1/4 of the population has photic sneeze reflex. It just so happens that I have it too. It is when you look into a bright light and sneeze. I usually sneeze twice when it happens but it's probably different for other people. My grandfather has it so I am wondering if it runs through the family. When photic sneeze reflex occurs, you close your eyes while sneezing which may result in having car or plane accidents if you are the driver. I suggest you wear sunglasses. This probably won't help though, it doesn't for me.
Reeze
A photic sneeze reflex is a condition where exposure to bright light causes an individual to sneeze. It is estimated that around 18-35% of people experience this phenomenon. The exact cause is not fully understood, but it is believed to be due to a miscommunication between the optic nerve and the trigeminal nerve.
The photic sneeze reflex, commonly known as sun sneezing, is triggered by exposure to bright light, usually sunlight. It is a genetic trait that causes some individuals to sneeze when they suddenly move from a dark environment into a bright one.
Sunlight SneezingI read/heard once that this was caused by the optic nerve being in close proximity to the trigiminifacial (sp?) nerve. The activity on the optic nerve when going from relative dark to light somehow 'spills over' and activates the trigiminifacial (sp?) nerve to cause sneezing. This is also commonly known as "Photic Sneezing" some people have "photic sneeze disorder" which can be quite problomatic in some cases.
I am not a doctor nor any kind of researcher. Just someone who sneezes when I walk out into the sun. My idea is that when we are exposed to the bright light, we squint our eyes. When this happens it restricts our sinuses. A natural way of clearing our sinuses is a sneeze.
Sneezing multiple times in a row can occur due to several reasons, such as exposure to irritants like dust, pollen, or strong odors that trigger the sneeze reflex. It can also be a response to allergies or viral infections, where the body's defense mechanisms react strongly. In some cases, a phenomenon known as "photic sneeze reflex" can cause sneezing when exposed to bright light. Additionally, some individuals simply have a more sensitive sneeze reflex that leads to consecutive sneezes.
Your eyes shut automatically when you sneeze due to a reflex called the photic sneeze reflex. This reflex is triggered by the same nerve that controls your sneeze response, causing your eyes to close involuntarily. It is a protective mechanism to prevent bacteria or particles from entering your eyes during a sneeze.

The reflex response that a body shows in response to stimuli of an object in the nose is a sneeze. A sneeze is used to forcefully clear objects from the nose.
When a dog is on its back, it may sneeze because the position can cause irritation or tickling in the nasal passages, leading to a reflexive sneeze response.
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.
When you sneeze and it smells like pollen, it could be because you have inhaled pollen particles that are triggering your body's immune response, causing you to sneeze.
Dogs may sneeze when they are on their back because the change in position can cause irritation or tickling in their nasal passages, leading to a reflexive sneeze response.
