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

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.

When you close your eyes, you pinch the soap into a line between your eyelids. So it’s covering a far smaller surface area, if not being lifted from your eyeball entirely, until you open your eyes again. Some of it is of course pushed into the corner of your eye, wear dirt and stuff already gets pushed to keep your eyes clean.

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.
