Does the sun make you sneeze?

Sunlight SneezingI read/heard once that this was caused by the optic nerve being in close proximity to the trigiminifacial (sp?) nerve. The activity on the optic nerve when going from relative dark to light somehow 'spills over' and activates the trigiminifacial (sp?) nerve to cause sneezing.

This is also commonly known as "Photic Sneezing" some people have "photic sneeze disorder" which can be quite problomatic in some cases.
