Winter Dry Eye: Why Your Eyes Feel Like Sandpaper (and What You Can Do About It)
Picture this: it’s a bright, cold Edmonton morning. You step outside, and the air instantly bites your skin. A few blocks into your day, your eyes start to sting. By the time you reach your car, they’re watering like crazy — and somehow still feel dry.
Welcome to winter in Alberta — beautiful, yes, but brutal on your eyes. At Helio Optometry, we see more patients for dry eye flare-ups between November and February than at any other time of year. Here’s why it happens, and what you can actually do about it.
Why Winter Wreaks Havoc on Your Tear Film
Your tear film — that thin, protective layer coating your eyes — is one of the most delicate systems in the body. It’s made up of three layers: oil (to prevent evaporation), water (to hydrate), and mucin (to spread everything evenly). When winter rolls in, every one of those layers comes under attack.
1. The air outside is bone-dry.
Cold air physically can’t hold much moisture. When you walk outside on a -20°C day, the humidity is often under 20%. Every blink you take in that air pulls moisture off the surface of your eyes, evaporating your tears faster than your glands can replenish them.
2. Your furnace finishes the job.
Once you’re indoors, the problem doesn’t stop. Forced-air heating — especially gas and electric systems — strips the air of nearly all remaining humidity. That’s why even cozy homes can have the same moisture level as the Sahara Desert. Combine that with ceiling fans or vehicle defrosters, and your tear film barely stands a chance.
3. Your eyelids can’t keep up.
In winter, many people blink less because of screen time and because they instinctively squint against cold air or glare from snow. That combination reduces the quality of the oil layer from your meibomian glands — and without enough oil, the watery layer of your tears evaporates almost instantly.
4. The glare and cold trigger reflex tearing — but it’s not helpful.
That constant watery tearing you notice outside isn’t real lubrication. It’s your eyes’ emergency response, flooding the surface with tears that don’t contain enough oils or mucins to protect them. The result? They run down your cheeks, and your eyes end up even drier.
5. Winter inflammation makes everything worse.
Cold, dry environments can also increase low-grade inflammation along your eyelids and tear glands. This causes a feedback loop where your eyes feel irritated, you rub them more, and the inflammation keeps your tear film unstable.
The end result: your eyes are fighting a losing battle against the environment every single day.
How to Stop Dry Eye from Taking Over Your Winter
Here are practical, optometrist-approved ways to bring moisture back to your eyes and comfort to your day:
1. Use a Warm Compress Daily
A simple warm compress helps melt the oily layer in your eyelids (the meibomian glands), keeping your tears stable longer. Use a microwaveable mask for like a bruder mask for 5–10 minutes each night — your future self will thank you.
2. Add a Humidifier (or Two)
Running a small humidifier in your bedroom or office can dramatically reduce dryness. Aim for 40–50% humidity — your eyes, skin, and even houseplants will all be happier.
3. Bring Nature Indoors
Speaking of plants, they naturally release moisture into the air. Try a few leafy friends like peace lilies, ferns, or spider plants. Bonus: they clean the air, too.
4. Blink and Break from Screens
Follow the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds. It’s a small pause that helps prevent your tears from evaporating.
5. Stay Hydrated
Even mild dehydration affects your tear quality. Keep a water bottle at your desk, or flavour your water with lemon or cucumber if plain water feels like a chore.
6. See Your Optometrist
If your eyes constantly burn, sting, or water, it’s not just “dry air.” You may have chronic dry eye disease, which needs proper diagnosis and treatment.
When to Book an Eye Exam
If you’re waking up with sore, burning eyes, reaching for drops several times a day, or finding that your vision feels “tired” by mid-afternoon, your eyes are trying to tell you something. These are early warning signs that your tear film isn’t working properly and that dryness or irritation could be affecting your comfort and vision.
At Helio Optometry, we don’t just guess what’s going on — we look closely. During your exam, your optometrist can apply special diagnostic dyes that highlight how well your tears spread and how quickly they evaporate. These tests reveal whether your eyes are producing enough tears and whether the surface of your eyes is being properly protected.
Once we know what’s happening, we’ll create a personalized plan to bring your eyes back into balance — whether that means medicated drops, in-office treatments, or simple lifestyle adjustments that make a big difference.
Don’t Let Winter Win
Your eyes deserve better than to feel gritty, sore, and tired all winter long.
