Tears come from the lacrimal gland. And it's found in the outer part of the upper eye. When excess tears are produced, they drain into small ducts to the nasal cavity. And if you have too many tears to drain, they'll spill out of your eyes. There's an anatomical reason why crying makes your nose run.
Your eyes are always making tears. These tears leave the eye through a small hole in the corner of the eye called the tear duct. Causes of watery eyes include: 1  Allergy to mold, dander, dust. 2  Blepharitis (swelling along the edge of the eyelid)  Blockage of the tear duct.
