Question:

What is that crud that forms in the corner of your eyes while you're sleeping?


Answers:

Your tears have a recipe of different materials produced by various small glands around the eye. Tears are not just water. When the watery part of the tears evaporates, what is left behind are the dried up salts, mucous and proteins. That's what your "crud" is. The normal eye with normal tears has a pretty good defense mechanism to combat the bacteria, so don't be concerned about infection.
