How to Take Care of Your Itchy, Red, or Swollen Eyes

How to Take Care of Your Itchy, Red, or Swollen Eyes

Likely Causes


When we have allergies, our body makes histamine. This makes your eye vessels bigger and irritates nerves. In 2018, a study in Nature Medicine revealed that our eyes mostly itch in the white part (conjunctiva) rather than the clear front (cornea) because of specific nerve fibers in the eye that trigger the itch. 

Symptoms: Itchy, red eyes with a runny nose or sneezing.

Triggers: Pollen, pet fur, mold, dust mites, makeup, eye drops.

Dry Eyes

You can have dry, itchy, red, or swollen eyes even without allergies. If your tear film isn't right—either evaporating too fast or not enough tears are made—your eyes can get dry and irritated.

Symptoms: Dry, itchy, swollen eyes.

Cause: Improper tear film, leading to dryness and irritation.

Other Likely Causes

  • Eczema: Can lead to itchy eyes if rash is near the eyes.
  • Blepharitis: Causes inflamed eyelids, leading to discomfort.
  • Contact Lens Infection: From improper use or care.
  • Medication Reactions: From certain medicines like antihistamines or birth control pills.
Self-Care Solutions
  • Allergies: Use anti- allergy eye drops, or allergy medications.
  • Moisture: Apply eye drops several times per day. This might last for a while. 
  • Cool Relief: Press a cool, damp cloth or ice-pack on your eyes.
  • Rinse: Gently with cold water or saline. Don’t rub!
  • Humidity: Increase to ease dry eyes.
  • Use our Eye Empower supplement: See details here.
  • Avoid irritants: Smoke, dust, strong smells.
  • Reduce screen time, blink more.
  • Use hypoallergenic eye products.
  • Wear safety glasses for protection against pollen and dust.
  • Diet: Consume foods high in vitamin A and omega-3s.
  • Supplements: Try anti-inflammatory options, such as BNH Eye Empower

Important: If improvement is not seen within 24 hours, consult a doctor.

Take care!
