The sneeze reflex involves contraction of a number of different muscles and muscle groups throughout the body, typically including the eyelids. The common suggestion that it is impossible to sneeze with one’s eyes open is, however, inaccurate.[4] Other than irritating foreign particles, allergies or possible illness, another stimulus is sudden exposure to bright light – a condition known as photic sneeze reflex. The tendency to sneeze upon exposure to bright light is an autosomal dominant trait and affects 18-35% of the human population.[5]
