Have you ever stepped outside on a crisp winter morning only to find your eyes watering uncontrollably? You’re not alone. While there are several contributing factors, the primary reason your eyes water in cold weather is because cold air causes evaporation, which causes your eyes to tear up in order to maintain the proper lubrication.

Understanding why your eyes water in cold weather can prevent irritation and provide relief. In this post, we’ll explore the causes of watery eyes in chilly conditions, offer preventative tips, and discuss treatments that can help you enjoy outdoor adventures all year round.

Is It Normal for Eyes to Get Watery in the Cold?

Many people experience eye tearing when exposed to lower temperatures. This reaction is generally expected and a natural response to cold weather.

Tears act as a natural lubricant, helping to keep your eyes moist and clear of debris. When exposed to cold winds or dry air, your eyes produce more tears in an attempt to maintain their moisture levels. This reflex helps shield your eyes from potential irritants and harsh environmental conditions.

However, while this reaction is normal, excessive tearing can sometimes indicate underlying issues. It’s essential to pay attention to your symptoms and consider other potential factors that might be contributing to watery eyes. 

What Causes Your Eyes to Water in Cold Weather?

Several factors can contribute to watery eyes in cold weather. The primary culprits are temperature changes, wind, and dry air, all of which can trigger your tear glands to produce more moisture.

  • Cold air often lacks humidity, making the environment drier. When the air is dry, your eyes compensate by producing more tears to maintain hydration. This natural response helps prevent the eyes from becoming too dry and irritated. 
  • Wind can cause tears to evaporate more quickly, prompting your eyes to produce more moisture. Cold weather and wind can exacerbate the tearing response, leading to watery eyes even if you just walk outside.
  • Pollen, dust, and smoke exposure can also contribute to watery eyes. While these factors aren’t specific to cold weather, they can be more prevalent during winter when windows are closed and indoor air quality may suffer. 

Being aware of these contributing factors can help you take proactive steps to manage watery eyes effectively.

How to Prevent Watery Eyes in Cold Weather

While controlling the weather is impossible, there are practical steps you can take to protect your eyes and minimize discomfort. 

  • Wear Protective Eyewear. Sunglasses or goggles can shield your eyes from wind and cold, reducing the tear response. Look for glasses with wraparound frames that offer maximum coverage and act as a barrier against wind and allergens.
  • Maintain Proper Humidity Levels Indoors. Investing in a humidifier can add moisture to the air, preventing your eyes from drying out. This can be particularly beneficial during the winter, when indoor heating can strip the air of moisture, leading to dry eyes and increased tearing.
  • Stay Hydrated. Hydration plays a crucial role in maintaining overall eye health. When your body is well-hydrated, your tear production is more likely to be balanced, reducing the risk of excessive tearing in response to cold weather.

Tips For Caring For Your Eyes in the Winter

Caring for your eyes during winter involves adopting a routine prioritizing eye health and comfort. Simple habits can significantly change how your eyes respond to cold weather conditions.

  • Aim for 7-9 hours of quality sleep each night to allow your body, including your eyes, to recover and refresh. Lack of sleep can exacerbate eye discomfort, making your eyes more susceptible to irritation and tearing. 
  • Consume foods rich in omega-3 fatty acids, such as salmon, walnuts, and flaxseeds, as these foods support eye health. Omega-3s help reduce inflammation and improve tear production, which can be particularly beneficial if you’re prone to watery eyes.
  • Wash your face with a mild cleanser to remove allergens and irritants contributing to discomfort. Consider using a warm compress to soothe tired eyes and promote relaxation, especially after spending time outdoors in the cold.

Additional Treatment for Watery Eyes

Additional treatments may offer relief if preventive measures aren’t enough to curb your watery eyes. Explore your options with an eye care professional to find the best solution for your needs.

Over-the-counter artificial tears can temporarily relieve dry eyes by lubricating your eyes and mimicking natural tears. These drops can help balance moisture levels, alleviate dryness, and reduce the tear response caused by cold weather exposure. Additionally, warm compresses can help unclog oil glands around the eyelids, improving the quality of your tears and reducing excessive tearing. 

For persistent or severe cases, consider consulting an eye care professional. We may recommend prescription eye drops or additional testing to identify potential dry eye triggers. Underlying conditions, such as an ocular surface disease, might require more targeted treatment.

Watery Eyes & Dry Eye Disease

While it may seem counterintuitive, watery eyes can sometimes indicate dry eye disease. That’s because, when your eyes are dry, they sometimes don’t produce high quality tears. Low quality tears evaporate too quickly, causing a cycle where your eyes overproduce tears to compensate. This can lead to excessive watering.

How Do I Know If I Have Dry Eye Disease?

Various factors, including age, medication use, and environmental conditions, can cause dry eye disease. Indicators of the condition include chronic eye irritation, redness, light sensitivity, or difficulty wearing contact lenses.

If symptoms persist beyond occasional discomfort, don’t hesitate to see your optometrist for help. They can diagnose your condition and offer targeted treatment options. Recognizing the signs of dry eye disease is the first step in managing dry eyes effectively
