• Perennial Allergic Conjunctivitis: Triggered by year-round allergens like dust mites, pet dander, and mold.
• Contact Allergic Conjunctivitis: Results from contact with allergens such as contact lens solutions or cosmetics.
• Giant Papillary Conjunctivitis (GPC): Associated with contact lens wear, causing large bumps on the inner eyelid.

Symptoms of Eye Allergies

Eye allergy symptoms can be bothersome.
They often include:

• Redness: The eyes appear bloodshot or pink.
• Itching: A persistent urge to rub the eyes.
• Watering: Excessive tear production.
• Burning: A stinging sensation in the eyes.
• Swelling: Puffiness around the eyelids.
• Sensitivity to Light: Discomfort in bright light.

Diagnosing Eye Allergies

Diagnosis typically involves:

• Reviewing Symptoms: A doctor will ask about your symptoms and medical history.
• Physical Examination: The eyes are examined for signs of allergy.
• Allergy Testing: Skin prick tests or blood tests may identify specific allergens.

Treatment Options for Eye Allergies

Several treatment options are available to relieve symptoms:

• Artificial Tears: Lubricating eye drops to wash away allergens and relieve dryness.
• Antihistamine Eye Drops: Reduce itching and redness by blocking histamine.
• Mast Cell Stabilizers: Prevent the release of histamine and other inflammatory substances.
• Decongestant Eye Drops: Reduce redness and swelling, but should be used short-term to avoid rebound symptoms.
• Oral Antihistamines: Can provide systemic relief but may cause drowsiness.
