Why do GP lenses have a lack of disposability?

Why do GP lenses have a lack of disposability?

• A. Because they are designed for daily disposal
• B. Because there is usually only one pair, so backup glasses or CLs are needed
• C. Because they are replaced monthly
• D. Because they are frequently discarded after use

Answer: (B)

Gas permeable lenses are durable, reusable lenses that are cleaned, stored, and disinfected between wears. They’re designed for long-term use rather than single-day disposal, so a single pair can be worn for months to a year with proper care. Because of this longevity, people often have one in-use pair and a backup option (like glasses or another lens) in case the primary lens needs replacement or isn’t available. That’s why this reasoning fits best: GP lenses aren’t built for daily or frequent disposal, but for lasting wear with proper maintenance. The other ideas describe disposables or frequent replacement, which doesn’t align with how GP lenses are typically used.
