The selected answer highlights a significant concern with chemical-based rigid contact lens care systems: irritation. These systems often use strong disinfectants and preservatives that can lead to discomfort or adverse reactions, especially for individuals with sensitive eyes or those prone to allergies. This irritation can manifest as redness, dryness, or a gritty sensation in the eyes, making the wearing experience unpleasant.

While other factors such as cost, effectiveness, and availability can certainly influence the choice of a contact lens care system, irritation directly impacts the comfort and health of the user’s eyes. This discomfort may lead wearers to abandon the lens care system altogether, thereby compromising their eye health. Understanding the potential for irritation is crucial for practitioners when advising patients on lens care options and ensuring overall patient satisfaction with their contact lenses.
