It’s annoying. You’re sitting at your desk or walking through the grocery store and suddenly, you’re dabbing at your face because there are tears in my eyes for seemingly no reason at all. People ask if you’re okay. You aren't sad. You aren't watching a Hallmark movie. Your eyes are just... leaking.
It feels like a paradox. How can your eyes be "watery" if the most common cause is actually Dry Eye Syndrome (DES)? Honestly, it sounds like a bad joke. But the biology behind it is actually pretty fascinating, if a bit frustrating to live with daily. When your eyes get too dry, your lacrimal glands panic. They send a "flood the engine" signal, resulting in a gush of low-quality tears that don't actually lubricate anything. They just roll down your cheeks and make your eyeliner run.
The Three Layers of Your Tears
Most people think a tear is just salty water. It isn't. According to the American Academy of Ophthalmology, a healthy tear film is a complex sandwich of three distinct layers. If any part of this sandwich is missing, you end up with constant moisture that does zero work.
First, you have the oily (lipid) layer. This is produced by the meibomian glands. It’s the "lid" on the pot that keeps the water from evaporating. If you don't have enough oil, the water disappears into thin air, leaving your eye parched and irritated. Then there’s the watery (aqueous) layer, which is the bulk of what we see. It cleans the eye and washes away bits of dust or rogue eyelashes. Finally, the mucus layer helps the whole mess stick to the surface of the eyeball. Without mucus, the water just slides off like rain on a waxed car.
When you have tears in my eyes constantly, it’s usually because the watery layer is overcompensating for a lack of oil. It's called epiphora. Basically, your eye is trying to fix a drought with a flash flood. It doesn't work.
Why Your Eyes Water When It’s Cold or Windy
Have you ever stepped outside on a crisp October morning and immediately felt like you were weeping? You're not alone. Wind is a literal vacuum for moisture. When the air hits your cornea, it triggers a reflex. This reflex arc involves the trigeminal nerve, which senses the cooling and drying effect on the ocular surface.
The nerve sends a frantic 911 call to the brain. The brain responds by hitting the "produce tears" button. Hard.
The problem is that these "reflex tears" are mostly water. They lack the proteins and lipids found in "basal tears"—the ones that stay on your eye all day to keep things smooth. So, you get a face full of water, but two minutes later, your eyes feel scratchy and "sandy" again. It's a vicious cycle. Experts like Dr. Christopher Starr from Weill Cornell Medicine often point out that environmental triggers are the most common reason people complain about excessive tearing during the winter months.

Allergies and the Histamine Ghost
Sometimes it’s not the wind. Sometimes it’s the cat. Or the ragweed. Or the dust mites living in that rug you’ve had since college.
When an allergen hits your eye, your immune system loses its mind. It releases histamine. This chemical makes your blood vessels leak and your tissues swell. It also turns on the waterworks. Allergic conjunctivitis is a massive reason for finding tears in my eyes at weird times. You'll know it's allergies if your eyes also itch like crazy. If they don't itch, it's probably something else.
The Clogged Pipe Problem: Dacryostenosis
Think of your eye's drainage system like a sink. You have the faucet (the glands) and the drain (the puncta). The puncta are tiny holes in the corners of your eyelids. They lead to the nasolacrimal duct, which empties into your nose. That's why your nose gets runny when you cry.
But what if the drain is clogged?
This is called dacryostenosis. It can happen because of an infection, a stray bit of makeup getting lodged in there, or just aging. As we get older, those tiny drain pipes can narrow. If the drain is blocked, the normal amount of fluid your eye produces has nowhere to go. It backs up. It overflows. Suddenly, you have tears in my eyes while you're just trying to read a book.
In babies, this is super common because their ducts haven't fully opened yet. In adults, it usually requires a specialist to flush the duct out. It's a quick procedure, but it sounds terrifying to anyone who hates things near their eyes.
Blepharitis and Meibomian Gland Dysfunction (MGD)
This is the big one. This is the "secret" reason behind about 86% of dry eye cases. Blepharitis is basically dandruff of the eyelashes. Bacteria or tiny mites (Demodex, if you want to be grossed out) live at the base of your lashes. They create inflammation.

This inflammation plugs up the meibomian glands. Remember the oil layer we talked about? This is where it’s made. If these glands are plugged, you get no oil. If you get no oil, your tears evaporate instantly. If your tears evaporate, your brain sends more water.
Boom. Constant tearing.
You might notice your eyelids look a bit red or "crusty" in the morning. That’s a dead giveaway. Managing this usually involves warm compresses. You're basically trying to melt the thickened oil (which becomes the consistency of toothpaste instead of olive oil) so it can flow again.
Digital Eye Strain: The 2026 Reality
We spend too much time looking at screens. I'm doing it right now. You're doing it right now. When we stare at a phone or a laptop, we stop blinking.
Seriously.
The normal blink rate is about 15-20 times per minute. When we're focused on a screen, that drops to about 5-7 times. Blinking is the "windshield wiper" action that spreads the tear film and squeezes the oil glands. When you don't blink, your eyes dry out in patches. The reflex kicks in, and suddenly you have tears in my eyes while scrolling through TikTok. It’s your body’s way of screaming at you to look at a tree for a few minutes.
When to Actually Worry
Most of the time, watery eyes are just a nuisance. But sometimes they’re a signal. If you have tears in my eyes accompanied by any of these, you need a doctor:

- Pain: Real, sharp pain, not just a scratchy feeling.
- Vision changes: If things look blurry and stay blurry after you blink.
- A "lump" near the tear duct: This could be an infection called dacryocystitis.
- The feeling of something stuck: If you can't get that "grit" out, it might be a corneal abrasion.
Managing the Moisture: Actionable Steps
Stop ignoring it. If you're constantly dabbing your eyes, you're actually making it worse by irritating the skin around the lids.
The 20-20-20 Rule works. Every 20 minutes, look at something 20 feet away for 20 seconds. And blink intentionally. It feels stupid, but it works. It resets the tear film.
Warm compresses are king. Use a clean washcloth with warm (not scalding) water and hold it over your closed eyes for five minutes. This softens the oils in your glands. Do it while you listen to a podcast. It’s the single most effective "at home" fix for the majority of people dealing with MGD-related tearing.
Check your environment. If you have a fan blowing directly on your face while you sleep, stop it. If your office is incredibly dry, get a small humidifier. You're trying to stop the evaporation before the reflex tears start.
Artificial tears actually help. It sounds counterintuitive to add drops to a watery eye. But you aren't adding water; you're adding "fake" basal tears that have the right balance of salt and lubricants. This tells your brain, "Hey, we're good here," and the reflex tearing stops. Look for preservative-free drops if you’re using them more than four times a day. Preservatives like BAK (benzalkonium chloride) can actually damage the eye surface over time.
Omega-3 Supplements. There is some decent evidence from the DEWS II study that high-quality Omega-3s (fish oil or flaxseed) can improve the quality of the oil your glands produce. It takes about three months to see a difference, so don't expect a miracle overnight.
If you've tried the drops and the compresses and you still have tears in my eyes every time you try to have a conversation, go see an optometrist or ophthalmologist. They have tools like LipiFlow or IPL (Intense Pulsed Light) therapy that can jumpstart those clogged oil glands in ways a warm washcloth simply can't.
Stop thinking it's just "one of those things." Your eyes are trying to tell you that the surface of your cornea is stressed out. Listen to them. Better tear quality means clearer vision and a lot less squinting at the world. It’s worth the effort to fix the plumbing.
