I’m not sure on the scientific accuracy of this one, but I was once told (AP Bio class, coincidentally, but not by the teacher) that the nerves that “tell” your eyes you’re looking at bright lights pass close to your sinuses, and that’s what triggers the sneeze.
Anecdotal evidence: Anytime I have a “sneezy feeling” (doncha love the scientific terms?), I can trigger the sneeze by looking at the lights or a white wall, and so avoid looking at them until I’ve found a Kleenex. OTOH, if I have the aforementioned feeling, and the sneeze doesn’t seem to be quite there yet, I can make myself sneeze by looking at a bright white surface.
According to Cecil, this seems to be a genetic tendency. Since any attempts at scientific inquiry have resulted in puzzled looks, is there any more anecdotal evidence from the Teeming Millions?
