There are many reasons for watery eyes
Watery eyes are a symptom of so many health and eye issues. According to Stephanie Marioneaux, MD, clinical spokesperson for the American Academy of Ophthalmology, it's very important to note that some causes of watery eyes could be infectious (like pink eye) or even dangerous. There are also tons of environmental factors (like dust, dry air, and smog) that can cause this symptom.
Still, you don't want to trivialize watery eyes. "The watery eye is often misinterpreted as an annoyance, and the response is to grab a tissue and blot the eye dry until you've sussed out every bit of moisture, trying to give yourself relief," says Dr. Marioneaux. In effect, the eye is bone-dry, and it stimulates more tears, perpetuating a vicious cycle that the patient encourages. She suggests having an ophthalmologist check for any eye problems if symptoms don't improve after 24 hours. Just keep in mind that your watery eyes could be because of the following reasons.
