  • I like to think the boogers that wield your eyes shut in the morning is your body’s

  • way of saying you don’t need to open them for 5 more minutes.

  • Hi everyone, it’s Julian here for you at DNews.

  • Ok, so they aren’t actually boogers, but you know that crusty stuff in the corner of

  • your eye when you wake up?

  • Some people call it sleep, or rheum, or gound.

  • And believe it or not, it serves a purpose.

  • Dry and crusty, gunky or goopy, eye discharge in small amounts is a normal part of waking

  • up.

  • This combination of mucus, oil, skin cells and other debris in your eye serves as a protective

  • shield and allows the eye to function properly.

  • So let’s get technical for a second: the eyes of mammals are covered by a multi-layer

  • film that helps them do what theyre supposed to do.

  • Closest to the corneathe transparent front part of the eyeis a layer of mucin.

  • Mucin is made up of protein that scientists think helps clear debris and pathogens from

  • the eye.

  • On top of that is the aqueous layer, which makes up 90% of your eye’s coating.

  • This is a water-based tear solution only about as thick as a single strand of spider silk,

  • which serves many functions, including keeping our eyes hydrated and protects against infection.

  • The last outer layer is called the lipid layer.

  • It is made of an oily substance called meibum, a key part of which are fatty acids.

  • When youre awake, your body temperature keeps that layer oily, but at night when you

  • sleep, the body cools, and some of the meibum becomes a dry solidforming the basis

  • of the eye gunk that youre used to.

  • Continuous blinking throughout the day allows a film of tears to wash away the rheum from

  • our eyes, but when were asleep, we aren’t blinking.

  • [unless youre a chronic sleepwalker].

  • According to research publish by the British Journal of Ophthalmology, sleep relaxes the

  • muscles in our eyes, causing the excess meibum to seep out onto our eyelids and lashes.

  • Think of it like a zipperfrom the edge of your face in toward the nose.

  • As the eyelid closes, it pushes the material collected under the lid into the corner and

  • dries out overnight.

  • But why do we produce meibum at all?

  • Well first, the oily juices prevent us from crying constantly, unless we get our feelings

  • hurt, holding tears in place.

  • It also keeps our eyes hydrated.

  • A study published in the journal Experimental Eye Research found that rabbitseyes, when

  • lacking meibum, lost water through evaporation much faster than the normal rate.

  • Call it annoying or disgusting, but the stuff that glues your peepers together in the morning

  • is perfectly normal and important.

  • And you can be proud to say ‘I woke up like this’.

  • We're just gonna keep rolling.

  • I'm just going to keep going.

  • So now you know about eye boogers, but what about nose boogers.

  • What happens if you...eat them.

  • Yeah, gross, right?

  • I covered that in this video.

  • What do you think?

  • Do eye boogers gross you out?

  • Let us know in the comments, subscribe for more, and I'll see you guys next time on DNews.
