I've always known it as ''sleep'', so you could say '' I have some sleep in my eye''I don't even know what it's called in English. What do you call the "crust" or whatnot that is in the eye upon waking up? Is their a word for it? Some people refer to it as "sleep" but I don't know for sure.
In Hindi and Panjabi, it's /giDDaa/.
eye gunk, sleepydust, sleepy boogers, eye discharge, eye goop, eye crud, eye jelly, eye crust, eye bogeys, eye boogers, eye-sand, cockapia, optical crustaceans, sleepy dirt, bug dust
Besides the other English synonyms for “rheum” that have been listed so far, I have also heard it referred to as "eye cheese."I found the word “rheum”, “eye mucus”. See more at http://www.wordorigins.org/index.php/forums/viewthread/597/.
