What causes yellow, sticky eye discharge?

Yellow and sticky eye discharge may be caused by the following reasons: 1. Improper diet: Long-term consumption of spicy or irritating foods may lead to internal heat in the body, resulting in yellow, sticky eye secretions. 2. Bacterial conjunctivitis: Conjunctival inflammation caused by bacterial infection can lead to redness, swelling, pain, and increased eye discharge, which is typically yellow and viscous. 3. Keratitis: Usually caused by bacterial or viral infections, keratitis may also be triggered by trauma or other factors. The inflammation damages corneal epithelial cells, causing them to die and slough off, mixing with ocular secretions to form yellow, sticky eye discharge. 4. Blepharitis: A chronic inflammatory condition affecting the eyelid margins, blepharitis causes local congestion and edema, leading to increased eye secretions that appear yellow and thick in consistency.
