When doctors talk about dry eyes as a source of pain, perhaps that's a light term. Dry eyes aren't exactly the most painful thing in the world, but if they get dry enough, if they get irritated enough, people will actually pull at them, they'll rub them, and then they can have even more problems because the dryness causes what physicians call a scratched cornea. When the corneal area gets scratched, it's one of the most sensitive parts of the body. As a result, that pain that can occur can be excruciating. Fortunately, it only lasts about 24 hours. The cornea heals relatively rapidly.
