What's the proper word for sleep in your eyes.

I call it sleep

Wikipedia:

Mucopurulent discharge (also known as mucopurulent mattering, sleepy dust, sand and sleep) is the build-up of mucoproteins from tears found dried-out after sleep in the corners of the eye as a crystalline sludge.

During the day, tear mucus collects potentially damaging dirt on the surface of the eye. During the night this fluid collects between the eyelids, where it evaporates into a more crystalline deposit.

"Mucopurulent discharge" is the most appropriate term concluded by New Scientist (2005), offered to the publication by reader John Denvers. When referred to as "sand" it is a reference to the magic sand left by the Sandman to get children to sleep.

Thanks pal... Good researching there... Much appreciated.

I'll rep you for it next time I can...

don't trust wikipedia though....anybody can post stuff in it

for this particular case yes. but for instance, using it in a bibliography is not a good idea

Yeah, I heard that wikipedia isn't a valid source of reference at university.

thats because anyone can edit the page in the corner so data might not be valid
