As the weather turns colder and the autumn winds pick up, many people find their eyes streaming the moment they step outside. Watery eyes are a common nuisance at this time of year, and while they’re usually harmless, persistent watering can blur your vision and make everyday tasks frustrating. The good news is that the cause can usually be identified and managed.
Why cold wind makes eyes water
Your eyes are protected by a thin tear film. Cold, dry or windy air causes this film to evaporate quickly, irritating the surface of the eye. In response, the tear glands produce a rush of watery “reflex” tears. These tears flood the eye faster than they can drain away, so they spill onto your cheeks.
The surprising link with dry eye
It sounds contradictory, but one of the most common causes of watery eyes is actually dry eye disease. When your tear film is of poor quality, often because the oil-producing glands in the eyelids aren’t working well, the eye surface becomes irritated and triggers excess reflex tearing. These tears are mostly water and don’t lubricate effectively, so the cycle continues. Moving between cold air outdoors and dry, centrally heated air indoors can make it noticeably worse.
Other possible causes
- Blocked tear ducts, more common with age, which prevent tears draining into the nose.
- Eyelid changes, where the lower lid turns slightly outwards or inwards and disrupts drainage.
- Blepharitis, inflammation of the eyelid margins.
- Allergies or infections, often with itching, redness or discharge.
What can help
- Wear wraparound glasses or sunglasses outdoors to shield your eyes from wind.
- Use a humidifier indoors and avoid sitting directly in front of heaters or car vents.
- Try warm compresses and daily lid hygiene if your eyelids are involved.
- Use lubricating eye drops recommended by your optician, rather than simply wiping tears away.
- Blink fully and take regular breaks during screen use.
