Itchy eyes in winter: causes and relief

Heating lowers indoor humidity and moving air can speed tear evaporation. Cold wind may make the eyes water, while smoke, dust or fragrances indoors can irritate the surface. Keeping windows closed can increase time around indoor allergens, including particles associated with [House Dust Mite Allergy](/conditions/house-dust-mite-allergy/) or [Pet Allergy](/conditions/pet-allergy/). When itch comes with sneezing or a runny, itchy nose, [Allergic Rhinitis](/conditions/allergic-rhinitis/) may be involved. These clues guide an assessment but do not establish a diagnosis by themselves.

Wear glasses or sunglasses outdoors to shield your eyes from wind, and avoid sitting directly beside a heater or vent. Use a clean cool compress when itching starts, wash hands before touching the eyelids, and avoid rubbing. Keep indoor air comfortably ventilated without directing strong airflow at your face. Reduce smoke and heavily scented products. A pharmacist or clinician can advise whether lubricating drops or [Allergy Medication](/treatments/medical-management/allergy-medication/) fits your symptoms.

Arrange an eye or primary-care assessment if symptoms last, recur through the season, or interfere with reading, work or sleep. Seek urgent care for pain, marked light sensitivity, reduced or blurred vision, injury, or thick discharge. Contact-lens users should remove lenses if the eye becomes red or sore and obtain advice before wearing them again.

Does this pattern suggest dry-eye irritation or [Allergic Conjunctivitis](/conditions/allergic-conjunctivitis/)? Should I change my indoor-air routine, and which treatment is safe with my other medicines?
