I've got a specialist that I've been seeing for about a decade, even though I've made 2 cross country moves in that time. I'm lucky to have decent insurance that makes seeing him pretty affordable, so I just set up appointments with him when I go home to visit.

One time, I had moved to another state and the tint on my car wouldn't pass inspection. It wasn’t anything particularly dark, and it was totally legal in the state I had just left... it even came from the dealership that way. I mentioned it in passing and he said, "that's dumb. You know, there's a medical exemption for how dark it can be here. Let's look it up."

Sure enough, a quick Google later, he had printed off and filled out the forms for my new state of residence. "You've got that history of migraines with painful sensitivity to light, still, right?" "Yep, sure do."

And that's how I didn't have to pay a couple hundred bucks to remove my car window tint.
