I have this. It's weird. It's annoying.

Photic sneeze reflex is a genetic autosomal dominant trait, which causes sneezing when exposed suddenly to bright light, possibly many times consecutively. It is also referred to as photic sneeze response, sun sneezing, photogenic sneezing, the photosternutatory reflex, being photo sensitive, ACHOO syndrome, and "Achooism," with its related backronym Autosomal dominant Compelling Helio-Ophthalmic Outburst syndrome. The condition affects 17 to 35 percent of humans.
The first mention of the phenomenon is probably in the later work attributed to Aristotle (Problems, book XXXIII).
Mechanism The probable cause is a congenital malfunction in nerve signals in the trigeminal nerve nuclei. The fifth cranial nerve, called the trigeminal nerve, is apparently responsible for sneezes. Research suggests that some people have an association between this nerve and the nerve that transmits visual impulses to the brain. Overstimulation of the optic nerve triggers the trigeminal nerve, and this causes the photic sneeze reflex.
Another theory suggests that tears leaking into the nose through the nasolacrimal duct are a cause of the photic sneeze reflex. The speed of the reflex seems to favor the first theory, as it happens much too quickly for tears to be generated and drain into the nose. In addition this sneeze reflex can be brought on by a sudden inhaling of cold air or a strong flavor such as a strong mint gum. This implies an overstimulation of any nerve close to the trigeminal nerve can cause the sneeze reflex.

That's interesting. I remember my dad telling me once when I was little that if you get that "I know I have to sneeze but for some reason I can't" thing, to look into direct light and you'd sneeze.

Guys, we should start an ACHOO support group.
It suddenly feels like a handicap.

I honestly thought everyone had this sneezing reflex. I've not seen anyone that doesn't sneeze when they look towards the sun.
thats what i thought but whenever me or my dad purposefully looked at the sun to sneeze my mother would yell at us sneezing feels good like a nasal orgasm

Yes and it's really frustrating when you're about to sneeze, someone distracts you and you can't.
