Eye boogers, also known as sleep crust or rheum, are a normal buildup of mucus, oils, skin cells, and debris that collects in the corners of your eyes, especially overnight.

They're your eyes' way of staying clean and protected while you sleep, since blinking—which normally washes it away—stops during rest.

What Exactly Are They Made Of?

Eye boogers start as rheum , a thin tear film with three layers:

  • Mucin (mucus base for sticking to the eye surface)
  • Aqueous (watery part that lubricates and flushes debris)
  • Lipid (oily top layer to prevent evaporation)

When you blink, this film sweeps inward toward your nose, draining most via tear ducts—but some clumps linger and dry into crusty bits. Picture it like dust bunnies in a corner; your eyelids act as tiny brooms that can't fully clean during sleep.

Everyday Causes of Normal Eye Boogers

  • Sleep buildup : No blinking means mucus dries overnight, forming the classic morning crust. Everyone gets this—it's healthy eye maintenance.
  • Debris trap : Dust, pollen, or dead skin cells get caught in the mix.
  • Weather shifts : Dry air or wind can thicken discharge seasonally.

Pro tip : A quick splash of warm water each morning dissolves them easily.

When Eye Boogers Signal Trouble (Excess or Change)

Too much? It might not be "normal." Here's a breakdown:

Cause| What Happens| Other Signs| 15
---|---|---|---
Dry Eyes| Stringy, sticky mucus from poor tear quality or low production.| Burning, gritty feeling.|
Allergies| Extra watery mucus during pollen peaks (think spring 2026 surges).| Itchy, red eyes; sneezing.|
Infections (e.g., Conjunctivitis)| Thick, yellow/green pus-like gunk—bacterial or viral.| Swelling, pain; contagious!|
Blocked Tear Duct| Sticky overflow, often in babies or adults with swelling.| Tearing, tenderness.|
Irritants| Makeup residue, contacts, or dirt amps up production.| Temporary redness.|
Stye/Chalazion| Localized lump with crusty buildup from blocked glands.| Painful bump on lid.|

If discharge is colorful, excessive, or paired with vision changes/pain, see an eye doc pronto—could need drops or antibiotics.

Real Talk from Forums & Trends

Reddit threads like ELI5 call them "sleepy dust" or "opti-goop," with users joking about spoon-tapping crust (though extreme cases warrant a check-up). No major 2026 trends spiking "eye boogers" chatter, but dry eye talks surge in winter forums amid screen time booms.

"How many of you just wiped the corner of your eye after reading the title?" —Classic Reddit reflex!

Babies get them too (normal unless infected), and viral bugs can mimic but add fever.

Prevention & Quick Fixes

  1. Hydrate eyes : Use preservative-free drops for dryness.
  2. Clean gently : Warm compresses loosen crust; avoid rubbing.
  3. Remove makeup : Always before bed—no mascara disasters.
  1. Humidify : Especially in dry February 2026 air.
  2. Allergy prep : Antihistamine drops if pollen's trending locally.

TL;DR : Eye boogers are mostly harmless eye housekeeping, but watch for excess as a red flag. Stay clean, blink often, and consult pros for weirdness.
