What is a disadvantage of a chemical-based rigid contact lens care system?

A chemical-based rigid contact lens care system can cause irritation, which can be a significant disadvantage for users. This type of care system often contains chemicals that are required to effectively clean and disinfect the lenses. However, these same chemicals can irritate the eyes and surrounding tissues, leading to discomfort, redness, or allergy-like symptoms in some individuals.

For many users of contact lenses, comfort is a major concern, and any product that introduces potential irritation may be less desirable. This is especially vital for individuals who may already have sensitive eyes or who use their lenses for extended periods. Therefore, while chemical-based systems can be effective in cleaning lenses, the potential for irritation presents a notable drawback, making it an important consideration for those choosing their lens care options.

In contrast, other factors such as cost, availability, and effectiveness may not necessarily convey a direct impact on the immediate user experience as irritation does, thus reinforcing why irritation is highlighted as the most significant disadvantage in this context.
