you can basically be dealing with one of three things when you have dry eyes. - you are not producing enough tears - You are producing enough tears but they are 'low-quality' - You are producing enough tears but they are evaporating too quick
Like, tears are actually a mixture of water and oils and stuff. And if that balance is upset, you still can get dry eyes even though you feel like you are producing plenty
Classmate: Have you considered they might be dry?
