Something in Your Eye?
When something gets in your eye — a speck of dirt, dust, an eyelash — your body makes more tears to flush it out. Even stuff that’s too small to see, like particles in smoke or chemicals in onions, triggers this reaction. Once the problem has been swept away, your eyes should stop watering. But there are other eye problems and health issues that can make you tear up more often, too.
You might have this problem because your body doesn’t make enough tears, because they dry up too fast, or they don’t have the right balance of water, oils, and mucus. Lots of things can cause those issues, from windy days to medical conditions. Whatever the cause, your eyes react by making more tears.
This is a common cause of watery eyes for both children and adults. It can make one or both of the eyes look pink or red and feel itchy and gritty, like there’s sand in them. Infections with bacteria or viruses are the most common cause. Viral infections don’t need treatment, but you might need antibiotic eye drops if it’s bacterial.
