Great image....Those would be them! The theory is if your eyes are really dry it helps keep the tears from draining out so your eyes can stay moist. The dryness I experienced was unusual I was told, but possibly related to the fact that I have a lot of allergies and my eyes tend on the dry side to begin with. It was so bad I couldn't cry even when I wanted to. I looked like a really bad B-movie actress that couldn't muster up the tears for her big scene!
