Which type of conjunctivitis is most commonly associated with contact lens wear?

• A. Allergic conjunctivitis
• B. Bacterial conjunctivitis
• C. Giant Papillary Conjunctivitis
• D. Viral conjunctivitis

Answer: (C)

Giant Papillary Conjunctivitis is the one most linked to contact lens wear. It stems from a chronic, immune-mediated reaction to mechanical irritation and deposits (such as proteins) on lenses, solutions, or the tear film. This ongoing irritation causes large, cobblestone-like papillae to form on the upper eyelid’s conjunctiva, along with itching, mucous discharge, and increased lens intolerance. Treating it involves improving lens hygiene, reducing or stopping lens wear, and using anti-inflammatory eye drops or stabilizers under supervision; switching to different lens types or daily disposables can also help.

Allergic conjunctivitis is driven by environmental allergens and typically presents with itching and redness but isn’t specifically tied to contact lens use. Viral conjunctivitis tends to cause a watery discharge with possible preauricular lymph node involvement and is highly contagious. Bacterial conjunctivitis usually features a purulent discharge and crusting.
