Which statement about SCL solutions and GP lenses is true?

• A. SCL solutions can be used with GPs, but GP solutions should not be used with SCLs
• B. GP solutions can always replace SCL solutions
• C. GP solutions can always replace SCL solutions
• D. SCL solutions are incompatible with GP lenses in all cases

Answer: (B)

Cleaning and disinfection are the core tasks of contact lens care. For gas-permeable lenses, the solutions marketed for GP use are typically multipurpose, meaning they can clean debris, disinfect the lens, rinse away residues, and store the lens safely. Because these products cover the same essential functions as soft-lens solutions—removing deposits, preventing microbial growth, and maintaining lens condition—they’re presented as able to replace SCL solutions in a common care regimen. Of course, you should always follow the manufacturer’s directions for the specific lens and solution involved and be aware that some regimens or materials may have unique requirements, but in this context the idea is that GP solutions can take the place of SCL solutions for routine care.
