As the temperatures drop along the Central Coast, many people start noticing an unwelcome companion: dry, irritated eyes that flare up as soon as the heater switches on. Even though winter in Santa Barbara and San Luis Obispo County is relatively mild, indoor heating can make dry eye symptoms feel much worse.
At Pacific Eye Surgeons, our specialists see this seasonal pattern every year. The good news? With a proper evaluation and advanced treatments like LipiFlow®, long-lasting relief is absolutely achievable.
The Real Reason Heating Makes Your Eyes Dry
Indoor heating changes your environment in ways your eyes feel immediately. When warm air circulates, it affects the protective tear film that keeps your eyes comfortable, hydrated, and functioning.
Low Humidity Makes Tears Evaporate Faster
Heating systems—even small space heaters—pull moisture out of the air. With less humidity inside your home, car, or office:
- Tears evaporate more quickly
- The surface of the eye dries out
- Burning, stinging, and irritation develop
Warm Air Flow Disrupts the Tear Film
Many homes and workplaces rely on forced-air heating, which pushes warm air directly into your environment. Air blowing toward your face accelerates tear evaporation and destabilizes the tear film.
Common triggers include:
- Car heaters
- Ceiling vents in offices
- Bedroom wall units
- Space heaters near your feet or desk
Winter Habits Make Dry Eye Worse
When the days shorten and evenings get cooler, most people spend more time indoors on digital devices. Screen use reduces your blink rate—meaning tears do not spread evenly over the eye.
Contact Lenses Lose Moisture Quickly
Lenses are notorious for drying out in warm indoor air. If you wear contacts, the combination of heat and lower humidity can make your eyes feel irritated or fatigued much faster than usual.
The Importance of a Full Dry Eye Evaluation
Because dry eye can stem from many different causes, the first step toward effective treatment is a comprehensive ocular surface evaluation. At Pacific Eye Surgeons, we go beyond surface symptoms to pinpoint the specific factors contributing to your dryness.
Our dry eye assessments may include:
- Measurement of tear quantity
- Analysis of tear film composition
- Screening for Meibomian gland blockage
- Evaluation of eyelid inflammation
- Blink pattern assessment
- Review of environmental and lifestyle triggers
- Contact lens–related dryness evaluation
Understanding the underlying issue allows us to build a treatment plan tailored specifically to your eyes.
