Your tear ducts begin as two tiny drain openings at the inner corners of each eyelid, then carry tears into a small sac beside your nose and down into your nasal passage.
That damp corner near your nose isn’t random. It’s where drainage starts.
This guide shows you where the drain openings sit, what the hidden tubes do, and how the route ends inside your nose.
What People Mean When They Say “Tear Ducts”
Most of us say “tear ducts” as a shortcut. In reality, it’s a chain. The parts you can see are the two pinpoint openings on your eyelids. The parts you can’t see are small tubes in the lids, a small sac near the bridge of your nose, and a longer duct that opens inside the nose.
Tears are made near the outer upper corner of the eye socket, spread with each blink, then travel inward toward the drain.
Where Are Your Tear Ducts In Your Eyes?
Stand in front of a mirror with bright light. Look at the inner corner of one eye, right where the lids meet near the nose. On the edge of the upper lid you’ll see a tiny dot. On the edge of the lower lid you’ll see another tiny dot. Those are the entry points into the tear drainage system.
These openings sit on small bumps on the lid edges. They face toward the eye so they can pick up tears from the small pool that collects in the inner corner.
The Two Drain Openings You Can Often Spot
Each eye has two puncta: upper and lower. They sit close to the nose, not in the middle of the eyelid. If you’re trying to find them, don’t yank your lid down hard. A gentle pull and a sideways glance in the mirror usually works.
The tear drainage path runs from the inner eyelids into the nose, so the drain openings sit close to that inner corner.
The Short Tubes Hidden In Your Eyelids
After a tear enters a punctum, it passes through a short vertical channel, then a horizontal channel called a canaliculus. The upper and lower channels usually join before they reach the lacrimal sac. You can’t see these tubes, yet they sit close to the surface on the inner lids.
The Sac Beside Your Nose And The Duct That Heads Down
The lacrimal sac sits beside the inner corner of the eye, near the bridge of the nose. Tears collect there briefly, then drain down through the nasolacrimal duct and empty inside the nose. That’s a big reason your nose can run when your eyes water.
Tear Duct Location In The Eye Area And What Sits Nearby
If you want a fast “map,” link the drain to landmarks you already know. Use this list while you look in a mirror:
- Inner corner near the nose: the small pool of tears that feeds the puncta
- Upper lid edge near the nose: upper punctum
- Lower lid edge near the nose: lower punctum
- Under the inner lids: canaliculi
- Beside the bridge of the nose: lacrimal sac
- Inside the nose: outlet of the nasolacrimal duct
If you’ve ever tasted an eye drop, that drainage path is the reason. A portion can drain into the nose and throat. People who use medicated drops are often taught to press gently at the inner corner for a minute to slow drainage.
How Tears Move From Your Eye To Your Nose
Gravity plays a part, yet blinking does a lot of the work. Each blink spreads the tear layer across the eye surface, then nudges fluid toward the inner corner. The lid muscles also change the shape of the drainage channels, helping move tears along.

When this system is balanced, you usually don’t notice it. Your eye stays comfortably moist and your vision stays clear.
Common Spots People Mix Up With Tear Ducts
The inner corner has a few structures that can fool the eye. If someone points to “the tear duct” with a finger, they might be pointing at tissue next to the duct, not the duct opening itself.
The Pink Inner Corner Tissue
The small pink mound at the inner corner isn’t the duct. It’s normal surface tissue next to the tear pool. It can look red during irritation, allergy flares, or dry eye.
The Caruncle
The fleshy bump in the inner corner is called the caruncle. It sits close to the puncta, so it gets blamed a lot. The drain openings are on the lid edges right beside it.
The Side Of The Nose
The lacrimal sac sits beside the nose near the inner corner. Soreness or swelling there can point to a problem at the sac level, not the puncta level.
Parts Of The Tear Drainage System At A Glance
Here’s a clear map of the parts, from the lid edge to the nose. Use it to match what you see in the mirror with what’s happening under the skin.
| Part | Where It Sits | What It Does |
|---|---|---|
| Upper punctum | Upper lid edge near the nose | Drain opening that accepts tears |
| Lower punctum | Lower lid edge near the nose | Second drain opening that accepts tears |
| Upper canaliculus | Inside upper lid near inner corner | Small tube that carries tears inward |
| Lower canaliculus | Inside lower lid near inner corner | Small tube that carries tears inward |
| Common canaliculus | Where the upper and lower channels often meet | Feeds tears into the lacrimal sac |
| Lacrimal sac | Beside the bridge of the nose | Holds tears briefly before they drain |
| Nasolacrimal duct | Runs down into the nasal cavity | Final drainage tube into the nose |
| Nasal outlet | Inside the nose | Exit point where tears join nasal moisture |
Why One Eye Can Water Even When You’re Not Crying
Watering usually comes from one of two patterns: your eye makes extra watery tears, or the drain can’t keep up with the fluid you already make.
Extra watery tears are often a reflex to irritation. A dry eye surface can trigger overflow tearing. Wind, smoke, allergy triggers, a scratch, or a contact lens that’s not sitting well can do it too.
A slow drain means tears are being made at a normal pace, yet they don’t exit fast enough. Narrow puncta, swollen canaliculi, inflammation at the sac, or blockage lower in the duct can all slow flow. When the drain falls behind, tears spill over your lid margin.
A Quick Note-Taking Plan That Helps In An Appointment
If tearing is frequent, write down these details for three days. It turns vague “my eye waters” into a clear story.
- Side: left, right, or both
- Feel: gritty, itchy, burning, or no sensation
- Look: lid swelling, swelling by the nose, or a normal-looking eye
- Type of fluid: clear tears or mucus that sticks
- Triggers: screens, wind, makeup, contacts
Babies, Kids, And The Usual Early-Life Pattern
Many infants have watery eyes because the nasal outlet can stay closed at first, so tears drain slowly.
If there’s fever, strong redness, or swelling near the inner corner, seek medical care right away.
When The Drain Is The Issue: Clues By Segment
Different parts of the drainage path tend to show up with different clues. This isn’t a diagnosis, yet it helps you describe what’s going on without guessing.
| What You Notice | Where It Often Starts | What Usually Comes Next |
|---|---|---|
| Overflow tears with minimal redness | Puncta narrowing or canaliculi swelling | Eye exam and drainage testing |
| Tender swelling by the side of the nose | Lacrimal sac irritation or infection | Prompt medical assessment |
| Recurring tearing with frequent nasal stuffiness | Nasolacrimal duct or nasal outlet | Eye and nasal evaluation if it persists |
| Sticky discharge, lashes stuck together | Lid margin inflammation | Lid cleaning plan, clinician advice if ongoing |
| Gritty feeling, then watery overflow | Tear film instability on the eye surface | Dry eye plan and exam |
| One watery eye since infancy | Nasal outlet not fully open | Pediatric eye visit if it doesn’t settle |
Care Moves That Often Help Mild Irritation
If you have occasional tearing and no strong pain, these steps are often safe while you track patterns. Seek care right away for sudden vision loss, severe pain, or fast swelling.
Clean The Lid Edges Gently
The puncta sit on the lid margins. If those margins are crusty or inflamed, drainage can slow. Use a clean, warm, damp cloth to soften crusting, then wipe along the lash line with light pressure. Skip harsh scrubbing.
Try Full Blinks On Screens
Screen use reduces blinking. That can leave the tear layer patchy, then your eyes pour out watery tears that still don’t feel soothing. Every 20 minutes, do five slow full blinks and look across the room for a few breaths.
Be Careful With Inner-Corner Makeup
Heavy liner or glitter near the inner lid edge can clog the puncta. If tearing started after a new product, pause it for a week and keep the lid edges clean. If you wear contacts, swap to glasses on irritated days.
How Clinicians Check Tear Duct Flow
When tearing doesn’t settle, clinicians check the eye surface and the drain. The exam often includes the lid edges, the puncta, and the tear layer. Drainage can be tested with gentle irrigation.
