There is a joke about two workers sitting on a dock that illustrates why our eyes feel only the worst symptom and other symptoms are masked.
Two workers were sitting on a dock.
One says to the other, “Do you know what the best thing in the world is?”
The other says, “No, I don’t know what the best thing in the world is.”
The first one says, “Tight shoes.”
The second one says, “Tight shoes? Why are tight shoes the best thing in the world?”
The first one says, “Because when your shoes are tight your back doesn’t hurt, you don’t have a headache…”
At Not A Dry Eye Foundation, when one of us suddenly begins to experience a new symptom, we ask one another, “tight shoes?”
