Sleepy Eyes: Why Do I Wake Up Like This?

Waking up with crusty eyes, or sleep, is a common occurrence that can be caused by a buildup of mucus, tears, and skin cells in the corners of the eyes during sleep. This discharge, also known as rheum, is a result of the eye's natural protective process and can vary in consistency and colour depending on its composition and evaporation rate. While generally harmless, excessive or unusual eye discharge may indicate an infection, inflammation, or other underlying conditions, especially if accompanied by other symptoms such as itching, swollen eyelids, or blurred vision. Practising good eyelid hygiene and consulting an eye doctor when needed can help address concerns related to waking up with sleep in the eyes.

The technical term for sleep in the eyes is rheum

Rheum is a natural part of the eyes' self-cleaning system. During the day, blinking wipes away dust, old cells, extra mucus, and tears from the eyes. While sleeping, the waste products are still being washed out of the eyes, but without blinking, they can pool in the corner of the eyes, forming a crust. This crusty material found in the corner of the eyes after sleep is called sleep crust, eye gunk, or eye goop.

The appearance of rheum can vary, with some people experiencing white, cream-coloured, or light yellow crusts, while others may have eye lashes stuck together with a watery or solid discharge. In most cases, rheum is harmless and can be easily wiped away with a warm washcloth. However, if you notice a change in colour or an increase in the amount of rheum, it is recommended to consult an eye doctor.

While rheum is a natural occurrence, there are certain conditions that can increase its production. For example, in the case of allergic conjunctivitis, the buildup of rheum can be significant, causing difficulty in opening the eyes upon waking without prior cleansing. Additionally, if you have allergies, you may notice extra eye rheum during certain times of the year.

To reduce the amount of rheum in the eyes, proper eyelid hygiene is important. This includes washing your face and gently cleansing the eye area with a clean, cool washcloth before bed, avoiding the use of soap or cleanser in the eye area, and thoroughly removing eye makeup. It is also recommended to avoid touching or rubbing the eyes and to wash your hands before doing so if necessary.

It is a combination of mucus, tears, and skin cells

Waking up with crusty eyes, or "sleep" in your eyes, is a common occurrence that is generally harmless. This phenomenon is caused by a combination of mucus, tears, and skin cells that accumulate in the corners of your eyes while you sleep. During the day, blinking helps to wipe away these waste products, but at night, they can build up, creating a sticky, glue-like substance that may cause your eyelids to stick together.

The technical term for this eye "sleep" is rheum, and it is a result of your eyes' normal and healthy daily cleansing process. Throughout the day, your eyes are constantly washing themselves, using a combination of tears and mucus to trap and clear away debris, dust, and old cells. While you sleep, this waste continues to be washed out, but without the blinking that normally clears it away, it can pool in the corners of your eyes, creating eye crust or rheum.

There are several factors that can contribute to an increase in eye crust. For example, dry eye syndrome, caused by insufficient tear production or evaporation, can lead to a sticky, stringy mucus residue. Regular or prolonged screen use can also decrease eye lubrication, contributing to dry eye symptoms. Additionally, certain health conditions, medications, and allergies can play a role in the amount of eye crust experienced.

While eye crust is typically harmless, it is important to maintain proper eye hygiene to prevent a buildup. This includes practices such as washing your face and gently cleansing the eye area with a clean, cool washcloth before bed, as well as removing eye makeup thoroughly. If you wear contact lenses, it is recommended to remove them before sleeping. In the morning, you can use a warm washcloth to gently wipe away any eye crust that has formed overnight.

In most cases, eye crust is a normal part of your eyes' cleansing process. However, if you notice unusual discharge in terms of texture, colour, or amount, it could indicate an infection or other condition. For example, if you see green or yellow colouring, it is best to consult an eye doctor. Proper eye hygiene, such as washing your hands before touching your eyes, can also help prevent infections caused by bacteria and germs.

It is generally harmless and is a result of the eye's natural cleansing process

Waking up with crusty eyes or "sleep" in your eyes is generally harmless and is a result of the eyes' natural cleansing process. This sticky, glue-like substance is a combination of mucus, tears, old skin cells, and environmental debris that accumulates in the corners of your eyelids while you sleep. It is called rheum, and it occurs because you are not blinking during sleep to wash away this waste.

Throughout the day, blinking helps to wipe away dust, old cells, extra mucus, and tears from your eyes. However, during sleep, your eyes continue to produce tears and mucus, and the waste products can build up and dry, forming a crust. This is why you may find your eyelids stuck together when you wake up.

The consistency and colour of rheum can vary depending on how much of it has evaporated and the specific composition. It is typically white, cream-coloured, or light yellow. While it is generally harmless, if you notice a change in colour (such as green or yellow), consistency, or quantity, it could indicate an infection or other eye conditions.

Practising good eyelid hygiene can help minimize the buildup of eye crust. This includes washing your face and gently cleansing your eye area with a clean, damp washcloth before bed, removing eye makeup thoroughly, and avoiding touching or rubbing your eyes. Additionally, removing contact lenses before sleeping and maintaining proper contact lens hygiene are important.

In summary, waking up with "sleep" in your eyes is typically harmless and a result of your eyes' natural cleansing process. However, if you notice any changes in colour, consistency, or quantity, it is recommended to consult an eye doctor to rule out any potential infections or other eye conditions.

However, if you notice a change in colour, consistency or quantity, it could be a sign of an infection

Eye sleep, or sleep crust, is a common occurrence and is generally harmless. It is a result of the eye's natural protective process, which continues while you sleep. During the day, blinking wipes away dust, old cells, extra mucus, and tears from your eyes. While you sleep, you don't blink, but these waste products are still washed out of your eyes. Some of this waste may build up and create a crusty film on the corner of your eyelids.

However, if you notice a change in colour, consistency, or quantity, it could be a sign of an infection. For example, if the discharge is green or yellow in colour, especially if it is accompanied by blurry vision, light sensitivity, or eye pain, it may indicate a serious eye infection or disease. Conjunctivitis, or pink eye, is a common eye condition associated with abnormal eye discharge. It is an inflammation of the conjunctiva, the thin membrane that lines the white of the eye, and can be caused by bacteria, viruses, or allergies. It typically results in itchy, red, irritated eyes and white, yellow, or green eye mucus, which can form a crust along the lash line while you sleep.

Another potential cause of abnormal eye discharge is blepharitis, an inflammation of the eyelids that can lead to sore eyes, swelling, and a yellow or green eye discharge. A corneal ulcer is another possibility, which is a sight-threatening infection of the cornea caused by eye trauma or a severe infection. Symptoms include eye inflammation and redness, along with heavy eye discharge or a pus-like substance. If you are experiencing these symptoms, it is important to seek urgent medical attention to increase the chances of saving your sight.

Practising good eye hygiene can help prevent a buildup of rheum

Waking up with rheum or eye gunk is a common occurrence. This is because, during sleep, you are not blinking, and the mucus that your blinking would normally clear away can pool and dry in the corner of your eyes. This is a natural and healthy process, and the rheum itself is harmless. However, practising good eye hygiene can help prevent a buildup of rheum and ensure eye health.

Good eye hygiene includes a few simple steps. Firstly, always wash your face before bed and gently cleanse your eye area with a clean, cool washcloth. It is important to avoid using soap or cleanser in the eye area as this can cause irritation. Removing eye makeup thoroughly before bed is also important, and you may wish to use an eye makeup remover, cotton pad, or makeup removal wipe for this.

It is also recommended to avoid touching and rubbing your eyes throughout the day. If you do have to touch your eyes, be sure to wash your hands first. Contact lens wearers should remove their lenses before bed and follow the manufacturer's recommendations for replacement. It is also important to use the appropriate solutions to clean the lenses.

Additionally, protecting your eyes from harsh environmental conditions such as wind and smoke can help maintain eye health. Taking regular breaks from screen time and increasing your Omega-3 intake can also be beneficial. Staying hydrated by drinking plenty of water can help maintain adequate tear production and keep the eyes lubricated.

By following these eye hygiene practices, you can help prevent a buildup of rheum and promote overall eye health.
