EYE ALLERGIES

DEFINITION OF EYE ALLERGIES

Eye allergies, also known as Allergic Conjunctivitis, occur when the immune system overreacts to allergens, leading to redness, itching, swelling, and watery eyes. Common triggers include dust, pollen, pet dander, smoke, cosmetics, and air pollution.

RISK FACTORS OF EYE ALLERGIES

SYMPTOMS

  • Most prominent and classic symptom

  • Often intense and hard to resist scratching

  • May worsen in both eyes simultaneously

  • Rubbing the eyes typically makes it worse and can lead to further irritation

  • The whites of the eyes appear pink or red

  • Caused by dilated blood vessels in the conjunctiva due to inflammation

  • Often symmetrical in both eyes

    • Reflex tearing as the eyes try to flush out allergens

    • Despite the name "dry eyes," some people experience excessive tearing as a symptom

  • Eyelids may appear puffy, especially in the morning

  • Can be mild or significant depending on the severity of the reaction

  • Feels like something is in the eye

  • Often described as mild stinging or burning

  • Usually caused by inflammation or dryness associated with allergic response

TREATMENT TYPES

  • Stay indoors during high pollen counts

  • Keep windows closed and use air filters or purifiers

  • Avoid touching or rubbing your eyes

  • Wash hands and face after outdoor exposure

  • Use hypoallergenic bedding and pillowcases

  • Clean fans, vents, and dust-prone areas regularly

  • Shower before bed during allergy season

      • Help flush out allergens
