What is the primary concern with a chemical-based lens care system?

The primary concern with a chemical-based lens care system is irritation. Many individuals may experience sensitivity or allergic reactions to the chemicals used in these systems, which can lead to discomfort in the eyes. This irritation can manifest as redness, itching, and a general feeling of unease, making it a significant factor for users who wear contact lenses.

In addition, irritation can deter users from consistently using their lens care products, potentially leading to inadequate eye hygiene practices. It is essential for lens care products to promote eye health without causing adverse reactions; therefore, the risk of irritation is a critical consideration in the selection and usage of these systems.

The other concerns, like cost, complication, and effectiveness, are still relevant but typically do not pose as immediate a risk or discomfort as irritation does when using chemical-based solutions.
