Tears in the eye , are made all the time . They help to moisten the eye and flush away the dirt . Usually these tears drain away through tiny tear ducts .
When we blink , tears sweep across the eyes keeping the eyes moist and clean . We blink when we cough , sneeze and yawn .
If the tears forms faster than it can drain , that time it rolls down our cheeks . We can observe that every time when we cough , tears will not come out . It is only when its formation is faster than its draining .
