@dr.glen.swartwout: Your tears can get too salty. Dry eye has a physical explanation in the tear itself. When tears get too salty, they pull water off the surface of the eye. Mucin is the protein that lets the cornea hold on to moisture. Without enough mucin, the surface of the eye cannot stay wet. From my book Dry Eye Relief.
