can looking into the sun make you sneeze
The photic sneeze reflex (also known as, Autosomal Compelling Helio-Ophthalmic Outburst (ACHOO) and colloquially sun sneezing) is a condition that causes sneezing in response to numerous stimuli, such as looking at bright lights or periocular (surrounding the eyeball) injection. The condition affects 18-35% of the population in the United States, but its exact mechanism of action is not well understood.
