Prevention

Most blocked tear ducts cannot be prevented. The majority of blocked tear ducts are present at birth (congenital) when the thin tissue covering the tear duct does not open normally.

But you can help prevent some conditions that can cause blocked tear ducts, such as:

• Sinus or eye infections. If you have symptoms of these types of infections, see your doctor right away for treatment. For more information, see the topic Sinusitis or Pinkeye.
• Facial injuries. Wear a helmet when you play contact sports such as football.

If your baby has blocked ducts, limit his or her time in the wind, cold, and sunlight. This can help prevent symptoms from getting worse.
