Eye mucus, also known as eye discharge, is a natural fluid made by the eyes. It helps keep the eyes healthy by providing moisture and protection from irritants. Usually, eye mucus builds up during sleep, but it can also happen during the day, especially if the eyes are irritated.

There are two main types of eye mucus: normal and abnormal. Normal eye mucus is usually clear or a little cloudy and is easy to wipe away. On the other hand, abnormal eye mucus can be thick, colored, or come with symptoms like redness or itching, which may signal a problem.

Common Causes of Eye Mucus

Eye mucus, also known as eye discharge or "sleep" in the eyes, can occur for various reasons. Here are some common causes:

1. Conjunctivitis (Pink Eye)

Conjunctivitis, an inflammation of the conjunctiva (the clear membrane covering the white part of the eye), is a common cause of eye mucus. It can be triggered by viral, bacterial, or allergic infections, leading to watery or thick discharge, along with redness and irritation.

2. Dry Eye Syndrome

When the eyes do not produce enough tears, or the tears evaporate too quickly, the eyes become dry and irritated. In response, the body may produce mucus to help lubricate the eyes, leading to stringy or sticky eye discharge.

3. Blepharitis

Blepharitis is the inflammation of the eyelids, often due to bacterial infection or seborrheic dermatitis. It can result in a buildup of mucus, crusting, and irritation along the eyelid margins.

4. Allergies

Allergic reactions, such as those caused by pollen, dust, or pet dander, can trigger eye irritation and lead to excessive mucus production. This is often accompanied by itching, redness, and watery eyes.

5. Sinus Infection (Sinusitis)

A sinus infection can cause mucus to drain into the eyes due to the close proximity of the sinuses to the eyes. This drainage can result in eye discharge, along with facial pain, pressure, and congestion.

6. Foreign Object or Irritation

If a foreign object (like dust or an eyelash) enters the eye, it can cause irritation, leading to increased mucus production as the eye tries to flush it out. This may result in a clear or thick discharge.

7. Contact Lens Wear

Wearing contact lenses, particularly for long hours, can lead to dryness and irritation of the eyes. The body may produce excess mucus as a protective response to discomfort or a mild infection related to the lenses.

8. Eye Infections (Corneal or Eyelid Infections)

Infections of the cornea (keratitis) or the eyelids can cause significant mucus discharge. These infections may also be accompanied by pain, blurred vision, and sensitivity to light.

Home Remedies and Treatments

When to See a Doctor

If your symptoms persist or are accompanied by pain, vision changes, or severe redness, it's essential to see a doctor. These may be signs of a more serious underlying condition that requires medical treatment, such as an eye infection or an allergy.
