The photic sneeze reflex (also known as photoptarmosis, colloquially known as "sun sneezing") is a condition of uncontrollable 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, but its exact mechanism of action is not well understood.

Famous quotes containing the words sneeze and/or reflex:
“Frau Stöhr ... began to talk about how fascinating it was to cough.... Sneezing was much the same thing. You kept on wanting to sneeze until you simply couldn’t stand it any longer; you looked as if you were tipsy; you drew a couple of breaths, then out it came, and you forgot everything else in the bliss of the sensation. Sometimes the explosion repeated itself two or three times. That was the sort of pleasure life gave you free of charge.”
—Thomas Mann (1875–1955)
“The theatre is the involuntary reflex of the ideas of the crowd.”
—Sarah Bernhardt (1845–1923)
