Have you ever noticed a yellowish tinge to your tears or a yellow discharge in the corner of your eye? This can be alarming, prompting you to wonder, “Why Are My Tears Yellow?” While tears are naturally clear, the presence of yellow often indicates an underlying issue, most commonly related to blocked tear ducts and associated discharge. Understanding why your tears might be yellow and what you can do about it is crucial for maintaining eye health.
What Do Yellow Tears Indicate?
Yellow tears are not actually the tears themselves being yellow. Instead, the yellow color typically comes from discharge mixing with your tears. This discharge is often a sign that your eyes are trying to fight off an infection or are reacting to a blockage in the tear drainage system. One of the primary reasons for yellow discharge and consequently yellow-tinged tears is a blocked tear duct.
Blocked Tear Ducts: A Common Cause of Yellow Tears
Tear ducts are small channels that drain tears from your eyes into your nasal cavity. This drainage system is essential for keeping your eyes moist and clear of debris. When a tear duct becomes blocked, tears cannot drain properly and can accumulate in the eye. This stagnant environment can become a breeding ground for bacteria, leading to infection and the characteristic yellow discharge.
How Blocked Tear Ducts Cause Yellow Discharge
When tears are unable to drain due to a blockage, they can mix with mucus, bacteria, and other debris. If an infection develops in the blocked tear duct or surrounding eye area, the discharge can become thicker and change color, often appearing white, yellow, or even green. The yellow color is typically a sign of pus, which is a mixture of white blood cells, bacteria, and dead tissue – all components of the body’s response to infection. This infected discharge then mixes with your tears, giving them a yellowish appearance.

Other Symptoms of Blocked Tear Ducts
While yellow tears or discharge are key indicators, blocked tear ducts can manifest in several other symptoms, including:
- Watery Eyes: Paradoxically, blocked tear ducts often lead to excessive tearing (epiphora) because the tears cannot drain away normally and overflow onto the face.
- Sticky Discharge: The discharge associated with blocked tear ducts can be sticky and accumulate in the corner of the eye, especially after sleeping. It can cause the eyelids to stick together.
- Crusting: The discharge can dry and form crusts around the eyelids and eyelashes.
- Eye Irritation and Redness: The buildup of tears and discharge can irritate the eye, causing redness and discomfort.
- Pain or Swelling: In cases of infection, the area around the tear duct may become painful, swollen, and tender to the touch.
- Blurred Vision: Infection and excessive tearing can sometimes lead to temporary blurred vision.
- Sensitivity to Light: Infected blocked tear ducts can make the eyes more sensitive to light.
Causes of Blocked Tear Ducts
Blocked tear ducts can occur at any age, but the causes can differ between babies and adults.
In Babies:
- Congenital Blockage: Many babies are born with blocked tear ducts. In these cases, the tear duct may not be fully developed, or there might be a thin membrane blocking the duct opening. Often, this resolves on its own within the first year of life.
- Narrow Tear Ducts: Some babies are born with tear ducts that are simply too narrow to allow proper drainage.
In Adults:
- Infection: Eye infections, such as conjunctivitis (pink eye) or infections of the tear duct itself (dacryocystitis), can cause inflammation and swelling that blocks the tear duct.
- Injury: Trauma to the eye or nose area can damage the tear ducts and lead to blockage.
- Inflammation: Chronic inflammation of the nasal passages or sinuses, such as from allergies or sinus infections, can sometimes affect the tear ducts and cause them to narrow or become blocked.
- Tumors or Growths: Rarely, tumors or other growths in the nasal passages or tear duct system can cause blockages.
- Medications: Certain medications can have side effects that lead to dry eyes and, in some cases, secondary blockage of tear ducts.
- Age-Related Narrowing: As we age, the tear ducts can naturally narrow, increasing the risk of blockage.
Diagnosing Blocked Tear Ducts
If you are experiencing yellow tears or suspect a blocked tear duct, it’s important to consult a doctor. Diagnosis typically involves:
- Eye Examination: A doctor will perform a thorough examination of your eyes and tear ducts, looking for signs of blockage, infection, and discharge.
- Dye Test: A common diagnostic test involves placing a drop of dye into the eye. The doctor will then observe how quickly the dye drains from the eye. If the tear duct is blocked, the dye will drain slowly or not at all and may overflow onto the face.
- Probing: In some cases, a doctor may gently insert a small probe into the tear duct opening to check for blockages and try to clear them.
- Imaging Tests: In certain situations, especially for adults with suspected underlying causes, imaging tests like X-rays or CT scans may be recommended to visualize the tear duct system and identify the location and cause of the blockage.
Treating Blocked Tear Ducts and Yellow Tears
Treatment for blocked tear ducts and associated yellow tears depends on the cause and severity of the blockage, as well as the age of the patient.
For Babies:
- Conservative Management: Many cases in babies resolve spontaneously within the first year. Doctors often recommend conservative measures like warm compresses and gentle massage of the tear duct area to help open the blockage. Cleaning away discharge with a damp cloth is also important.
- Tear Duct Probing: If the blockage persists beyond 6-12 months or if infection is recurrent, a pediatric ophthalmologist may perform a tear duct probing procedure. This involves gently inserting a thin probe into the tear duct to open the blockage.
For Adults:
- Treating Underlying Infection: If an infection is present, antibiotic eye drops or oral antibiotics may be prescribed to clear the infection and reduce yellow discharge.
- Warm Compresses: Warm compresses can help soothe discomfort and loosen discharge.
- Surgery: For persistent blocked tear ducts in adults that do not respond to conservative treatment, surgery may be necessary. Common surgical procedures include:
- Dacryocystorhinostomy (DCR): This surgery creates a new drainage pathway for tears to bypass the blockage and drain directly into the nasal cavity.
- Balloon Dacryoplasty: A small balloon catheter is inserted into the tear duct and inflated to widen the duct and clear the blockage.
- Stenting: Small tubes (stents) may be placed in the tear duct to keep it open while it heals after surgery.
Preventing Blocked Tear Ducts and Maintaining Eye Health
While not all cases of blocked tear ducts can be prevented, especially congenital ones, you can take steps to reduce your risk and maintain good eye health:
- Practice Good Hygiene: Wash your hands frequently with soap and water to prevent eye infections.
- Avoid Rubbing Your Eyes: Rubbing your eyes can introduce bacteria and irritants, increasing the risk of infection.
- Manage Allergies: If you have allergies, manage your symptoms to reduce nasal and sinus inflammation that can affect tear ducts.
- Proper Contact Lens Care: If you wear contact lenses, follow your eye doctor’s instructions for cleaning, storing, and replacing them to prevent eye infections.
- Prompt Treatment of Eye Infections: Seek prompt medical attention for any signs of eye infection to prevent complications like blocked tear ducts.
When to Seek Medical Advice for Yellow Tears
It’s important to see a doctor if you or your child experience yellow tears or any other symptoms of a blocked tear duct, especially if accompanied by:
- Persistent or worsening yellow discharge.
- Eye pain or increasing redness.
- Swelling around the eye.
- Blurred vision.
- Sensitivity to light.
- Symptoms that don’t improve with home care.
Yellow tears are a sign that something is not quite right with your eye health. While often caused by treatable conditions like blocked tear ducts and infections, it’s essential to seek professional medical advice to determine the underlying cause and receive appropriate treatment to prevent complications and maintain healthy vision.
