Understanding Eye Crust: Causes and Remedies for Your Morning Discharge
What is Eye Crust?
The medical term for eye crust, often called rheum, includes normal biological materials such as mucus and dried tears. According to Ashley Hayden, M.D., a board-certified eye surgeon, this accumulation happens overnight as our blinking mechanism is inactive. It can vary in appearance from yellow and crusty to clear and watery.
Causes of Excess Eye Crust
- Dry Weather: Dry climates or cold weather aggravate conditions like chronic dry eye, leading to increased mucus.
- Blepharitis: Inflammation of the eyelids causing a white-yellow discharge due to blocked oil glands.
- Meibomian Gland Disease (MGD): Caused by blocked oil glands, resulting in thick secretions.
- Allergic Reactions/Infections: Conditions like pink eye can lead to excess discharge.
Treating Crusty Eyes
- Apply warm compresses to relieve symptoms associated with blepharitis and MGD.
- Maintain cleanliness by using lid scrubs or gentle cleansers.
- Avoid sleeping under fans to prevent tear evaporation.
- Remove contact lenses before sleeping to ensure eye health.
When to Seek Professional Help
If you find your eyes stuck together in the morning or if crusty discharge is accompanied by vision changes, contact an eye care provider promptly. Conditions that cause harm should not be ignored, especially if eye pain or irritation occurs.
