Strange things happen to people’s bodies all the time. Some individuals, for example, have the ability to shoot water from their eyeballs.
Does spitting up fluid from the eyes pose a health risk for those who do?
Eyes may moisten for a variety of causes other than weeping. Anything that irritates the eye may produce tears when the eye attempts to clear it.
The researchers found that when one squirts water from one’s eye, the pressure produced by the squirt causes fluid from the eyes to back up into a sac on the bridge of the nose (where glasses normally sit). This sac, which is a component of the tear duct system, is scientifically known as the lacrimal sac.
The nasolacrimal ducts, which are also known as the tear ducts, are small tubes in the lower and upper eyelids that collect and drain the tears. The ducts connect to fluid-filled sacs.
Dr. Michelle Andreoli, an ophthalmologist at Northwestern Medicine Regional Medical Group in Illinois and a clinical representative for the American Academy of Ophthalmology, stated, “This drainage system is basically the sewer for the eye’s tears”. Drainage of tears is evident in upper and lower eyelid inner corners close to the nose at a tiny hump that opens tear ducts.
In most cases, this fluid drains out of the nose or throat. When someone tears, the liquid from the eyes runs down the tear ducts, into the sac, and then to the nose and throat, causing the nose to become runny.
Air or liquid is usually prevented from backing up into the eye via valves along the route. However, some individuals may be able to squeeze or shoot fluids from the sac and duct with pressure. According to case studies published in the Journal of Otolaryngology and Rhinology in 2020, it may even produce a high-pitched noise.
Andreoli said in an email to Live Science that “some individuals may suffer reflux or overflow via the tear duct.” As a result of sneezing forcefully or blocking one’s nose, air or fluid from the lacrimal sac bubbles out the tear duct, forcing it to overflow.
Perform the Valsalva technique, which involves taking a deep breath, closing your lips, pinching your nose, and blowing for 10 to 15 seconds while holding your breath. Because of the pressure involved, this technique often causes the ears to “pop” and puts strain on the nasal cavity. To increase the amount of pressure, some individuals pour milk or blow smoke down the duct.
It was suggested by the authors of the case study that individuals who can push air or liquid through their tear ducts may have aberrant valves, enabling the fluid to flow back into the duct and eye.
Andreoli said these party tricks are entertaining but not hazardous, which is excellent news for eye health since the tear duct system is a key player in eye health.
According to Andreoli, if a tear duct is clogged, tears may back up onto the surface of the eye, causing irritation. “Irritation and discomfort,” in addition to “watering and redness,” are potential side effects to consider.
