Bangkok:Associate Professor Dr. Sakchai Wongkittiruk, Chairman of Academic Affairs at the Royal College of Ophthalmologists of Thailand, highlights the issue of contact lens allergies, which can manifest as Giant Papillary Conjunctivitis (GPC). This condition involves chronic irritation of the conjunctiva on the inner eyelid, often leading to significant discomfort for contact lens users.
According to Thai News Agency, contact lens allergies are primarily triggered by the accumulation of protein deposits and dirt on the lenses, reactions to cleaning solutions, improper use, and mechanical friction from substandard lenses. The proteins and fats in tears adhere to the lens surface, forming allergens if not properly cleaned. Additionally, preservatives in lens solutions can cause allergic reactions, and wearing lenses for too long or beyond their lifespan increases irritation risks.
Common symptoms of contact lens allergies include itchy, irritated, and burning eyes, redness, excessive discharge, discomfort, and swollen eyelids. These symptoms require immediate attention to prevent further complications.
To manage contact lens allergies, removing the lenses and consulting an ophthalmologist for a proper diagnosis is advised. Treatment may involve antihistamine eye drops or anti-inflammatory medication. Switching to daily disposable lenses or preservative-free solutions may also help. Maintaining cleanliness and proper lens handling is crucial to avoid the development of allergies and protect eye health.
