An interesting ‘Cake Batter’ analogy by Dr. Amber Gaume Giannoni explains the issue of watery yet dry eyes.

This strategy compares the tear film to a cake recipe, while introducing the concepts of Meibomian gland dysfunction (MGD) and reflex tearing. One could explain to the patient that, “all cake batter ingredients must be in perfect balance for a cake to turn out. If you don’t have enough oil, you can’t just add extra water and expect a delicious, moist cake.

In fact, even though extra water is added, your cake will likely turn out dry and crumbly. The tears that are responsible for lubricating the eyes are similar to a cake recipe. The components of the tears, which are mainly mucous, aqueous and oil, must be in the correct balance to keep your eyes from feeling dry. In your case, your tear-film doesn’t have enough oil. Your eyes are trying to compensate for this by tearing, which simply adds more water into the mix. Unfortunately, this isn’t the right recipe to keep your eyes feeling and seeing great.”

The proper way to relief watery dry eyes is to:

  1. Balance tear production – restore normal cell functions to tear secretion glands – lacrimal and meibomian glands
  2. Train your brain to stop crying – to stop tear over production.
