An eye exam will not always show inflammation if it comes and goes.
For example if someone is allergic to
cats their eyes may be fine at the
Eye MD office but at home near the cat (or dust, smoke, dander, pollen, etc) there may be inflammation, or allergies to make up, solvents at work, may only be present at work, out doors, while wearing some types of make up.
So the answer is NO, not always.
