently asked questions
It is completely normal to have some crusting or gunk in the eyes after waking up. This is called "sleep" or "eye sleep", and is a combination of mucus, oil, skin cells, and other debris that accumulates in the corner of the eye while sleeping.
Eye sleep can be wet and sticky or dry and crusty, depending on how much liquid is in the discharge. It comes in a variety of consistencies and colours, depending on how much of it has evaporated overnight, and what is in it.
Eye sleep is generally harmless and is a residue from the eye's normal protective process. However, if you notice a change in colour, consistency or quantity, it could be a sign of an eye infection or disease.
Some common eye infections that cause excess eye discharge include conjunctivitis, blepharitis, corneal ulcer, and dry eye disease.
To safely get rid of eye sleep, first wash your hands, and then use a warm flannel or compress. Avoid rubbing your eyes to remove the discharge as this can cause you to accidentally scratch your eye or pull out eyelashes.
