Do GP lenses require frequent replacement?

• A. Yes
• B. No
• C. Sometimes
• D. Only when damaged

Answer: (B)

Gas-permeable lenses are rigid and durable, so they don’t need to be replaced as often as soft lenses. With proper cleaning, handling, and regular eye exams, GP lenses can last a long time—often a year or more—before a replacement is necessary. Replacement is driven by factors like damage, significant surface wear (which can affect vision or comfort), or changes in prescription, not by a need to replace on a frequent schedule. So, in general, GP lenses do not require frequent replacement. If they become damaged or the prescription changes, replacement is appropriate, but that doesn’t mean they are always replaced often.
