The Mystery Of Morning Eye Crusties Explained

Waking up with crusty eyes is a common occurrence, and it is usually harmless. This eye crust, also known as rheum, is a result of the eye's natural protective process and self-cleaning system. During sleep, blinking stops, but the eyes continue to wash out waste products like mucus, tears, oil, dust, and skin cells. These waste products can accumulate and dry out, forming a crust in the corners of the eyes. While this is typically part of a healthy daily cleansing ritual, there are instances where excessive eye crust or discharge can indicate an infection or other eye conditions like blepharitis, conjunctivitis, or a stye.

Eye crust is a natural part of the eye's self-cleaning system

Waking up with crusty eyes is a common occurrence, and this crust is generally harmless. Eye crust, also known as sleep crust, eye gunk, or rheum, is a natural part of the eyes' self-cleaning system.

During the day, blinking helps to wash away dirt, dust, oil, dead skin cells, mucus, and tears from the eyes. However, when we sleep, we don't blink, and this allows for the accumulation of these waste products in the corners of our eyes. As we sleep, these waste products dry out and form a crusty film. This process is entirely natural and helps keep our eyes clean and protected.

While eye crust is typically harmless, it can sometimes indicate an infection or other eye conditions, such as blepharitis (eyelid inflammation), conjunctivitis, or a stye. If you experience excessive eye crust or other symptoms like eye pain, light sensitivity, blurry vision, or redness, it is recommended to consult an eye care professional.

To minimize or prevent eye crust, practicing good eyelid hygiene is essential. 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, it is important to remove contact lenses before sleeping and to replace them as recommended by the manufacturer.

Seasonal allergies can cause an excess of eye crust

Waking up with crusty eyes is usually harmless and a normal part of the sleep process. However, seasonal allergies can also be a cause of excess eye crust.

Seasonal allergies, such as allergic conjunctivitis, can cause eye crusting. Allergic conjunctivitis is an inflammation of the conjunctiva, which is the tissue that covers the inside of the eyelids and the white part of the eyeball. It is caused by allergens and irritants, such as pollen, dust, and mould. Seasonal allergic conjunctivitis (SAC) is the most common type of eye allergy, with symptoms typically occurring in spring, summer, or fall, depending on the type of pollen in the air. SAC symptoms often accompany the runny nose, sneezing, and nasal congestion associated with hay fever and other seasonal allergies.

People with SAC may experience chronic dark circles, known as allergic shiners, under their eyes. The eyelids may also be puffy, and bright lights may cause discomfort. The itching caused by SAC may be so bothersome that patients frequently rub their eyes, which can worsen symptoms and potentially lead to infection.

To manage seasonal allergies and reduce eye crusting, it is essential to avoid allergens that trigger symptoms. This includes staying indoors when pollen counts are high, avoiding window fans that can draw pollen and mould into the house, and wearing glasses or sunglasses outdoors to minimize pollen entering the eyes. Additionally, keeping windows closed and using air conditioning can help reduce pollen exposure.

Practicing good eyelid hygiene is also important. This includes washing the face before bed, gently cleansing the eye area with a cool washcloth, and avoiding the use of soap or cleanser in the eye region. Removing eye makeup thoroughly before bed and refraining from rubbing the eyes can also help minimize eye crusting.

Eye crust can be a sign of an eye infection

Eye crust, or sleep crust, is usually a normal part of the sleep process and the eye's self-cleaning system. However, in some cases, it can indicate an eye infection or other condition.

The crusty material found in the corner of the eyes after sleep is a mixture of mucus, tears, and skin cells. This discharge is always present, but you may notice it more when you wake up because you do not blink during sleep, allowing the discharge to accumulate and create a crusty film.

While eye crust is typically harmless, there are instances when it could signal an eye infection or other issue. If you notice an excess of discharge that is yellow, green, or white, it could indicate an infection such as bacterial or viral conjunctivitis (pink eye), blepharitis (eyelid inflammation), or a stye (infected oil gland in the eyelid or eyelash follicle). These conditions can cause the eyelids to become red, swollen, itchy, or stuck together with a crusty residue.

If you suspect you have an eye infection, it is important to seek professional eye care. An eye doctor can diagnose and provide treatment for the specific type of infection you may have. Proper eyelid hygiene practices, such as washing your face before bed, gently cleansing the eye area with a clean washcloth, and removing eye makeup thoroughly, can also help reduce the occurrence of eye crust and prevent infections.

Practising good eye hygiene can help prevent eye crust

Waking up with crusty eyes is a common occurrence, and it is usually harmless. The crustiness is caused by a mixture of mucus, tears, and skin cells that accumulate while you sleep since you are not blinking. This is a natural part of the eye's self-cleaning system.

However, if you want to reduce the amount of eye crust, practising good eye hygiene can help. Here are some tips to maintain eye hygiene and prevent eye crust:

• Wash your face before bed and gently cleanse your eye area with a clean, cool washcloth. Avoid using soap or cleanser directly in the eye area, as it may irritate the eyes.
• Thoroughly remove eye makeup before going to bed. You can use an eye makeup remover, a cotton pad, or a makeup removal wipe specifically designed for the eye area.
• Avoid touching and rubbing your eyes throughout the day. If you need to touch your eyes, make sure to wash your hands first.
• If you wear contact lenses, be sure to clean your hands before putting them in or taking them out. It is also important to replace your contact lenses regularly and not extend their life beyond the manufacturer's recommendations. Remove your contact lenses before lying down to sleep.
• If you have allergies, avoiding allergens can help improve itchy or crusty eyes.
• For people who smoke, quitting smoking may help reduce irritation to the eyes caused by cigarette smoke.
• If you have dry eyes, you can use hydrating eye drops or a saline solution to moisturize your eyes and remove any remaining film or gunk.

By following these eye hygiene practices, you can help prevent eye crust and maintain the health of your eyes.

Eye crust can be a symptom of blepharitis

Eye crust, or sleep crust, is a natural part of the eye's self-cleaning system. While awake, blinking clears away dirt, dust, oil, skin cells, and mucus. When we sleep, we don't blink, so these waste products can collect in the corners of our eyes.

However, eye crust can sometimes be a symptom of blepharitis, a common condition that causes eyelid inflammation. Blepharitis is not contagious and is usually not serious, but it can be annoying and distressing. It can affect both men and women, but one type, staphylococcal blepharitis, affects many more women than men.

The symptoms of blepharitis include irritated, swollen eyelids, which turn red or dark in color and become scaly. The edges of the eyelids become inflamed, and there may be extra crusty discharge from the eyes during the night. Other symptoms include styes (a red, painful bump on the eyelid caused by a blocked oil gland) and chalazia (a hard, painless lump on the eyelid caused by a blocked oil gland).

The main treatment for blepharitis is regularly cleaning your eyelids and keeping them free of crusts. This can be done using a gentle cleanser, such as baby shampoo, mixed with warm water, and a soft cloth or cotton swab. It is also recommended to avoid eye makeup and to remove contact lenses before bed.
