What Causes Eye Discharge? | Seattle Eye Guide
What Is “Sleep in the Eyes”?
Eye discharge (“sleep” or rheum) is a natural mix of mucus, oils, and skin cells that cleans your eyes overnight. While common, changes in color, texture, or amount may signal issues needing attention. For Seattle residents, seasonal allergies and dry indoor air can intensify this morning buildup.
Common Causes in the Pacific Northwest
Natural Cleaning
Small, clear/white crust upon waking is normal.
