When patients describe symptoms and discomfort of the grains of sand, are really describing the increased sense of friction as the upper eyelid on the conjunctiva and cornea. This friction becomes more severe as a result of an inadequate tear film.
Sometimes, a person with dry eye excess tears running down her cheeks, which may seem confusing. This happens when the eye is not receiving enough lubrication. The eye sends a distress signal through the nervous system for more lubrication. In response, the eye is flooded with tears to try to offset the underlying dryness.
