Can light make you sneeze

Yes, light can trigger a sneeze in some individuals due to a phenomenon known as photic sneeze reflex. This reflex is thought to affect around 18-35% of the population and is believed to be caused by a genetic trait. When exposed to bright light, particularly sunlight, it can stimulate the optic nerve, which may inadvertently trigger the trigeminal nerve responsible for sneezing. However, this reaction varies from person to person.
