That’s the prevailing theory, yes, but as far as I’ve found there’s not empirical evidence to back it up. The theory does make perfect sense to me, though!
Also, as a sufferer, I’ve noticed it almost always requires sunlight or something with close to the same frequencies. Most artificial lights don’t trigger it.

Artificial lights absolutely trigger it for me. They just have to be bright.

“Bright” is kind of a spectrum though. Sometimes a light is just bright enough that you can trigger a sneeze, but only if you focus on it. Other times that same light will almost trigger a sneeze with focus, but not go completely over the edge. That’s a very annoying feeling when that happens.

Interesting! I’ll update my post, it makes sense there would likely be variability in how it presents due to biology. My experience isn’t necessarily the default.
