Sneezing in the sudden presence of bright light, especially sunlight, is a phenomenon known as sun sneezing . the photic sneeze reflex is caused by a confusion of nerve signals in pathways very near one another. Since sneezing is such a sudden and involuntary reflex, the cause is probably located in the nervous system, which is capable of transmitting signals very quickly. bright light entering the eyes sends signals along the optic nerve to the brain, which sends signals back to the eyes.The second is the sneeze reflex, in which a cranial nerve called the trigeminal nerve detects a tickling in the nose
