About the symptom

This can happen when the eye is inflamed or irritated, such as when you have allergies or an eye infection. Excess tears are the body's attempt to wash away whatever is irritating the eye.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Headache

  • Fever

  • Unilateral blindness

  • Conjunctival redness

  • Eye pain

  • Blurring of vision

Possible causes

  • Migraine

    A type of headache that typically presents as throbbing, pulsating pain on one side of the head, sometimes with associated nausea or sensitivity to light and sound. Sometimes, sensory disturbances, such as vision changes (seeing flashing lights or zigzag lines), can occur before the headache. The pain may worsen on exposure to bright lights or loud noise. Triggers for migraine include stress, poor sleep, caffeine, and hormonal changes in women.

  • Sinusitis

    Infection of the sinuses, which are cavities around the nose. The infection can be acute (lasting about a week) or chronic (lasting more than three months). It can be caused by viruses or bacteria.

  • Uveitis

    A type of eye inflammation that impacts the middle layer of tissue in the eye wall (uvea). Uveitis can be caused by infection, injury, or an autoimmune or inflammatory disease. It can be serious and lead to permanent vision loss, so early diagnosis and treatment are crucial.

  • Cluster headache
  • Intraocular foreign body
