Funny, after seeing some replies, I always thought that it's a universal thing. Not that it's bad or anything and it definitely is not a "syndrome" (never did it more than 1-3 times when entering sunny bright area from darkness). Must be some kind of physiological reaction and YES, it has something to do with eyes and NOTHING with nasal cavity irritation.

Photic sneeze reflex... guarantees you will never become a hot-shot fighter pilot.
It has it's advantages though.... ever had a sneeze that almost gets there but stops at the last moment, then fades only to rise again in a moment ot two? Stare at a light bulb and pow! Just tips it over the edge.

WE Don't.
I don't know about anyone else but I have never had this happen. I think if this happened to you, it was just a coincidence.
Lets think about this, if it were true, then everyone walking out of a movie theater would be sneezing, And I have never seen that.
I worked in a photo lab, and would be in the dark for an hour or so, then walk out into the light, we never had a problem sneezing.
What about people just walking outside at night and then walking into a bright house, I have never noticed people sneeze.
maybe you were walking into a dusty place.

Golly, my hubby will love this. He always sneezes when he gets in bright lights too. I always tease him about having his nerves connected wrong. Bright affects the eyes, not the nose. It means "squint" not "sneeze".
I have only met one other person who has this happen, so now I know there are at least 3 of you.
But, if you think about it, the eyes, ears and nose are all kind of connected. Sharp odors make the eyes water, getting something in your eye can make your nose run, etc. Probably not that weird.

Light stimulates the eye, causes the iris to suddenly dilate, which causes sneezing. One out of three people have photic sneeze as an inherited trait.

i think its because when you're in the dark, your eye's pupils are wide open (so you can see without much light). But when you go into bright light, your pupils dont need to be open very wide (because there is so much light). Too much light hurts your eyes, and sneezing makes you close your eyes, so it is your body's natural reaction.

Sneezing in the sunlight is actually a recessive gene in some people.

Because when the sun hits our nostrils, the hairs inside move, tickling our nasal passages.

It is called Photic sneeze reflex.

because the eyes are irritated and so when we sneeze we have to close our eyes and we are startled, this helps the adaptation.
