08 Dec 7 Common Causes of Dry Eye During Cold Montana Winters
Montana winters are known for their beauty, but cold temperatures, wind, and low humidity can be tough on your eyes. During winter in Billings, dry eye symptoms often become more noticeable due to increased tear evaporation and environmental stress on the ocular surface.
Understanding what contributes to winter dry eye can help you take practical steps to improve comfort and protect your vision throughout the season.
1. Low Outdoor Humidity
Cold air naturally holds less moisture than warm air. In Billings’ semi-arid climate, winter humidity levels often drop below what is comfortable for the eyes. When humidity is low, tears evaporate more quickly, making it harder for your tear film to remain stable.
2. Cold, Windy Conditions
Winter winds can accelerate moisture loss from the eyes. Even short exposure outdoors can disrupt the protective tear layer, leading to sensations of burning, grittiness, or irritation.
3. Indoor Heating Systems
Furnaces, space heaters, and fireplaces significantly reduce indoor moisture levels. Heated air pulls moisture from the surrounding environment, including the eyes, which can worsen dryness during prolonged indoor time.
4. Forced Air From Vents
Airflow directed toward your face from car heaters or office vents can intensify dry eye symptoms. Constant exposure to moving air increases tear evaporation and may irritate the eye surface.
5. Increased Screen Time Indoors
Shorter days and colder weather often lead to more time on digital devices. Extended screen use reduces your natural blink rate, which limits how often your eyes are refreshed with tears and oils needed for comfort.
6. High Altitude and Sun Reflection
Billings’ elevation contributes to drier air year-round. During winter, snow and ice reflect sunlight and UV rays, which can increase surface irritation and strain on already dry eyes.
7. Meibomian Gland Dysfunction
Cold temperatures can thicken the oils produced by the meibomian glands in your eyelids. When these glands do not release enough oil, tears evaporate too quickly. This condition, known as evaporative dry eye, may cause eyes to feel dry even if they water excessively.
