Whenever someone has to sneeze my family tells them to look at a bright light. This makes most people sneeze.
Recently someone told us that there is a special word or phrase for this.
Is this so? Does anyone know the word?
The photic sneeze reflex (also known as photoptarmosis, Autosomal Dominant Compelling Helio-Ophthalmic Outburst Syndrome (ACHOO) and colloquially sun sneezing) is a condition that causes variable difficulty to control 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.
