Biology/Photo-sensitive sneezing

Question
What's up Hintz?
I suppose this would be a biological question.  Why does light make me sneeze.  When I'm inside and I go outside where the sun is shining brightly, it makes me sneeze.  When I feel I am about to sneeze but I don't, I will look into a light or into the sun which induces one.  I have several friends who have this same trait, but other people have no idea what I am talking about.  I've always been this way and I don't know why.  Why?

Answer
Hi Paul: I know what you are talking about because it happens to me also.  If I feel like a sneeze and can't I just look at a light.  I hav enever heard of a satisfactory answer but it seems to me that since an irritation in the nose makes you sneeze then brights make you squint.  If I squint my nose starts to get itchy.
