In addition to adaptation issues, what other factor limits GP lenses for cosmetic wear?

• A. They are not breathable
• B. They are too expensive
• C. They are not insulin tolerant
• D. Patients don't adapt well with occasional wear, and the smaller OAD cannot be used for cosmetic changes

Answer: (D)

For cosmetic GP lenses, size matters as much as fit. Even though these lenses are gas-permeable, achieving a convincing cosmetic change relies on covering enough of the eye—typically requiring a larger overall diameter to span the iris and blend with surrounding tissue. If the lens has a smaller diameter, it won’t adequately alter the appearance, can sit unevenly or decenter, and the cosmetic effect will be poor or inconsistent. So, beyond adaptation issues, the main limiting factor is the lens diameter: a smaller overall diameter can’t provide the needed cosmetic change.
