When soap gets to our eyes, why do they not burn when we shut them but burn when they are open.

Question

I just had a bath and some soap got to my eyes. My instant reaction was to shut them and I felt better. I stood there for five minutes with my eyes closed thinking why does this happen.

I remember reading that an open eye has something like 15 microliters of liquid on its surface and a closed eye has 4 microliters of liquid on it.
