Up to 25% of us can't escape it. We walk out of a dark movie theater into the bright sunlight, and then it happens: "Ah choo!" This sneeze reflex is a genuine phenomenon. So what causes it?
Close association between the eye’s optic nerve and nerves causing the sneeze reflex may explain why an estimated 5-25% of people sneeze with sudden exposure to bright sunlight or other light sources.
Sudden bright stimulation of the eye that occurs after a person has become adapted to darker surroundings is thought to bring on the condition, known as photic sneeze reflex. The reflex also is called Autosomal Dominant Compelling Helioophthalmic Outburst Syndrome, known by the acronym ACHOO. (Not making this up. Really.)
