I learned about the Photic Sneeze Reflex when discussing the frustration of cancelled sneezes (you know, when you feel one coming on, but then it just doesn’t happen and it leaves you feeling weird.) He told me, “When that happens, I just look at a light.” I had no idea what he meant. Meanwhile, he thought it was normal for everyone. We both learned something that day.

An entry for ACHOO syndrome in the National Library of Medicine, by Laura Dean from 2012 claims 1 in 4 people will be pushed over the edge to a sneeze when they already have one on the edge, but “pure” photic sneezing is “far less common” although there is no number given, so I have no idea how rare or common it is to just straight up sneeze from light without already having to sneeze
