Have you ever had tears in your eyes even when you weren't crying? Apparently, tears don't only appear when you're crying, but they can also appear randomly for various reasons, you know.
According to Dr. Lora Glass, M.D., assistant professor of ophthalmology and director of Ophthalmology Medical Student Education at Columbia University Medical Center tells SELF, there are 2 causes of tearing, namely excessive tear production and insufficient drainage in the eye.
Well, here are some of the causes of tears other than crying, which are quoted from various sources. Come on, see!
Too Focused On Screen
If the eyes are dry, it will be easy to produce tears. One of the causes is looking at a laptop or computer screen for too long. Symptoms that can be felt when dry eyes are a burning sensation or discomfort in the eyeball.
Launching from SELF, Dr. Joel Hunter, M.D suggests to overcome this by applying the 20-20-20 rule. For 20 minutes, take a 20-second break and focus on looking at a distant object 20 feet (6 meters) away.
Clogged Tear Duct
Launching from Web MD, tears flow out of the tear glands, then spread to the entire surface of the eyeball and flow into the corners of the eye canal. But if the duct is blocked, the tears cannot flow properly and pool on the surface of the eye. This will trigger the risk of bacterial growth, causing infection or eye injury that makes the eyes more watery.
Effects of Contact Lenses
Itchy and watery eyes are also the cause of dry eyes after wearing contact lenses. Launching from SELF, Dr. Joel Hunter, M.D says that if you constantly experience watery eyes while wearing contact lenses, it could be a sign that you're wearing them for too long or that they don't fit properly.
Reporting from The Eye Studio, to prevent this, use contact lenses as recommended by an ophthalmologist, choose contact lenses that have good oxygen permeability and avoid wearing contact lenses during a cold or flu because it can cause the risk of transferring germs to the eye.
Eyelash Problems
Ask your doctor right away if you have trichiasis or eyelashes that grow in your eyes. Launching from Healthline, if the eyelashes grow inward, the eyeball can rub against the eyelashes. This can cause irritation and redness, which can trigger the eyes to produce more tears.
Allergy
One of the most common causes of watery eyes is allergies. Launching from Web MD, allergies to exposure to pollen, pet dander or dust can cause the eyes to become red, itchy, and watery. This condition can be accompanied by other allergy symptoms, such as an itchy and runny nose, red skin or shortness of breath.
Suffering from Sleep Apnea
Obstructive sleep apnea (occurs when the airway is blocked) has also been associated with Floppy Eyelid Syndrome (FES). The syndrome is caused when the upper eyelid is more elastic than normal.
Launching from the Optomery Times, Dr. Brad Sutton, OD, FAAO., says that FES is often experienced by men who are overweight. Because the eyelids are loose and elastic, they fold easily when in contact with the pillow. This causes the eyes to dry out and produce excessive tears.
