Question

What is the white stuff near the tip of your eyes when you wake up and sometimes during the day?

Answer 1

that's just some sand left from the Sandman :)

Answer 2

i grew up callin' them "eye boogers" haha.

i think what it really is, is just like during the night moisture leaks from your eyes, and then just kinda dries like that.

but i really have no idea.

Answer 3

You have a gland that gives off mucus and saline, it is called the lacramal gland. It is located in the outside part of your eyebrow. It gives "food" to your cornea at night and during the day. The "leftovers" are what you get in the morning.
