So I'm pretty convinced one of my main triggers for my vertigo is exposure to bright/moving light. I've noticed that my vertigo appears to be most severe when I'm up close to lights especially (i.e. using my phone in bed or in front of a laptop/computer) as opposed to watching TV from further away.

I believe there are certain tests designed to see if the cause of vertigo/dizziness is caused largely from exposure/sensitivity to lights. I was wondering if anyone had any experience with these tests (if there are any) and any general advice. I'm scheduled to have my first ENT visit next week, and would ideally like to use the right verbiage to describe my symptoms / ask for the appropriate tests to be performed.
