What is the primary purpose of enzyme and protein removers in contact lens care?

• A. To remove stubborn deposits
• B. To disinfect lenses
• C. To moisturize lenses
• D. To color lenses

Answer: (B)

Enzyme and protein removers are used to remove protein deposits that build up on the lens surface during wear. They work by using proteolytic enzymes that break down tear proteins (like lysozyme and other protein deposits), making them easier to rinse away. This cleaning step helps keep the lens smooth and comfortable, and it can improve vision by reducing surface irregularities caused by deposits. Importantly, these products are not disinfectants themselves; disinfection requires a separate step with a disinfecting solution or system. So while enzymatic cleaners are part of the cleaning routine, they do not replace disinfection, moisturization, or color-related features of lenses.
