​Tearing​

Tearing is a healthy and normal function of the eyes as tears help to keep the eyes moist and also help clear off dust and debris. However, when you experience excessive tearing, it could be a sign of an underlying eye disorder, with tearing manifested as a symptom. 

Tearing can occur in both children and adults. Often, tearing takes place because of blocked tear ducts. These ducts help drain away tears from our eyes into our nose through tiny openings. Blockage can be due to weak eyelid muscles, reduced blinking, infection or a ‘polyp’.  In babies, tear ducts are not completely functioning for the first few months. In older people, the eye lids’ skin sags over time and moves away from the eyeball, causing excessive tearing.

Other causes of tearing include:

  • Allergies

  • Viral infections (such as conjunctivitis)

  • Eye injury

  • Disorders of the eye lid or eye lash (such as blepharitis)

  • Eye disorders

  • Dry eyes

  • Glaucoma, in which pressure builds up inside the eye

  • Irritants in the environment, such as smoke, car fumes, or wind

  • Nasal and sinus conditions

  • Certain medications, such as chemotherapy drugs

  • Common cold

  • Burns

  • Exposure to some chemicals

  • Disorders of the facial nerves 

  • Thyroid disorders​​
